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:

it will take her 30 minutes long

Answer

30 minutes

Step-by-step explanation:

6 is half of 12 and Nancy is moving 12 mph. half of an hour is 30 minutes so the answer would be 30 minutes.

Answer:

maybe it is 3600 m not sure though

[tex]\frac{30}{75}[/tex] divide each number by 5.

[tex]\frac{6}{15}[/tex] divide each number by 3

[tex]\frac{2}{5}[/tex]

Therefore, the reduced form is

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

I think it is 10 miles.

I hope this helps! :)

Answer:

24.84

Step-by-step explanation:

Answer:

y = 2x - 5

Step-by-step explanation:

y-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We know the slope is 2, so all that's left is to find the y-intercept. To do this, for every 1 we subtract from x in (4,3), we take away 2 from y because the slope is two. We keep doing this until x is zero. The remaining y-value is the y-intercept.  

Answer:

[tex]y = 2x-5[/tex], see below.

Step-by-step explanation:

There is enough information to make a point slope equation that we can later convert into slope intercept.

Point slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

[tex](x_1,y_1): \text{A point.} \\\\m - \text{Slope.}[/tex]

We are given the slope of 2 and the point (4,3).

Replace the variables with the given information.

[tex]y-y_1=m(x-x_1)\rightarrow y-3=2(x-4)[/tex]

With the equation we will now convert it into slope intercept form:

[tex]y-3=2(x-4)\\\\y-3=2x-8\\\\y-3+3=2x-8+3\\\\\boxed{y=2x-5}[/tex]

Hope this helps!

Answer: $2184

Step-by-step explanation:

(6800)(0.028)(12) = 2184

1.) f^-1(x) = x/3 -2

2.)f^-1(x) = 5x/6 + 5/2

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:

Step-by-step explanation:

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:

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:

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
