Answer:

Step-by-step explanation:

Divide one sample of jumping jacks by each girl by their time to find the unit rate. Then compare unit rates. Recall, a unit rate is the number of jumping jacks done in one minute. Cortney does 15 jumping jacks in 1 minute in the first entry of the table. Mallory does 60 jumping jacks in 5 minutes according to a point on the graph. Divide 60/5=12. She does 12 jumping jacks per minute. Thus Cortney does 3 more per minute.

<h3>What is a normal distribution?</h3>

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

the graph is shown below.

Then the different of the means of the distribution will be

⇒ 45 - 30

⇒ 15

Then the correct option is A.

The area of a circle with radius r is given by the formula A=πr2. If a circle has area 81π square inches, what is the radius (in

Ksenya-84 [330]

The Solution:

GIven:

$A=\pi r^2$

Required:

$Find\text{ }r\text{ when }A=81\pi in^2$

Substitute:

$\begin{gathered} \pi r^2=81\pi \\ \\ r^2=\frac{81\pi}{\pi}=81 \end{gathered}$

Take the square root of both sides:

$\begin{gathered} r=\sqrt{81}=\pm9 \\ \\ r=9in\text{ \lparen discard r=-9 since }r>0) \end{gathered}$

Answer:

9 inches

What is the arc length of the subtending arc for an angle of 72 degrees on a circle of radius 4? 8 4 5 16 5 8 5

german

You can calculate the arc lenght by using this formula:
arc length = 2π*r*(A/360) , where A=angle of the arc.

So for you it would be:
arc length = 2π*4*(72/360) = 5.03

I hope that helped.
