liter goal has Cara consumed thus far?

Answers

Answer 1

Cara has consumed 139/425 of her 212 1/2 liter water goal.

To find the fraction of her 212 1/2 liter goal that Cara has consumed, we can divide the amount she has consumed by her total goal

Fraction consumed = amount consumed / total goal

Fraction consumed = 34 3/4 / 212 1/2

To make it easier to work with, we can convert the mixed numbers to improper fractions

Fraction consumed = (434 + 3) / (2212 + 1)

Fraction consumed = 139 / 425

Therefore, water consumed 139/425 of cara is 212 1/2 liter goal.

If a book about airplanes costs $5.39, how much would it cost to buy 5 books about airplanes?

Answers

Answer:

$5.39 × 5 = $26.95

5 books about airplanes would cost $26.95.

It would cost roughly $26.95, because one book cost $5.39, so if you were to buy 5 books, multiply 5.39 by 5 you would get 26.95

The teacher's null hypothesis is that #p=0 while his alternative hypothesis is >0. Based on the data in the table and using a significance

Answers

The P-value is 0.003, so he must reject the null hypothesis.

What is the correct P-value and conclusion?

To determine the correct answer, we need to perform a statistical hypothesis test.

The null hypothesis is that the mean difference between pretest scores and posttest scores (μd) is equal to 0. The alternative hypothesis is that the mean difference is greater than 0.

To perform this hypothesis test, we can use a paired-sample t-test, since we have two sets of scores from the same students. The formula for the t-statistic is: t = (Md - μd) / (sd / sqrt(n))

Using the data from the table, we can calculate the mean difference, standard deviation, and t-statistic as follows:

Mean difference (Md) = 84.33 - 81.33 = 3

Standard deviation (sd) = 2.622

t-statistic = (3 - 0) / (2.622 / sqrt(18)) = 3.13

To find the p-value, we need to look up the t-distribution with 17 degrees of freedom (since we have 18 paired observations) and a one-tailed test (since the alternative hypothesis is one-tailed). At a significance level of 0.01 and 17 degrees of freedom, the critical t-value is 2.567.

The p-value is the probability of getting a t-statistic as extreme or more extreme than the observed t-statistic, assuming the null hypothesis is true. From the t-distribution table, we can see that the p-value corresponding to a t-statistic of 3.13 with 17 degrees of freedom is approximately 0.003.

Since the p-value is less than the significance level of 0.01, we can reject the null hypothesis and conclude that there is sufficient evidence to suggest that the mean difference between pretest scores and posttest scores is greater than 0, indicating that the students have mastered the material in their statistics unit.

which of the following statements is false? a.) a larger sample size would increase the power of a significance test. b.) the significance level is the probability of making a type i error. c.) expanding the sample size can decrease the power of a hypothesis test. d.) the probability of rejecting the null hypothesis in error is called a type i error.

Answers

The statement C is false .

why the statement C is false ?

a)A larger sample size would increase the power of a significance test because it provides more information, reduces random error, and increases the precision of the estimate.

b.) The significance level is the probability of making a type I error, which is rejecting the null hypothesis when it is actually true. It is usually denoted by α and is set before conducting a hypothesis test.

c.) Expanding the sample size cannot decrease the power of a hypothesis test. Power is the probability of rejecting the null hypothesis when it is false (i.e., correctly detecting a real effect). A larger sample size generally increases the power of a test, making it more likely to detect a true effect.

d.) The probability of rejecting the null hypothesis in error is called a type I error. It occurs when the null hypothesis is actually true but is rejected based on the sample data. The probability of making a type I error is equal to the significance level (α) of the test.

Each letter in the word ORLANDO is written on a card and put into a bag. What is the theoretical probability of choosing an “O”, putting it back and then drawing a “A”.

Answers

Hence, The theoretical probability of selecting a "O", returning it to the bag, and then selecting a "A" from the collection is 2/21.

What is the probability?

The probability  of an occurrence is a number used in mathematics to describe how likely it is that the event will take  place. In terms of percentage  notation, it is expressed as a number  between 0 and 1, or between 0% and 100%. The higher the likelihood, the more  likely it is that the event will take place.

