b.) 4

Step-by-step explanation:

a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.

b.) To find the mean add up all the numbers in the frequency column.

3+2+7+8+0=20

Divide that by the amount of numbers. There are 5 numbers so 20/5=4.

Answer:

y=2

Step-by-step explanation:

1/3 (y+7) = 3(y-1)

Multiply each side by 3 to get rid of the fraction

3*1/3 (y+7) = 3*3(y-1)

y+7 = 9(y-1)

Distribute

y+7 = 9y - 9

Subtract y from each side

y+7-y = 9y-y-9

7 = 8y -9

Add 9 to each side

7+9 = 8y-9+9

16 = 8y

Divide each side by8

16/8 = 8y/8

2 = y

If the circumference of a circle measures

RoseWind [281]

<h2>Therefore the area of the circle is = $289\pi$ $cm^2$ </h2>

Step-by-step explanation:

Given that the circumference of a circle measures $34 \pi$ cm

Let the radius of the circle be = r

Then circumference = $2 \pi r$ cm

According to problem

$2 \pi r$ = $34 \pi$

⇔ $r = \frac {34}{2}$

⇔ $r = 17$ cm

Therefore the area of the circle is = $\pi r^2$

= $\pi 17^2$ $cm^2$

= $289\pi$ $cm^2$
