What is number?

Number is the concept of a mathematical object used to count, measure, and label. It is an abstract concept, though most familiar in the form of numerals such as "3" or "10". Numbers allow us to compare and manipulate amounts, sequences, shapes, and patterns. They also allow us to create models and make predictions. As a result, they are essential tools in a variety of disciplines, from mathematics and physics to engineering and economics.

Let x be the number of mangoes in each group on Monday. The expression representing the number of mangoes in each group is x + 4/2 = x + 2.

b) Let y be the number of mangoes in each group on Tuesday. The expression representing the number of mangoes in each group is 2y + 2/3 = 2y + 2/3.

c) Let z be the number of mangoes left after subtracting the number of mangoes in each group on Tuesday from the number of mangoes in each group on Monday. The equation representing this information is x + 2 - (2y + 2/3) = z.

d) Substituting the expression for x and y in the equation, we get: (2y + 2/3) + 2 - (2y + 2/3) = z.

Solving the equation, we get z = 2.

Hence, the number of mangoes she picked is 2.

If $f(x)=4x^3+1$, find $f^{-1}(33)$.

Answers

The value of the inverse function of f(x), that is, f⁻¹(33) is 2.

How is the inverse function of a given function found?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function. In general, switching the coordinates x and y is how an inverse is calculated. Although not strictly a function, this freshly constructed inverse is a relation.

To guarantee that the original function's inverse will likewise be a function, the original function must be a one-to-one function. Only when every second element matches the first value is a function deemed to be a one-to-one function.

Given that,

f(x)=4x³+1

Also, f⁻¹(33).

Thus, using the input and output corresponding values we have:

f(x) = 4x³ + 1 = 33

x³ = 8

Taking the cube root of both sides, we get:

x = 2

Hence, the value of the inverse function of f(x), that is, f⁻¹(33) is 2.

How to obtain the vertices of the image?

The original vertices of the triangle are given as follows:

X(6, -2), Y(4,1) and Z(-2,3).

The vertices of the image are obtained applying the transformations in the context of the problem.

The first transformation is T(5,-4), which is a translation, meaning that 5 is added to the x-coordinate of each vertex, while 4 is subtracted from the y-coordinate of each vertex, hence:

X'(11, -6), Y'(9,-3) and Z'(3,-1).

The final transformation is the dilation with a scale factor of 1.5, meaning that each coordinate of each vertex is multiplied by 1.5, hence:

X'(16.5, -9), Y'(13.5,-4.5) and Z'(4.5,-1.5).

The area of a rectangular rug is given by the trinomial r^2 - 8r - 33. What are the possible dimensions of the​ rug? Use factoring.

Answers

The required possible dimensions of the​ rug are 11   by  [tex]\frac{r^2 - 8r - 33}{11}[/tex].

How to factor the equation to find dimensions?

The area of the rectangular rug is given by the trinomial:

[tex]$r^2 - 8r - 33$[/tex]

To find the possible dimensions of the rug, we need to factor this trinomial. We can do this by finding two numbers that multiply to -33 and add up to -8. These numbers are -11 and 3:

[tex]$r^2 - 8r - 33 = (r - 11)(r + 3)$[/tex]

Therefore, the possible dimensions of the rug are:

[tex]$r - 11 = 0$[/tex] or [tex]$r + 3 = 0$[/tex]

[tex]$r = 11$[/tex]or $[tex]$r = -3$[/tex]

Since the dimensions of the rug cannot be negative, we can only take the positive value of r, which is r = 11.

Therefore, the possible dimensions of the rug are:

11   by  [tex]\frac{r^2 - 8r - 33}{11}[/tex]

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 pounds. The truck is transporting 50 large boxes and 60 small boxes. If the truck is carrying a total of 3800 pounds in boxes, how much does each type of box weigh?

Answers

Answer:  Large box weight 40 pounds, and small box weight 30 pounds.

