Here are the midterm exam scores for a very small population of students. Student A: 94
Student B: 82
Student C: 76
Student D: 68
(a) List all 6 possible SRSs of size n = 2, and calculate the mean midterm score for each sample
(b) How would the sampling distribution change if we took SRSs of size n = 3 instead

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
