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)
Perimeter = w + w + l + l
180= w+w+w+12+w+12
The dimensions for width are just w and for length it's w+12
Answer:
73.43
Step-by-step explanation:
To find any hypotenuse use the Pythagorean theorem:
- First, square 36 (which would be 36 x 36) and square 64 (64 x 64).
- Add them together.
- Find the square root of the total.
- That's your answer :)

18-36= -18
Answer:
It is irrational and equal to 6 times the square root of 2.
Step-by-step explanation:
√50 + √2
= √25 * √2 + √2
= 5√2 + √2
= 6√2.
