Answer:15.36

Step-by-step explanation:

Took the test

Answer:

1) Z = -1.8592

2) t = 1.7139

3) p = 0.0062

Step-by-step explanation:

1) Area: (93.7+100)/2 = 193.7/2 = 96.85

Z = invNorm(0.9685,0,1) = 1.8592, but since the test is one-tailed at the lower tail, Z is actually -1.8592

2) Area: (90+100)/2 = 190/2= 95 where df=n-1=24-1=23

t = invT(0.95,23) = 1.7139

3) Since the population standard deviation is known, our test statistic is z=-2.5, making the p-value for the test p=normalcdf(-1e99,-2.5,0,1) = 0.0062

Answer:

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Step-by-step explanation:

Margin of error

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

Standard deviation of 1.3

This means that [tex]\sigma = 1.3[/tex]

She surveys 124 families

This means that [tex]n = 124[/tex]

Margin of error and meaning:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]M = 2.58\frac{1.3}{\sqrt{124}}[/tex]

[tex]M = 0.3012[/tex]

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Answer:

8 + x = 50, so Jose's saving or x = 42

Hope this helps!

Answer:

The equation is: s + 8 = 50

The amount of Jose's savings is: 42

Step-by-step explanation:

Let s = Jose's savings.

s + 8 = 50

Subtract 8 from both sides.

s = 42

The equation is: s + 8 = 50

The amount of Jose's savings is: 42

Answer: The Given plane region is missing attached below is the plane region

answer : 24 π  or 75.40 sq. units

Step-by-step explanation:

Given data :

Height of plane region = 3

base of plane region  = 4

When we revolved the plane region completely we will we forming a cone hence we will calculate for the surface area of a cone

Radius of the new cone = 3

Height of the cone = 4

slant height of the cone ( l )  = [tex]\sqrt{4^2 +3^2}[/tex]  = 5

surface area of cone = πr^2 + πrl

                                   = π ( 3 )^2  + π (3 ) ( 5 )

                                   = 24 π  or 75.40 sq. units

Answer:

(A) Yes, the vertical axis should begin at 0, not at 5.

Step-by-step explanation:

I just took the AP Stat Unit test on Edg2022 and got 100%.

When the vertical axis does not start at 0, it makes the graph look misleading.

Answer:

13 feet

Step-by-step explanation:

you can use the Pythagorean Theorem to solve this problem because the man standing on the ground forms a 90 degree angle

5² + 12² = c²

25 + 144 = c²

169 = c²

c = √169 which is 13

Answer:

  arc FG = 115°

  arc EG = 165°

Step-by-step explanation:

The first step is to understand how these arcs are arranged on a circle. The next step is to realize the whole is the sum of the parts. Arcs have the same measure as their central angle. A circle totals 360°.

  arc EF + arc FG = arc EFG . . . . parts of an arc add to give the whole arc

  80° + arc FG = 195°

  arc FG = 115° . . . . . . . . . subtract 80°

__

Similarly, parts of a circle add to give the whole circle.

  arc EFG + arc EG = 360°

  195° + arc EG = 360°

  arc EG = 165° . . . . . . . . . subtract 195°

The percent of people at the football game are not students will be 57.33%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The number of peoples in football game = 750

The number of students = 320

Now.

Find the percent of people at the football game are not students as;

Number of people are not students = 750 - 320

                                                       = 430

Thus, The percent of people at the football game are not students is;

Percent = 430 / 750 x 100

            = 0.5733 x 100

            = 57.33%

Hence, The percent of people at the football game are not students will be 57.33%.

Answer:

48 mph

Step-by-step explanation:

Convert 3 hours 15 minutes to hours.

15 minutes = 15/60 hour = 1/4

So 3 hours 15 mins = 3 1/4 hours = 13/4 hours

156 miles in 13/4 hours ==> speed = 156 ÷ 13/4 = 156 x 4/13 = 48
