Answer:
The probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
Step-by-step explanation:
We are given that
n=4
We have to find the probability that the average score of a group of n = 4 people is between 70 and 75.
Hence, the probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
Answer:
551
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
=
( first + last)
The number of terms is
= a + (n - 1)d ← d is the common difference, a is the first term
d = 5 - 2 = 8 - 5 = 3, hence
2 + 3(n - 1) = 56
2 + 3n - 3 = 56
3n - 1 = 56 ⇒ 3n = 57 ⇒ n = 19
=
( 2 + 56 ) = 19 × 29 = 551
