Answer:
The larger number is 96.
Step-by-step explanation:
Step-by-step answer:
standard deviation (sigma) = 12 inches
mean (mu) = 90 inches.
For 36 years, the standard error of the mean is
e = sigma / sqrt(n) = 12" / sqrt(36) = 2".
Deviation from the mean
= 92.8 -90 = 2.8
Since the standard error of the mean follows the normal distribution, we have
Z=(92.8-90)/2 = 1.4
Looking up the normal distribution tables, or check R, we find
P(Z>1.4) = 1-P(Z<1.4) = 1-0.9192433 = 0.08075666
Answer: P(snowfall>92.8) = 0.0808 (to four decimal places)
Answer:
b
Step-by-step explanation:
Answer:
g(-2) = -19
g(0) = -5
g(3) = -14
Step-by-step explanation:
- g(-2)= -2(-2)2 + 3(-2) - 5
-
9(-2)= -2(4) - 6-5
-
g(-2)= - 8 - 11
- g(-2) = -19
<u>This is a quadratic function and its form is:</u>
<u>Calculation of g(0) and g(3) below:</u>
- g(0) = -2*0² + 3*0 - 5
-
g(0) = -5
------------------
- g(3)= -2*3² + 3*3 - 5
- g(3) = -18 + 9 - 5
- g(3) = -14
