- 12π * (3π/4 ÷ 2π) =
- 12π*3/8 =
- 9π/2
Correct choice is C
Answer:
6
Step-by-step explanation:
y = 2x + b/y=mx+c use this equation to solve the sum
using y=mx+c to solve the sum
y=2, x=-3 and m=4/3
after putting and simplifying the eq we get the value of m
Standard deviation is simply the square root of the variance.
We need to get the square root of each variance to see whether its standard deviation is greater than its variance.
A. 0.25 ⇒ √0.25 = 0.50B. 1.75 ⇒ √1.75 = 1.32C. 2.5 ⇒ √2.5 = 1.58D. 1.5 ⇒ √1.5 = 1.22
Among the choices, only A. 0.25 has a standard deviation that is greater than the variance. The standard deviation is 0.50
B = 3
3 to the second power is 9, and 4 • 9 = 36.
Answer:
8
Step-by-step explanation:
We can start by subtracting 3 from both sides of the equation:
7(x+2) + 3 - 3 = 73 - 3
We will get:
7(x+2) = 70
Now we have to figure out what times seven gives us 70:
70/7 = 10
We get the answer 10. Now we know that:
x+2 = 10
We can now subtract two from both sides of the equation:
x+2-2 = 10-2
We will get:
x = 8
