Answer:
212.7
Step-by-step explanation:
Calculation to Find P60 the score which separates the lower 60% from the top 40%
First step is to find z of 60% using the invNorm distribution
Hence,
z=0.6=0.2533
Now let Find P60 which is the score which separates the lower 60% from the top 40% using this formula
x<=>z
Where,
Standard deviation=50
Mean=200
z=0.2533
Let plug in the formula
x=0.2533*50+200
x=12.665+200
x=212.665
x=212.7(Approximately)
Therefore the score which separates the lower 60% from the top 40% is 212.7
Answer:
A. h = 4
B. g = 15
C. b = -6
D. b = 15
Step-by-step explanation:
A. 9h + 8 - 12 = -40
9h - 4 = -40
+ 4 + 4
9h = -36
h = -4
B. 9 + 6g + 1 = 100
10 + 6g = 100
- 10 - 10
6g = 90
g = 15
C. -45 = 28 - 13 + 10b
-45 = 15 + 10b
- 15 - 15
-60 = 10b
b = -6
D. 37 = 11 +3b - 19
37 = 3b - 8
+ 8 + 8
45 = 3b
15 = b

<u>The correct answer is D. 414 in squared.</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Area of the first circle = 11.5 inches ²
2. Let's calculate the area of the new circle, given that the radius of the first circle is multiplied by 6.
Area of the first circle = 11.5 inches ²
Let's find the radius:
π * r² = 11.5
r² = 11.5 / 3.1416
r² = 3.66055513
r = 1.91 inches
The first circle has a radius of 1.91 inches
So, the radius of the second circle is 1.91 * 6 = 11.48 inches
Area of the second circle = π * r²
Area of the second circle = 3.1416 * 11.48²
Area of the second circle = 3.1416 * 131.79
Area of the second circle = 414.03 inches ²
<u>Area of the second circle = 414 inches ² (Rounded to the nearest whole number)</u>
<u>The correct answer is D. 414 in squared.</u>
