Answer:
every 1/4 inch on the map is 1 mile.
You need to find the number of 1/4 inches there are in 3 1/2 inches.
There are four 1/4 inches per inch.
3 x 4 = 12
There are two 1/4 inches in 1/2 inch.
12+2 = 14
The cities are 14 miles apart.

Answer:
The answer for this question would be maybe D-
SORRY IF I'M WRONG
If a variable is binomially distributed with n trials and a success probability of p, then the mean = np, variance = np(1–p) and standard deviation = square root of variance.
In this case, n = 1200, p = 0.35. So, mean = (1200)(0.35) = 420,
variance = (1200)(0.35)(1–0.35) = 273,
standard deviation = square root of variance = √273 = 16.52.
Answer:
D. 7.29.
Step-by-step explanation:
For a Normal Distribution:
Q1 = mean - (0.675) * standard deviation
= 8.5 - 0.675*1.8
= 7.285.