Step-by-step explanation:

Let L be the weight of a large box, and S be the weight of a small box.

L + S = 70

50L + 60S = 3800

We change the first equation into the form of L, and we get:

L = 70 - S

And we plugin L = 70 - S into the second equation.

  50(70 - S) + 60S = 3800

3500 - 50S + 60S = 3800

          3500 + 10S = 3800

         -3500             -3500

                       10S = 300

                          S = 30

 L + S = 70

L + 30 = 70

  - 30     - 30

       L = 40

Leticia invests $200 at 5% interest. If f(x) represents the amount of money after x time periods, which exponential function best represents this situation?

Answers

The amount of money Leticia has after x time periods can be calculated using the formula:

f(x) = P(1 + r)^x

where P is the principal (initial amount invested), r is the annual interest rate (expressed as a decimal), and x is the number of time periods.

Substituting the given values, we get:

f(x) = 200(1 + 0.05)^x

Simplifying this expression, we get:

f(x) = 200(1.05)^x

Therefore, the exponential function that best represents this situation is:

f(x) = 200(1.05)^x

However, if the question is x^2 - x - 20 = 0,

x = 4, -5

Step-by-step explanation:

WARNING: Your question is incorrect and so, I have tweaked it to make it correct

Completing the square of (x^2 + x - 20):

(x^2 - x) - 20

= (x^2 - x + (1/2)^2 - (1/2)^2) - 20

= (x^2 - x + (1/4))^2 - 1/4 - 20

= (x-1/2)^2 - 81/4

Hence,

(x-1/2)^2 - 81/4 = 0

(x-1/2)^2 = 81/4

x-1/2 = + or - 9/2

x = 9/2 + 1/2 (OR) x = -9/2 + 1/2

x = 5 (OR) x = -4

Answer:

x = 1/2 + √(79)/2 * i or x = 1/2 - √(79)/2 * i

Step by step explanation:

To solve the equation x²-x+20=0 using completing the square method, we need to follow these steps:

Move the constant term to the right side of the equation:
x² - x = -20
Take half of the coefficient of x (-1/2), square it (1/4), and add it to both sides of the equation:
x² - x + 1/4 = -20 + 1/4
Factor the left side of the equation as a square of a binomial:
(x - 1/2)² = -79/4
Take the square root of both sides of the equation:
x - 1/2 = ±√(-79/4)
Note that the square root of a negative number is an imaginary number, so we can simplify the expression on the right side of the equation as follows:

√(-79/4) = √(79)/2 * i

where i is the imaginary unit.

Add 1/2 to both sides of the equation:
x = 1/2 ± √(79)/2 * i
Therefore, the solutions to the equation x² - x + 20 = 0 using completing the square method are:

x = 1/2 + √(79)/2 * i or x = 1/2 - √(79)/2 * i

A normal population has a variance of 9.0. A random sample of size 9 and

Answers

We can cοnclude that the variance frοm this randοm sample is nοt significantly different frοm 9.0 at a 5% level οf significance.

What is Variance?

In mathematics, variance is a measure οf the spread οr dispersiοn οf a set οf data values. It is calculated as the average οf the squared differences frοm the mean. Variance is cοmmοnly used in statistics tο assess the variability οf a data set and is an impοrtant parameter in many statistical analyses.

Tο test whether the variance frοm this randοm sample is equal tο 9.0, we can use a chi-square test. The test statistic fοr this hypοthesis test is calculated as:

chi-square = (n - 1) × sample variance / pοpulatiοn variance

where n is the sample size.

Substituting the given values, we get:

chi-square = (9 - 1) × 8.01 / 9.0

chi-square ≈ 6.71

The critical chi-square value at a 5% level οf significance and 8 degrees οf freedοm (n - 1) is 15.51. Since the calculated chi-square value οf 6.71 is less than the critical chi-square value οf 15.51, we fail tο reject the null hypοthesis that the variance frοm this randοm sample is equal tο 9.0. In οther wοrds, there is nοt enοugh evidence tο suggest that the variance frοm this randοm sample is different frοm 9.0 at a 5% level οf significance.