What is the event in probability?

In probability theory,  an event is a set of outcomes  of an experiment to which a probability is assigned. A single outcome may be  an element of many different events, and different events  in an experiment are usually not equally likely, since they may include  very different groups of outcomes.

The  word  "ORLANDO"  consists of 7 letters,

in this word  "ORLANDO"  the  O letter is 2 times  and A is one times

probability  of "O" letters  is 2/7  before  there are two "O"s in  total out of the  seven letters because we are putting the first letter back before drawing the second.

After  that, there are  still 2 "O"s and 1 "A" in the bag for  the  second draw because  we placed the first "O" back. Because there is only one "A" out of a  possible three letters,  the probability  of drawing one on the second draw is one in three.

We multiply the   probabilities of each occurrence  to determine the probability that both will occur:

P("O" on the first draw)* P("A" on the second draw) = (2/7) * (1/3) = 2/21

The theoretical probability of selecting a "O", returning it to the bag, and then selecting a "A" from the collection is therefore 2/21, or roughly 0.095, or 9.5%.

Answers

Huseyin used a vertical stretch, so the quadrilateral aren't similar. So correct option is A.

Describe Quadrilateral?

A quadrilateral is a geometric shape that consists of four straight sides and four angles. It is a polygon because it is a closed shape with multiple straight sides.

There are various types of quadrilaterals, which are classified based on their properties. Some common types of quadrilaterals include squares, rectangles, rhombuses, parallelograms, trapezoids, and kites.

A square is a quadrilateral with four equal sides and four equal right angles. A rectangle has four right angles but opposite sides are equal. A rhombus has four equal sides, but its angles are not necessarily right angles. A parallelogram has opposite sides that are parallel and equal in length, but its angles are not necessarily right angles. A trapezoid has only one pair of opposite sides that are parallel. A kite has two pairs of adjacent sides that are equal in length.

We know that that two quadrilateral are similar if corresponding angles are congruent and measures of their corresponding sides are proportional.

In the given transformation, angles that corresponding to each other are

∠fEH and ∠JEK

Answers

The lake activity with a central angle of  [tex]39.6^\circ[/tex] is Wakeboarding.

What is the central angle?

11. the number of tortilla sandwich wraps falling into each interval can be represented by the height or area of the bars. This allows for an easy visualization of the distribution of the data.

12. To determine which bus typically has the faster travel time, we need to compare the measures of center for each data set. Since there are outliers in both data sets, the median would be a more appropriate measure of center than the mean.

For Bus 14, the median is (10 + 12)/2 = 11.

For Bus 18, the median is (10 + 14)/2 = 12.

Therefore, Bus 18 typically has the faster travel time, with a median of 12 minutes.

13. The IQR (interquartile range) is the best measure of variability for the data because it is less sensitive to outliers than the range, and it gives us an idea of how spread out the middle 50% of the data is.

To find Q1, we need to find the median of the lower half of the data: (1+2)/2 = 1.5.

To find Q3, we need to find the median of the upper half of the data: (8+8+8)/3 = 8.

Therefore, the IQR = Q3 - Q1 = 8 - 1.5 = 6.5.

14. To determine the central angle of each lake activity, we need to calculate the percentage of campers who chose each activity and then multiply that percentage by 360 (the total degrees in a circle).

The percentage of campers who chose Kayaking is 15%, so the central angle would be 0.15 x 360 = 54°.

The percentage of campers who chose Wakeboarding is 11%, so the central angle would be 0.11 x 360 = 39.6°.

The percentage of campers who chose Windsurfing is 7%, so the central angle would be 0.07 x 360 = 25.2°.

The percentage of campers who chose Waterskiing is 13%, so the central angle would be 0.13 x 360 = 46.8°.

The percentage of campers who chose Paddleboarding is 54%, so the central angle would be [tex]0.54 x 360 = 194.4^\circ.[/tex]

An animal population N(t) is modeled by the differential equation:
dN/dt = -0. 001N(N - 110)(N - 99). If N(0)=A, where A is a positive integer, what is the maximum value of the positive integer A such that extinction will occur?

