On a busy fall weekend, the wait time for a randomly selected customer to get cider and donuts at a local cider mill is uniformly distributed with a minimum of 4 minutes and a maximum of 32 minutes (as well as a mean of 18 minutes and standard deviation of 8 minutes). Q4.1 and Q4.2 require a numeric input; no work is necessary. Make sure to include 4 decimal places. Q4.12 Points What is the probability that a randomly selected customer will wait for more than 20 minutes

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
