Answer:
Step-by-step explanation:
5 consecutive multiples of 5....
x , x + 5, x + 10, x + 15, x + 20
the average is 20...
(x + x + 5 x + 10 + x + 15 + x + 20) / 5 = 20
(5x + 50) / 5 = 20
5x + 50 = 20 * 5
5x + 50 = 100
5x = 100 - 50
5x = 50
x = 50/5
x = 10......smallest number
x + 5 = 10 + 5 = 15
x + 10 = 10 + 10 = 20
x + 15 = 10 + 15 = 25
x + 20 = 10 + 20 = 30 <=== largest number
Answer:
d. exactly binomial with n = 16 and p = 0.5.
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they drink soda, or they do not. The probability of an student drinking soda is independent of any other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
50% of Americans drink soda every day.
This means that
Random sample of 16 Americans.
This means that n = 16.
So the correct answer is:
d. exactly binomial with n = 16 and p = 0.5.
12+6/7n=-25n add 25n and subtract 12 on both sides
25 6/7n=-12 convert to improper fraction
181/7n=-12 multiply both sides by seven to clear the fraction
181n=-84 divide both sides by 181 to get your answer
n= -.46 hope that helps..