Answers

For the given integer, the maximum starting population size that will eventually lead to extinction is 98, since any larger value will result in the population either stabilizing at a positive value or growing indefinitely.

The equation in question is:

dN/dt = -0.001N(N - 110)(N - 99)

Here, N represents the population size, and dN/dt represents the rate of change of the population with respect to time. The right-hand side of the equation tells us how the population size changes over time, and it's determined by the current population size N, as well as the two constants 110 and 99.

We can do this by setting dN/dt equal to zero and solving for N:

dN/dt = -0.001N(N - 110)(N - 99) = 0

=> N = 0, N = 99, N = 110

We can then plot the direction field (i.e., arrows indicating the direction of change) on each interval, and use this to determine the behavior of the solution curve. In this case, we can see that the direction of the arrows changes at each critical point, indicating that the population behavior switches between growing and declining as we move from one interval to the next.

Specifically, we can see that if the initial population size A is less than 99, the population will decline to extinction. If the initial population size is between 99 and 110, the population will initially decline but then grow and eventually stabilize at N = 110. If the initial population size is greater than 110, the population will grow exponentially and tend towards infinity.

There are 12,620,256 different combinations of 31 balloons that can be chosen from the store's inventory of 8 colors, each with at least 31 balloons.

We can use the method of example 9.6.2, which involves using the combination formula. We know that there are 8 colors of balloons and at least 31 of each color. We have 8 options for the first balloon, 8 options for the second balloon, and so on, for a total of 8 options for each of the 31 balloons.

Using the combination formula, we can calculate the number of different combinations of 31 balloons that can be chosen as follows:

[tex]nCr = n! / (r! \times (n-r)!)[/tex]

where n is the total number of options (in this case, 8), and r is the number of items we are choosing (in this case, 31).

Plugging in these values, we get:

[tex]8C31 = 8! / (31! \times (8-31)!)[/tex]

[tex]= 8! / (31! \times (-23)!)[/tex]

Answers

Part A: A reasonable domain to plot the growth function would be from d = 0 to d = 11.

Part B: The y-intercept of the graph of the function f(d) is 7

Part C: The average rate of change of the function f(d) from d = 4 to d = 11 is approximately 0.64 mm/day.

Domine and y-intercept of a function:

The domain of a function represents the set of input values for which the function is defined and can produce a meaningful output.

The y-intercept of a function represents the value of the function when the input is equal to zero.

The average rate of change of a function from x = a to x = b is given by the slope of the secant line passing through the points (a, f(a)) and (b, f(b)).

Here we have

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

=> f(d) = 7(1.06)^d

Since it is given that the radius of the algae was approximately 13.29 mm when the biologist concluded her study, we can set f(d) = 13.29  

=> 13.29 = [tex]7(1.06)^{d}[/tex]

=> ln(13.29/7) = d ln(1.06)

=> d = ln(13.29/7)/ln(1.06) ≈ 11  

Therefore, A reasonable domain to plot the growth function would be from d = 0 to d = 11.

Part B: The y-intercept of the graph of the function f(d) represents the value of the function when d = 0.

Substituting d = 0 into the given equation, we get:

f(0) = 7(1.06)⁰ = 7

Therefore, The y-intercept of the graph of the function f(d) is 7

Part C: The average rate of change of the function f(d) from d = 4 to d = 11 is given by the slope of the secant line passing through the points (4, f(4)) and (11, f(11)). Using the given equation, we can evaluate f(4) and f(11):

f(4) = 7(1.06)⁴ ≈ 8.84

f(11) = 7(1.06)¹¹ ≈ 13.29

The slope of the second line passing through these two points is:

Slope = (f(11) - f(4))/(11 - 4) = [ 13.29 - 8.84]/7 = 0.64

Therefore,

The average rate of change of the function f(d) from d = 4 to d = 11 is approximately 0.64 mm/day.

Coach Sanchez is setting up a court for
a game of four-square. He has a
square space, with an area of 64
square feet. What is the longest side
length Coach Sanchez can make for
one side of the court?

