A dressmaker needs to cut 4-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 4-inch pieces can the dressmaker cut from 15 of these rolls of
ribbon?
Before you try that problem, answer the question below.
How many inches of ribbon does the dressmaker have, in
total?

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

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
