The number of jerseys that the senior class at Legion Academy can purchase for $430, using quadratic equation, is 190.

Quadratic equation is an algebraic equation of the second degree in x, represented in the form of ax²+bx+c=0.

In the quadratic equation, a, b, and c are known values but a ≠ 0 and x is unknown.

x = [-b ± √b² - 4ac]/2a

when ax^2 + bx + c = 0

C = 0 .1x² + 2.4x + 25, where C is the amount, it costs to buy x jerseys.

Simplifying the equation, we get:

x = 0.2 − 2.4 ± 40.4​

The two possible values of x are:

1) x = 0.2 − 2.4 + 40.4​ = 190

or

2) x = 0.2 − 2.4 − 40.4 ​= −214

The value of x cannot be negative, therefore, the class bought 190 jerseys for $430.

The best measure of center to describe salaries at the company is the median. The Option D is correct.

The reason is that the median is less affected by extreme values or outliers which can greatly affect the mean. In this case, the mean annual salary is $62,000 while the median is only $35,000.

This large difference suggests that there are some very high earners at the company that are pulling up the mean. The median indicates that half of the employees earn less than $35,000 and half earn more which gives a more accurate picture of the typical salary at the company.

Answer:

3(x + y + z) = k

z = k\/3 - x - y

-k + 3 x + 3 y + 3 z = 0

The value of k that makes the equation 3x + 3y + 3z = k equal to 42 is k = 14. When you substitute k = 14 into the equation, you get 3x + 3y + 3z = 42, which satisfies the condition.

To find the value of k that makes the equation 3x + 3y + 3z = k equal to 42, you need to solve for k.

The equation is:

3x + 3y + 3z = k

Now, we want this equation to equal 42, so we substitute 42 for k:

3x + 3y + 3z = 42

Next, we can simplify the equation by factoring out the common factor of 3 on the left side:

3(x + y + z) = 42.

Now, we have a simpler equation:

x + y + z = 42 / 3

Divide both sides by 3:

x + y + z = 14

So, to make the equation 3x + 3y + 3z = k equal to 42, k should be equal to 14.

Step-by-step explanation:

Answer:

(a) width = 71 ft; (b) length = 77 ft

Step-by-step explanation:

(a) The formula for area of a rectangle is

A = lw, where

Because we're already given the area and length, we can find the width by plugging everything into the formula and solve for width, w:

6319 = 89w

71 ft = w

(b) The formula for perimeter of a rectangle is

P = 2l + 2w, where

Since we're given the perimeter and width this time, we can plug everything into the formula and solve for l:

272 = 2l + 2(59)

272 = 2l + 118

154 = 2l

77 ft = l

We can check our answers for (a) and (b) by plugging in the length and width for (a) into the area formula and seeing whether we get 6319 and plugging in the length and width for (b) into the perimeter formula and seeing whether we get 272

Checking answers for (a):

6319 = 89 * 71

6319 = 272

Checking answers for (b):

272 = 2(77) + 2(59)

272 = 154 + 118

272 = 272

Based on the given data, the probabilities of the spinner landing on each color are approximately:

Red: 0.3469

Blue: 0.2449

Green: 0.0816

Yellow: 0.2449

Purple: 0.0816

To calculate the probability of the spinner landing on a specific color, we need to divide the frequency of that color by the total number of spins.

Given the spinner results:

Color Frequency

Red 17

Blue 12

Green 4

Yellow 12

Purple 4

To find the probability of landing on a specific color, we divide the frequency of that color by the total number of spins:

Probability (Red) = Frequency (Red) / Total Spins

= 17 / (17 + 12 + 4 + 12 + 4)

= 17 / 49

= 0.3469 (rounded to four decimal places)

Probability (Blue) = Frequency (Blue) / Total Spins

= 12 / 49

= 0.2449 (rounded to four decimal places)

Probability (Green) = Frequency (Green) / Total Spins

= 4 / 49

= 0.0816 (rounded to four decimal places)

Probability (Yellow) = Frequency (Yellow) / Total Spins

= 12 / 49

= 0.2449 (rounded to four decimal places)

Probability (Purple) = Frequency (Purple) / Total Spins

= 4 / 49

= 0.0816 (rounded to four decimal places)

The graph is an absolute value graph merged with inequality. hence the attributes of inequality which involves shading of the graph will be seen in the graph

To create a table of values for the inequality |x| + 1 < 3, we can evaluate the inequality for each value of x within that range.

For x = -2:

|(-2)| + 1 < 3

2 + 1 < 3

3 < 3

This inequality is not true for x = -2.

For x = -1:

|(-1)| + 1 < 3

1 + 1 < 3

2 < 3

This inequality is true for x = -1.

For x = 0

|(0)| + 1 < 3

0 + 1 < 3

1 < 3

This inequality is true for x = 0.