Answers

Thus, coach Sanchez can only create a side length of 8 for one side of the court, which is the longest side length.

Explain about the square root:

The factor of a number that, when multiplied by itself, equals the original number is known as the square root of the number. Practically speaking, determining a number's square root is the reverse of doing so to find its square.

Properties

A perfect square root corresponds to a perfect square number.The square root of an even perfect number is even.The square root of an odd perfect number is odd.

You only need to find that square root of the area to determine the length of a side because we know that a square already has equal sides so the area is determined by two sides.

√64 = 8

Thus, coach Sanchez can only create a side length of 8 for one side of the court, which is the longest side length.

Multiply 13. 5 x 12. 1 using a regrouping strategy. Explain your answer and each step that you take

Answers

The product of 13.5 and 12.1 using a regrouping strategy is 163.35.

To begin with, we can start by breaking down each number into its place value components, which are the ones, tenths, and hundredths places. We can represent 13.5 as 13 + 0.5 and 12.1 as 12 + 0.1.

So, we can rewrite 13.5 as (10 + 3) + 0.5 and 12.1 as (10 + 2) + 0.1. Now, we can use the distributive property of multiplication to multiply 13.5 by 12.1 as follows:

13.5 x 12.1 = (10 + 3 + 0.5) x (10 + 2 + 0.1)

= 10 x 10 + 10 x 2 + 10 x 0.1

+ 3 x 10 + 3 x 2 + 3 x 0.1

+ 0.5 x 10 + 0.5 x 2 + 0.5 x 0.1

Next, we can simplify each of these products by multiplying the numbers in the ones and tenths places separately, and then adding the results. For example, 10 x 10 = 100, 10 x 2 = 20, 10 x 0.1 = 1, 3 x 10 = 30, and so on.

So, continuing from the previous step, we get:

13.5 x 12.1 = 100 + 20 + 1

+ 30 + 6 + 0.3

+ 5 + 1 + 0.05

Finally, we can add up all these products to get the final answer:

13.5 x 12.1 = 163.35

what is Right triangle ?

A right triangle is a triangle that has one angle equal to 90 degrees (a right angle). The other two angles are acute angles (less than 90 degrees). The side opposite to the right angle is called the hypotenuse, and the other two sides are called legs.

In the given question,

The ratio of the legs of the right triangle for a ramp should be 1:12, which means that for every 1 inch of rise, there should be 12 inches of ramp length. To calculate the angle of inclination, we can use the inverse tangent function, which gives us the angle whose tangent is equal to the ratio of the legs. The angle of inclination should be less than or equal to 4.8 degrees.

Let's calculate the angle of inclination for each ramp design:

Right triangle with legs 3 meters and 33 meters:

The ratio of the legs is 3:33, which simplifies to 1:11. The length of the ramp is 11 times the height of the rise. The angle of inclination is:

arctan(1/11) ≈ 4.76 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 1 meter and 15 meters:

The ratio of the legs is 1:15. The length of the ramp is 15 times the height of the rise. The angle of inclination is:

arctan(1/15) ≈ 3.81 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design also meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 12 meters and 140 meters:

The ratio of the legs is 12:140, which simplifies to 3:35. The length of the ramp is 35 times the height of the rise. The angle of inclination is:

arctan(3/35) ≈ 4.56 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 12 meters and 150 meters:

The ratio of the legs is 12:150, which simplifies to 2:25. The length of the ramp is 25 times the height of the rise. The angle of inclination is:

arctan(2/25) ≈ 4.62 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 24 meters and 240 meters:

The ratio of the legs is 24:240, which simplifies to 1:10. The length of the ramp is 10 times the height of the rise. The angle of inclination is:

arctan(1/10) ≈ 5.71 degrees

The angle of inclination is greater than 4.8 degrees, so this ramp design does not meet the requirements of the Americans with Disabilities Act.

Therefore, the ramp designs that meet the requirements of the Americans with Disabilities Act are:

Right triangle with legs 3 meters and 33 meters.

Right triangle with legs 1 meter and 15 meters.

