Answer:
Option d) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
Step-by-step explanation:
Given that the amount of rainfall each month over the past four years is shown below.
The histogram appears as a reflection on the vertical line through the middle
The rainfall first is maximum then decreases gradually after minimum increases gradually so that it equals the start amount
Thus the histogram is perfectly symmetrical
It is not skewed to left or right

Step-by-step explanation:
The formula to calculate the circumference if you know the radius is as follows: Circumference = 2 x Radius x π π = Pi = 3.14, thus, the math to calculate the circumference of a circle with a radius of 17 is: 2 x 17 x 3.14 = 106.76
Answer:
a = 3 b = -4
Step-by-step explanation:
4 (0.1a -0.4b) = (1.9) 0.4a - 1.6b = 7.6
0.4a - 1.6b = 7.6
- 0.4a +0.5b = -0.8
-2.1b = 8.4
b = -4
0.4a + 0.5(-4) = -0.8
0.4a - 2 = -0.8
0.4a = 1.2
a = 3