For x = 2:

|(2)| + 1 < 3

2 + 1 < 3

Answer:

18 square units

Step-by-step explanation:

The parallelogram has been plotted in the attached figure

The area of a parallelogram is b x h

where b is one side and h is the vertical distance between the two bases

In the figure, we see that base = AB is parallel to the y-axis

This means the y-coordinates of A and B are the same and the distance is obtained by taking the absolute difference between the x-coordinates of A and B

b = |x1 - 2| = |6 - 0| = 6

The height h is a perpendicular line from point D(1, 3) to the base which touches the base at point E

Since this line is horizontal to the x-axis in the figure, the y coordinates of the endpoints of the line are the same i.e y1 =3 and y2 = 3

Therefore h = absolute difference between the x coordinates
= |1-4| = 3

Given b = 6, h = 3

area = 6x 3 = 18 square units

The coordinates of point S are  (4, 3.5)

Remember that the coordinates of a point are written in the notation (x, y), such that the first value is the value in the horizontal axis, and the second value is the value in the vertical axis.

Each one of the squares is one unit, then the x-value of the point S is:

x = 4

And for the y-value we can see that the point is halfway between the third and the fourt lines, then:

y = 3.5

Thus, the coordinates of point S are (4, 3.5)

The equation that passes through the point (4, -3) and has a slope of 4 is option A: 5x + 4y = 8.

To determine which equation passes through the point (4, -3) and has a slope of 4, we can substitute the values of x and y into each equation and check if the resulting equation is true.

Let's substitute x = 4 and y = -3 into each equation:

A. 5x + 4y = 8

Substituting x = 4 and y = -3:

5(4) + 4(-3) = 20 - 12 = 8

The equation is true for points (4, -3).

B. 5x - 4y = 8

Substituting x = 4 and y = -3:

5(4) - 4(-3) = 20 + 12 = 32

The equation is not true for points (4, -3).

C. 4x + 5y = 8

Substituting x = 4 and y = -3:

4(4) + 5(-3) = 16 - 15 = 1

The equation is not true for points (4, -3).

D. 4x - 5y = 8

Substituting x = 4 and y = -3:

4(4) - 5(-3) = 16 + 15 = 31

The equation is not true for points (4, -3).

The size of the land that Muya's son and daughter received is [tex]1\frac{11}{12}[/tex] hectares.

We can see that, Muya started with a [tex]6\frac{2}{3}[/tex] hectares piece of land, which we can write as an improper fraction i.e.:

[tex]6\frac{2}{3}[/tex] = (6 × 3 + 2) / 3 = [tex]\frac{20}{3}[/tex] hectares

The Muya donated [tex]\frac{7}{8}[/tex] hectares to a school and [tex]1 \frac{1}{2}[/tex] hectares to a children's home. The total amount of land he donated is:

[tex]= \frac{7}{8}+ \frac{11}{2} \\\\= \frac{7}{8} + \frac{3}{2} \\\\= \frac{14}{8} + \frac{12}{8} \\\\= \frac{26}{8} \\\\= \frac{13}{4} hectares[/tex]

The size of the land left is:

[tex]\frac{20}{3} - \frac{13}{4} = (\frac{80}{12}) - (\frac{39}{12}) = \frac{41}{12} hectares[/tex]

Muya's son and daughter share this remaining land equally, so each of them gets:

[tex](\frac{41}{12}) / 2 = \frac{20.5}{12} = 1 \frac{11}{12} hectares[/tex]

First, we need to arrange the data in order. We can convert the mixed numbers to improper fractions for ease of comparison:

1/3, 2/1, 4/1, 1/1, 7/3, 4/5, 5/2

Now, let's arrange them in ascending order:

1/3, 4/5, 1, 7/3, 2, 5/2, 4

The median is the middle value in the data set. Since we have an odd number of values, the median is the middle value when the data is arranged in order. Therefore, the median is:

median = 2

Therefore, the correct option is C

Answer:

1.5

Step-by-step explanation:

1/3    2    4    1    7    2/3    4/5    5/2

Write the numbers in ascending order.

1/3    2/3    4/5    1    2    5/2    4    7

The median is the middle value if there is an odd number of numbers.

If there is an even number of numbers, the median is the mean of the middle two numbers.

Here, there are 8 values, so we do the mean of the middle 2 values.

median = (1 + 2)/2

median = 1.5

This question involves using the binomial distribution.

Let X be the number of male high school lacrosse players who will play at the college level out of the 20 selected players . We can model X as a binomial random variable with parameters n=20 and p=0.128, where p is the probability of success (i.e., a player going on to play at the college level).

The probability of exactly 4 players playing at the college level is given by the formula:

P(X=4) = (20 choose 4) * (0.128)^4 * (1-0.128)^(20-4)

Using a calculator, we can evaluate this expression to find:

P(X=4) = 0.155

Therefore, the probability that exactly four of the 20 male high school lacrosse players selected at random will end up playing at the college level is 0.155, or between C and 1 (inclusive).