-9x + 3y = 27
-3x + 4y = 24

Answers

The slope of the equation -9x + 3y = 27 is greater and this line has a greater rate of change.

What is rate of change?

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one thing by the equal amount of change in another. In the slope-intercept form for a line, the rate of change m for a linear function is written as y=mx+b, whereas the rate of change of functions is defined as (f(b)-f(a))/b-a.

The standard equation of the line is given as:

y = mx + c

where, m is the slope of the line.

For the given equation of lines, transform them into standard equation:

-9x + 3y = 27

3y = 9x + 27

Divide both sides of the equation with 3:

y = 3x + 9

Here, the slope of the equation is 3.

For, -3x + 4y = 24

4y = 3x + 24

Divide both sides of the equation by 4:

y = 3/4x + 6

The slope of this line is 3/4.

Comparing the slope of the two lines we see that,

3 > 3/4

Hence, the slope of the equation -9x + 3y = 27 is greater and this line has a greater rate of change.

Answer:

a. X ~ N(6.1, 1.2^2)

b. The median seedless watermelon weight is 6.1 kg.

c. The Z-score for a seedless watermelon weighing 7 kg is 0.75.

d. The probability that a randomly selected watermelon will weigh more than 5.1 kg is 0.7967.

e. The probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg is 0.2454.

f. The 85th percentile for the weight of seedless watermelons is 7.2437 kg.

Step-by-step explanation:

a. X ~ N(6.1, 1.2^2)

b. The median of a normal distribution is equal to the mean, so the median seedless watermelon weight is 6.1 kg.

c. The Z-score for a seedless watermelon weighing 7 kg can be calculated as:

Z = (7 - 6.1) / 1.2 = 0.75

Therefore, the Z-score is 0.75.

d. To find the probability that a randomly selected watermelon will weigh more than 5.1 kg, we need to standardize the value using the formula:

Z = (X - μ) / σ

where X is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

Z = (5.1 - 6.1) / 1.2 = -0.8333

Using a standard normal distribution table or a calculator, we can find the probability that Z is greater than -0.8333 to be 0.7967.

Therefore, the probability that a randomly selected watermelon will weigh more than 5.1 kg is 0.7967.

e. To find the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg, we need to standardize the values and find the area under the normal curve between the two Z-scores. The Z-scores for 5.3 kg and 6 kg are:

Z1 = (5.3 - 6.1) / 1.2 = -0.6667

Z2 = (6 - 6.1) / 1.2 = -0.0833

Using a standard normal distribution table or a calculator, we can find the probability that Z is between -0.6667 and -0.0833 to be 0.2454.

Therefore, the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg is 0.2454.

f. The 85th percentile for the weight of seedless watermelons can be found by finding the Z-score that corresponds to the 85th percentile of a standard normal distribution. Using a standard normal distribution table or a calculator, we can find the Z-score to be 1.0364.

To find the corresponding weight, we can use the formula:

Z = (X - μ) / σ

1.0364 = (X - 6.1) / 1.2

X = 7.2437

Therefore, the 85th percentile for the weight of seedless watermelons is 7.2437 kg.

e) 0.2143    (or 21.43%)
f) 7.3435 kg (using excel)    or      7.348 kg (using normal tables)

Step-by-step explanation:

a) normal distribution just need to be define we his mean and his standard deviation. You just need a sample higher than 30 or to be specified the population is normally distributed
X≈N(μ,σ)= N(6.1,1.2)

b) The median and mean are not necessarily the same, for a normal distribution, which is a symmetric distribution, those values are just the same


c) The equation for Z score is given by:

[tex]z=\frac{x-u}{\sigma}[/tex]

Replacing values:

