Answer: 151.25 cm^2
explanation: separate into rectangle and semi circle. you can find out the diameter and radius of the semi circle by subtracting the 6 from the top from the 16 of the bottom because the diameter of the circle plus the 6 take up the same length.
16 - 6 = 10
for radius divide by 2
10 / 2 = 5
area of rectangle: l x w
16 x 7 = 112
area of semi circle: 1/2(pi)r^2
1/2(3.14)5^25 = 39.25
add up the two areas to find the area of the entire figure
112 + 39.25 = 151.25
Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m = = -
Answer:
Part A: x = 6
Part B: S = 3.51

How to Find the Mean
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Calculate the mean of 2,3,4,5,8,8,12
Step 1: Add all the numbers together, to find the sum
2 + 3 + 4 + 5 + 8 + 8 + 12 = 42
Step 2: Count the number of values in your data set
There are 7 numbers
Step 3: Divide the sum by the count
42 ÷ 7 = 6
So the mean is 6
