Answer:

13.7 cm

Step-by-step explanation:

there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
since we know that 360°-260.4°=99.6°
The angle measure of arc AD is 99.6°

Now that we covered that, we can use the arc length formula in order to find the length of arc AD.

arc length = 2πr(Θ/360°)
2π(7.9)(99.6°/360°) = 13.7329
rounded to the nearest tenth = 13.7

The weekly incomes of a large group of executives are normally distributed with a mean of $2,000 and a standard deviation of $10

cestrela7 [59]

Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.

μ =2000, σ =100

We have to find z score for income $2100 i.e x=2100

Z = $\frac{x-mean}{standard deviation}$

= $\frac{2100 - 2000}{100}$

Z = 100/100

Z = 1

The z score for income $2100 is 1
