13. Suppose you had to guess on a four-choice multiple-choice test and were given four questions . Find the binomial probability distribution. (p + q)^n when n = 4 and p = 0.25

Binomial probability distribution = 1

Step-by-step explanation:

According to the question:

the binomial probability distribution = (p + q) ^n

Probability of success, p = 0.25

p + q =  1

Probability of failure, q = 1 - p

q = 1 - 0.25 = 0.75

number of guesses, n = 4

Binomial probability distribution = (0.75 + 0.25) ^ 4

Binomial probability distribution = 1^4

Binomial probability distribution = 1

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
