PLEASE HELP!!

An online retailer claims the probability of their packages arriving on time is 0.95. Assume that
delivery times for packages are independent of one another. Suppose that there were 14 package
deliveries. Let X = the number of packages delivered on time.

1. Explain why X is a binomial random variable.

2. Use the binomial probability formula to find P(X = 12). Interpret this value in context.

-232

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21

hope it

you would 18 *0.25 = 4.5
