Answer:

• 25%

• Drama movie

Step-by-step explanation:

• Total number of children

= 16 +12 +18 +20 +14

= 80

Percentage of children that voted for action movie

[tex] = \frac{no. \: of \: children \: that \: voted \: for \: action \: movie}{total \: number \: of \: children} \times 100\%[/tex]

[tex] = \frac{20}{80} \times 100\%[/tex]

[tex] =\textbf{25\%}[/tex]

------------------------------------------------------------

• Total number of votes

= 30 +32 +36 +36 +26

= 160

20% of total votes

= 20% ×160

= 32 votes

Since Drama movie received 32 votes, it received 20% of the total votes.

Answer:

The answer is -0.828

Step-by-step explanation:

I took the quiz and i gt this question correct, hope it helps!

The r-value of the given data is 0.374.

The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.

It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.

We have,

First, we need to find the correlation coefficient (r) of the given data.

We can use the following formula to do this:

r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]

where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.

Using the given data, we can calculate the values as follows:

n = 5

∑x = 39

∑y = 53

∑(xy) = 442

∑x^2 = 483

∑y^2 = 1249

Substituting these values into the formula, we get:

r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]

r = [2210 - 2067] / [√(2415) √(5660)]

r = 143 / (61.898 75.245)

r = 0.374 (rounded to three decimal places)

Therefore,

The r-value of the given data is 0.374.

Step-by-step explanation:

The sales price of the items sold by the 6 friends given the total amount made is $1.40.

In order to determine the sales price, divide the total amount made by the total amount of the items sold

Sales price = $25.20 / (6 x 3) = $1.40

Step-by-step explanation:

The graphs can be seen in the picture attached below where

y= sin x is the red wave

y= sin 2x is the blue wave

y=2 sin x  is the green wave

Each graph is obviously a wave in shape but where they all differentiate is in the frequency and amplitude of the wave. Meaning how often a wave cycle repeats in the functional and how high and low the wave cycles actually get. That is where the difference takes place sinx has wider wave cycles than the other two. sin2x has the shortest wave cycles, almost twice for everyone red wave cycle. While 2sinx has the highest and lowest amplitude of all of the waves.

Answer:

a = 0.8

Step-by-step explanation:

a varies jointly as b and c.

This means that a can be written as a constant k multiplied by b multiplied by c, that is:

[tex]a = kbc[/tex]

One set of values is a = 2.4, b = 0.6, and c = 0.8.

We use this to find the value of k:

[tex]2.4 = k(0.8)(0.6)[/tex]

[tex]0.48k = 2.4[/tex]

[tex]k = \frac{2.4}{0.48}[/tex]

[tex]k = 5[/tex]

So

[tex]a = 5bc[/tex]

Find a when b = 0.4 and c = 0.4.

[tex]a = 5bc = 5(0.4)(0.4) = 5(0.16) = 0.80[/tex]

The answer is a = 0.8.

Answer:

342yd^2

Step-by-step explanation:

Hope this helps!

Answer:

342yd^2

Step-by-step explanation:

The way I find surface area is by laying out the box and finding the area of each square seperately and then adding them together.

First, I placed the 7 on the wing to the side because that is the width.

Next, I placed the 13 on the long side of the big box because that is the length.

Then, I placed the 4 on the small side of the big box because that is the width.

After that I just did the multiplication for each box.

2(7•13) + 2(7•4) + 2(13•4) = 342

You can apply this same strategy to any surface area problem like this. The format will change based on the shape but that's pretty much it. Hope this helped

Answer:

A. Slope = -³/2

B. y = -³/2x - 6

C. ³/2x + y = -6

Step-by-step explanation:

A. Slope of the line would be the negative reciprocal of the slope of 2x - 3y = 12, which is written in standard form. Rewrite in slope-intercept form, y = mx + b, where m = slope.

Thus:

2x - 3y = 12

-3y = -2x + 12

y = -2x/-3 + 12/-3

y = ⅔x - 4

The slope of 2x - 3y = 12 is therefore ⅔.

The slope of the line perpendicular to 2x - 3y = 12 would be the negative reciprocal of its slope, ⅔ which is:

-³/2

Therefore, the slope of the line perpendicular to 2x - 3y = 12 is -³/2

B. To find the equation of the line in slope-intercept form, first find the equation in point-slope form using the point given (-6, 3) and slope of the line, -³/2.

Substitute a = -6, b = 3, and m = -³/2 into y - b = m(x - a).

Thus:

y - 3 = -³/2(x - (-6))

y - 3 = -³/2(x + 6)

Rewrite in slope-intercept form, y = mx + b

Multiply both sides by 2

2(y - 3) = -3(x + 6)

2y - 6 = -3x - 18

2y = -3x - 18 + 6

2y = -3x - 12

y = -3x/2 - 12/2

y = -³/2x - 6

C. Rewrite y = -³/2x - 6 in standard form.

y = -³/2x - 6

³/2x + y = -6

Answer:

The test value is z = -1.31.

Step-by-step explanation:

The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150.

This means that the null hypothesis is that the mean is this value, that is:

[tex]H_0: \mu = 125150[/tex]

The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed.

This means that at the alternate hypotehsis we test that the mean is lower than that value, that is:

[tex]H_a: \mu < 125150[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

125150 is tested at the null hypothesis:

This means that [tex]\mu = 125150[/tex]

Standard deviation of $7,350.

This means that [tex]\sigma = 7350[/tex]

A sample of 36 homes for sale in this subdivision had an average selling price of $123,550.

This means that [tex]n = 36, X = 123550[/tex]

Compute the test value.

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{123550 - 125150}{\frac{7350}{\sqrt{36}}}[/tex]

[tex]z = -1.31[/tex]

The test value is z = -1.31.

Answer:

80°

Step-by-step explanation:

In rhombus, opposite angles are equal. i.e <KET = <KIT

Triangle KET is isoceles, which means both parts of angle E are equal.

Angle E = 80

If angle E is 80 than Angle I is also 80.

Answer:

25π

Step-by-step explanation:

pi's symbol is π, which will be used sometimes to make it easier later

The circumference is equal to diameter multiplied by pi. (Diameter is the length across the circle, radius the center of the circle to an edge point aka. half the diameter, and circumference is the edge length aka. perimeter of the circle.)

We can then remove the pi off the 10, as the diameter multiplied by pi is the circumference, so the diameter is 10.

Half of 10 is 5, the radius.

The formula for area of a circle is radius squared times pi, remember easily by π r ^2

We can plug in the radius into the formula to get

π 5 ^2

And finish it by solving the square root to get

π 25
