Answer:
E
Step-by-step explanation:
x < -5.2
x > 5.2
How do I explain...?
95% C.I. = mean + or - 1.96(standard deviation / sqrt(sample size))
95% C.I. = 57 + or - 1.96(3.5/sqrt(40) = 57 + or - 1.085 = 57 - 1.085 to 57 + 1.085 = 55.92 to 58.09
Therefore, 95% of the mean will occur in the interval 55.92 to 58.09
Answer:
-2 times 4
Step-by-step explanation:
Answer:
B =107
Step-by-step explanation:
<B = <D
We can find <D from the sum of the angles of a triangle
32+ D +41 = 180
73+ D = 180
D = 180-73
D =107
Therefore B =107
