Answer:
1/5
Step-by-step explanation:
the prob that you will pick a blue marble would be 12/16, easy.
then the prob of picking a yellow marble after that would be 4/15 since one marble is already missing. multiply the numerator and denominator of each fraction. so 12 x 4 and 16 x 15 to get 48/240. then divide each by 48 to get 1/5.
Answer:
459 sales people.
Step-by-step explanation
Time per call (t) = 45 min = 0.75 h
Hours per sales person (H) = 3,400 hours
Number of customers (n) = 40,000 customers
Call frequency (f)= 52 calls per year
The total number of sales people (S) needed, is given by the total time spent on calls for the year, divided by the amount of hours each person spends on sale:

Rounding up to the next whole person, Pringles needs 459 sales people.

Answer:
The center is (2, -7)
Step-by-step explanation:
A circle is given by
(x-h)^2 + (y-k)^2 = r^2
where(h,k) is the center and r is the radius
(x - 2)^2 +(y + 7)^2 =169
(x - 2)^2 +(y - -7)^2 =13^2
The center is (2, -7) and the radius is 13