[tex]Z=\frac{7-6.1}{1.2} =0.75[/tex]


d) first find the Zvalue for 5.1

[tex]Z=\frac{5.1-6.1}{1.2} =-0.83[/tex]

Now, find the probability from  Normal  Distribution table
P(Z>0.83) = 0.7977


e)

first find the Zvalue fo5.3 and 6

[tex]Z=\frac{5.3-6.1}{1.2} =-0.67[/tex]


[tex]Z=\frac{6-6.1}{1.2} =-0.08[/tex]

Now find probabilities from  Normal Distribution  table . Notice you need to subtract   P(Z>0.08)-P(Z>0.67) if you use a positive table.

P(-0.67<z<-0.08) = 0.2143


f) Find the Z score from a   Normal  Distribution table that give you an area of 0.8500 (or the closest value), im using excel for this one since the answer from tables have only TWO decimals and can be problematic if you need more decimal places.

this gives a Z of 1.036433389

now use the Zscore equation but solve for X

[tex]z\sigma+u=x[/tex]

x = 1.036433389(1.2)+6.1 = 7.3437   (Using excel)


If i use a table, the closes is 1.04 (0.8508 which is not exactly 0.85)

x = 1.04(1.2)+6.1= 7.348 (using table)

Question 1
Christi alters a skirt. She cuts 7 inches off the bottom of the skirt and then adds a 5-
inch ruffle to the skirt's remaining bottom edge. Which expression best represents the
final length of the skirt?
Os-12
O2+s
02-s
1 pts
OS-2

Answers

Step-by-step explanation:

Let's call the original length of the skirt "l". After cutting 7 inches off the bottom, the remaining length of the skirt is l-7. Then, when Christi adds a 5-inch ruffle, the final length of the skirt becomes:

(l-7) + 5

Simplifying this expression, we get:

l - 2

Therefore, the expression that best represents the final length of the skirt is:

O2 - s

Write an equation for the hyperbola shown In the graph.

Answers

The equation for the hyperbola is [tex]y^{2} -4x^{2} =144[/tex]

Define the term hyperbola ?

A hyperbola is a type of conic section, formed by the intersection of a plane with two cones that have a common vertex. It consists of two separate curves that are mirror images of each other, each of which has two branches that extend to infinity.

By Given figure,

C = (0, 0)

V (0, ±6)

b = 6

equation of asymptotes;  [tex]y=[/tex] ±[tex]\frac{a}{b}x[/tex]

then, y = ± [tex]\frac{a}{6} * x[/tex]

given the asymptotes, y = ±2x

by comparing we get, a/6 = 2

a = 12

We know the equation of hyperbola,   [tex]\frac{y^{2} }{a^{2} } -\frac{x^{2} }{b^{2} } =1[/tex]

putting the values of a and b,     [tex]\frac{y^{2} }{12^{2} } -\frac{x^{2} }{6^{2} } =1[/tex]

[tex]\frac{y^{2} }{144} } -\frac{x^{2} }{36} } =1[/tex]

After Simplification, [tex]y^{2} -4x^{2} =144[/tex]

Therefore, the equation for the hyperbola is [tex]y^{2} -4x^{2} =144[/tex]

Answer:

Reflection only

The mirror line must pass through one of the sides of the triangle.

============================================================

Explanation:

The term "invariant" means "does not vary" i.e. "does not change".

An invariant point is fixed in place.

Here are the list of geometric transformations

Translation (aka shifting)RotationReflectionDilation

Some geometry textbooks will mention "glide reflection", but that's really just a combination of translation and reflection. That means we can ignore it.

Let's go through each item to see if we can get two vertices to stay glued in their spot.  

