Consider 80 independent random variables all with the distribution given in problem 6. consider the random variable y obtained by adding together these 80 random variables. =++⋯+

a) what are the mean and standard deviation of y?
b) what is the probability y is less than 44?
c) find a number n such that there is only a 5% chance that y exceeds this number.

answer: you need the equation in the question so i can answer it

step-by-step explanation:

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

answer:

c) the x-coordinate of the center of the circle increases by 3

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
