Answer:

180 degree rotation

Step-by-step explanation:

according to the picture, we can see the wheel made half of a full rotation before it stopped. a full rotation of a circle is 360 degrees, so the car made a rotation of half of 360, which is 180 degrees.

let's check our work!

a full ride on a ferris wheel is two full rotations, which is 720 degrees. Maria rode for 1/4 of a turn which we solved for 180 degrees.

180 x 4 = 720 degrees.

our answer is correct

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

Answer:

76%

Step-by-step explanation:

For the definition of mean we can write this equation

(75 + 86 + 83 + x)/4 = 80

(244 + x)/4 = 80

244 + x = 320

x =76 %

i think its this but otherwise pay attention in class

a. Common Denominator = 8

[tex]\frac{1}{8\\}[/tex] * [tex]\frac{1}{1}[/tex] = [tex]\frac{1}{8}[/tex] /// [tex]\frac{1}{2}[/tex]*[tex]\frac{4}{4}[/tex]=[tex]\frac{4}{8}[/tex]

b. Common Denominator = 40

[tex]\frac{1}{8}[/tex] * [tex]\frac{5}{5}[/tex] =  [tex]\frac{5}{40}[/tex] ///  [tex]\frac{9}{5}[/tex] * [tex]\frac{8}{8}[/tex] =  [tex]\frac{72}{40}[/tex]  

c. Common Denominator = 24

[tex]\frac{1}{8}[/tex] * [tex]\frac{3}{3}[/tex] =  [tex]\frac{3}{24}[/tex] ///  [tex]\frac{11}{6}[/tex] * [tex]\frac{4}{4}[/tex] =  [tex]\frac{44}{24}[/tex]  

The range from 63 to 99 is where the overall population of people with red hair is most likely to fall in the interval.  

To solve:

The margin of error is equal to z (p (p - 1) / n).

4% is the error margin, We may therefore change the values to:

0.04 = z ×√ (1 - 81/625) / 625)

Then, using a standard normal table, we determine the z-value for 95%, which is around 1.96.

0.04 = 1.96 × √(81/625) × (1 - 81/625) / 625)

When we solve for (1 - 81/625)/625", we get a value of around 0.0098.

Calculations for the range are now being achieved: 

81 - (0.0098 5000) = 63 

81 + (0.0098 5000) = 99

Therefore, the range of residents with red hair that contains the greatest likelihood of lying is from 63 to 99.

The interval in which the total number of residents with red hair is most likely to lie is approximately between 545 and 745.

To find the interval in which the total number of residents with red hair is most likely to lie, we can calculate the confidence interval based on the survey results and the margin of error.

The margin of error is given as 4%, which means we have a 96% confidence level (100% - 4%). This corresponds to a z-score of approximately 1.96 for a standard normal distribution.

First, we calculate the standard error using the formula:

Standard Error = sqrt((p * (1 - p)) / n),

where p is the proportion of red-haired residents in the sample (81/625) and n is the sample size (625).

Standard Error = sqrt((81/625) * (1 - 81/625) / 625) ≈ 0.0179.

Next, we can calculate the margin of error by multiplying the standard error by the z-score:

Margin of Error = 1.96 * 0.0179 ≈ 0.035.

Now, we can calculate the lower and upper bounds of the confidence interval by subtracting and adding the margin of error, respectively:

Lower bound = (81/625) - 0.035 ≈ 0.109.

Upper bound = (81/625) + 0.035 ≈ 0.149.

To find the range or interval, we can multiply the lower and upper bounds by the total number of residents (5000):

Lower bound (rounded) = 0.109 * 5000 ≈ 545.

Upper bound (rounded) = 0.149 * 5000 ≈ 745.

Therefore, the interval in which the total number of residents with red hair is most likely to lie is approximately between 545 and 745.

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

Answer:

56 degrees

Step-by-step explanation:

Answer:

56 degrees.

Step-by-step explanation:

So within the image, you see that a right angle contains 34 degrees and an unknown value. To solve this, subtract 34 degrees from 90 to get this value. This value is 56 degrees.

Since h is a vertical angle with the 56 degree angle, it is also 56 degrees.
