He decides to spin the dime again and spins it 100 times. Which of the following is a correct statement about the variability of the sampling distribution?

Since the sample size is increased, the variability will increase.
Since the sample size is increased, the variability will decrease.
Since the sample size is increased, the variability of the population will increase.
Since the sample size is increased, the variability of the population will decrease.

Answer:

231.07 in^2

Step-by-step explanation:

The radius of the semicircle is 14/2 = 7 in

22x14 - 3.14x(7^2)/2 = 231.07 in^2

Answer: 231.07 m^2

Step-by-step explanation:

Area of the remaining paperboard = Area of the entire paperboard - Area of semicircle

1. area of paperboard = l*b = 22*14 = 308 m^2

2. area of semi circle = 1/2 pi r^2 = 1/2*3.14*49/2

Therefore, area of remaining paperboard = 231.07 m^2

Answer:

-3, 9

Step-by-step explanation:

The constant is 4.

Answer:

C: $3

Step-by-step explanation:

I think you're saying that the chips cost $4, so that's what I'm going with.

You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.

Now you can subtract 1 from 4 : 4-1= $3

Hope that helps!

Answer:

D) 21

Step-by-step explanation:

y= -7/12× -36

or, y= -7×-3

or, y= 21

Answer:

D

Step-by-step explanation:

Given

[tex]\frac{-7}{12}[/tex] = [tex]\frac{y}{-36}[/tex] ( cross- multiply )

12y = 252 ( divide both sides by 12 )

y = 21 → D

Answer:

The vertical distance between Dan and Jeff is of 26 feet.

Step-by-step explanation:

Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake.

His position is -34 feet.

His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet.

Dives to 40 feet, and descends 20 more feet. So

-(40 + 20) = -60

What is the vertical distance between Dan and Jeff?

|-34 - (-60)| = |-34 + 60| = 26

The vertical distance between Dan and Jeff is of 26 feet.

Answer:

168 meters squared

Step-by-step explanation:

So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.

So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m

38-14=24

so now we know that the side is 24 and we can solve for the area

24*7=168

so the answer is 168 meters squared

Answer:

The total cost would be: $62.14

Step-by-step explanation:

First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.

Next, multiply $59.75 x .04%.  This equals $2.39.

Then, take the product and add it to $59.75. So, $59.75 + $2.39.

This equals $62.14!

Answer:

I'm not sure but from my calculations,it is 400

Answer:

400

Step-by-step explanation:

In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.

48÷0.12 or 48/0.12 = 400

Answer:

3. One Solution. (0,4). (they have different slopes and y-intercepts)

The solution can be found using elimination method:

Add the equations together

y = -x + 4

y = x - 4

2y = 0

y = 0

Solve for x

0 = x - 4

x = 4

(4, 0)

4. No solution

x + y = -2 and 3 which is not possible

The two lines would be parallel

Answer:

30°

Step-by-step explanation:

The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)

Measure of angle the ladder makes with the ground = 180 - 120 = 60°

Therefore,

The measure of angle the ladder makes with the wall = 180 - (60 + 90°)

= 30°

[tex] \frac{6}{24} \: or \: 0.25 \: or 25\%[/tex]

Step-by-step explanation:

First add them all up to get the total amount of seats.

6+10+8=24

there are 6 seats in the front row. so that means it will be

[tex] \frac{6}{24} [/tex]

24÷6=0.25

0.25×100=25%

Probability can be answered with a fraction, decimal or a percentage, they are all correct.

Answer:

The answer is c! 7,36,60,30

Step-by-step explanation:

To answer this equation you have   to find  a number that fits the description of what is required. It may seem difficult but it's not  first off it's trial and error  you have to find the right equation for every given number. For example,  what makes 15  equal 5  true? To make the equation true you have to do 15 divided by 3 equals 5  now we take the / 3 and apply them to all the other numbers  so 21 / 3 is  7 ,  36  divided by 3 is 12  hi, 60 / 3 is 20 ,  90 /3 is 30. If you have any other question like this all you have to do is trial and error with a number to make the equation true hopefully that helps! (B.t.w / symbol means divided by)