With translations, it's impossible to have invariant points. Every point will change location. Therefore, we cannot have two invariant vertices for any translation. We cross translation off the list.Rotations are a little better. We have one point that doesn't move: the center of rotation. Unfortunately every other point that isn't the center will rotate around the center (and hence change location). We cross rotations off the list.Reflections are the transformation that will be able to hold two vertices fixed in place. Any point on the mirror line will not change location. If we draw the mirror line through a side of the triangle, then it will guarantee two vertices will stay in place. This is why reflection is the only answer.Dilations are similar to rotations in that they have one invariant point. The center of dilation stays where it is, but everything else moves closer to the center (if the scale factor is between 0 and 1) or moves away from the center (if the scale factor is larger than 1). We cross dilations off the list.

In short we have eliminated: translations, rotations, and dilations. The only thing that works is reflections

What is function?

Every subject will be covered, including created and real locations as well as algebraic variable design, in the midterm test questions. a schematic illustrating the connections between various components that work together to produce the same outcome. A service is made up of many unique parts that work together to produce unique outcomes for each input.

Here,

A function's difference quotient, f(x), is provided by:

=> [f(x+ h) - f(x)] / h

where h denotes a slight modification to the x-value.

The difference quotient for the function f(x) = -3/x can be calculated as follows:

=> [f(x + h) - f(x)] / h

=> [-3/√(x + h) + 3/√x] / h (substituting x + h for x in the function)

=>  [-3√x + 3√(x + h)] / [h√x√(x + h)] (finding a common denominator and combining the terms)

=> [-3√x + 3√(x + h)] / h / √x√(x + h) (dividing by the denominator)

Therefore, the difference quotient of f(x) is:

=> [-3√x + 3√(x + h)] / h / √x√(x + h)

The difference fraction of f(x) is thus:

=> [-3√x + 3√(x + h)] / h / √x√(x + h)

Find the cost of buying 150 stamps using the table above=
Find the cost of buying 213 stamps with the table above=

Answers

Step-by-step explanation:

For a 151kg parcel, we can see that it falls under the category of "Over 100kg and up to 500kg", so the cost would be 21.10 Naira per kg:

Cost of sending 151kg parcel = 21.10 Naira/kg * 151 kg = 3187.10 Naira

For a 507kg parcel, we can see that it falls under the category of "Over 100kg and up to 500kg", so the cost would be 21.10 Naira per kg:

Cost of sending 507kg parcel = 21.10 Naira/kg * 507 kg = 10701.70 Naira

To find the cost of buying stamps, we need to check which category the number of stamps falls under. For 150 stamps, it falls under the category of "Over 10 stamps up to 50 stamps", so the cost would be 75.00 Naira:

Cost of buying 150 stamps = 75.00 Naira

For 213 stamps, it falls under the category of "Over 50 stamps up to 100 stamps", so the cost would be 105.00 Naira:

Cost of buying 213 stamps = 105.00 Naira

The value of x that maximizes the area of the figure is 1.5 inches, and the maximum area is 3.375 square inches.

What is rectangle ?

A rectangle is a two-dimensional form that has four full sides and four right angles. Because the opposing sides are parallel and congruent, it is a unique kind of parallelogram.

To find the maximum area of the figure, we need to determine the value of x that will maximize the area.

The area of the figure can be calculated as:

A = (1.5x)(x) + (1/2)(1.5x)(6-2x)

Simplifying the expression:

[tex]A = 1.5x^2 + 4.5x - 3x^2[/tex]

[tex]A = -1.5x^2 + 4.5x[/tex]

To find the value of x that maximizes the area, we need to take the derivative of A with respect to x and set it equal to zero:

dA/dx = -3x + 4.5 = 0

Solving for x:

3x = 4.5

x = 1.5 inches

Now that we know x=1.5 inches maximizes the area, we can substitute it back into the area equation to find the maximum area:

[tex]A = -1.5(1.5)^2 + 4.5(1.5)[/tex]

A = 3.375 square inches

Therefore, the value of x that maximizes the area of the figure is 1.5 inches and the maximum area is 3.375 square inches.