Right triangle with legs 12 meters and 140 meters.

Right triangle with legs 12 meters and 150 meters.

Mia removes the plug from a trough to drain the water. The volume, in gallons, in the trough after it has been unplugged can be modeled by f(x) = 10x2 −19x + 6, where x is time in minutes. Which of the following equations will reveal the time in minutes when the trough is empty?

Answers

Therefore, the time in minutes when the trough is empty is approximately 0.313 minutes.

To find the time in minutes when the trough is empty, we need to solve the equation f(x) = 0, since f(x) represents the volume of water in the trough.

So, we need to solve the quadratic equation:

[tex]10x^2 - 19x + 6 = 0[/tex]

To solve this equation, we can use the quadratic formula:

[tex]x = (-b ± \sqrt(b^2 - 4ac)) / 2a[/tex]

where a = 10, b = -19, and c = 6.

Plugging in these values, we get:

[tex]x = (-(-19) ± \sqrt((-19)^2 - 4(10)(6))) / 2(10)[/tex]

[tex]x = (19 ± sqrt(241)) / 20[/tex]

So, the two solutions are:

[tex]x = (19 + \sqrt(241)) / 20 \approx1.807 minutes[/tex]

[tex]x = (19 - \sqrt(241)) / 20 \approx0.313 minutes[/tex]

However, only the second solution makes sense in this context, since the trough cannot be empty before we start draining the water. Therefore, the time in minutes when the trough is empty is approximately 0.313 minutes.

50 POINTS!!!! Rewrite the function by completing the square f(x) = x^2 - 8x - 2

Answers

Answer:

The rewritten function by completing the square is:

[tex]f(x)=(x-4)^2-18[/tex]

The solutions of the function are:

[tex]x=4+3\sqrt{2},\;x=4-3\sqrt{2}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=x^2-8x-2[/tex]

To rewrite the function by completing the square, begin by adding and subtracting the square of half the coefficient of the term in x. (Place these between the term in x and the constant).

[tex]f(x)=x^2-8x+\left(\dfrac{-8}{2}\right)^2-\left(\dfrac{-8}{2}\right)^2-2[/tex]

Simplify:

[tex]f(x)=x^2-8x+\left(-4\right)^2-\left(-4\right)^2-2[/tex]

[tex]f(x)=x^2-8x+16-16-2[/tex]

We have now created a perfect square trinomial from the first three terms: x² - 8x + 16.

[tex]\boxed{\begin{minipage}{8.5 cm}\underline{\sf \large Perfect Square Trinomial}\\\\\sf A perfect square trinomial is a polynomial of the form $a^2 + 2ab + b^2$ or $a^2 - 2ab + b^2$, where $a$ and $b$ are constants. \\\\When factored, a perfect square trinomial becomes the square of a binomial: $(a + b)^2$ or $(a - b)^2$. \\\end{minipage}}[/tex]

Factor the perfect square trinomial x² - 8x + 16.

[tex]f(x)=(x-4)^2-16-2[/tex]

Simplify by subtracting the numbers outside the parentheses:

[tex]f(x)=(x-4)^2-18[/tex]

Therefore, the given function rewritten by completing the square is:

f(x) = (x - 4)² - 18

The solutions to a quadratic function are the x-values which satisfy the equation f(x) = 0. Therefore, to find the solutions, set the function equal to zero and solve for x.

[tex]\begin{aligned}f(x)&=0\\\implies (x-4)^2-18&=0\\(x-4)^2-18+18&=0+18\\(x-4)^2&=18\\\sqrt{(x-4)^2}&=\sqrt{18}\\x-4&=\pm\sqrt{18}\\x-4+4&=\pm\sqrt{18}+4\\x&=4\pm\sqrt{18}\\x&=4\pm\sqrt{3^2 \cdot 2}\\x&=4\pm\sqrt{3^2} \sqrt{2}\\x&=4\pm3 \sqrt{2}\end{aligned}[/tex]

Therefore, the solutions of the function are:

[tex]x=4+3\sqrt{2},\;x=4-3\sqrt{2}[/tex]
