X side. Y side

1. 3

2. 5

3. 7

4. 9

5. 11

Step-by-step explanation:

We can see that ix x = 1 and y = 3, then that means 1+2

then its 2+3 then 3+4 and so on

So 43 + 44 = 87

So y should equal 87 :)

HELP FAST SO CONFUSED<br><br> Find the area of the shaded sector. Leave your answer in terms of π.

ddd [48]

Total area: pi*9^2 = 81pi

Shaded area = Total area / 3, because 120/360 = 1/3

So Shaded area = 81pi/3 = 27pi

GEOMETRIC PROBABILITY AID?

viva [34]

Find the area of small and large circles:

$A_{small}=\pi r_1^2=\pi \cdot (8.01)^2=64.1601,\\ A_{large}=\pi r_2^2=\pi \cdot (4.02)^2=16.1604$ .

The area of the shaded region is

$A_{shaded}=A_{large}-A_{small}=64.1601-16.1604=47.9997$ .

Use the geometric probability to determine the probability that randomly selected point will be in the shaded region:

$Pr=\dfrac{A_{shaded}}{A_{large}} =\dfrac{47.9997}{64.1601} =0.7481$ .

In percent 0.7481 is 74.81% and rounded to the nearest tenth is 74.8%.

Answer: 74.8%.
