z = (x - μ)/σ
Substituting given values, you have
3.6 = (x - 132)/20
(20)(3.6) = x - 132 . . . . multiply by 20
72 + 132 = x . . . . . . . . .add 132
204 = x
The value that has a z-score of 3.6 is 204.
First you would find the difference of 210 and 46, so 210-46=164.
Then you will divide the solution by the total number of students, so
164 divided by 210.
164/210= about .780 or 78%
Surface area = 4πr²
⇒ 400 = 4 * 3.14 * r²
⇒ r² = 400/12.56
⇒ r² = 31.84
⇒ r = √31.84 = 5.64 inches
Answer is A.
Hope it helps!
Answer:
y = -x + 8
Step-by-step explanation:
m = -1 ; x1 = 3 ; y1 = 5
Slope point form: y - y1 = m(x -x1)
y - 5 = -1(x - 3)
y - 5 = -1x - 3 *(-1)
y - 5 =-x + 3
y = -x + 3 + 5
y = -x + 8
2 3/20 ,2 9/20, 2 1/2,2 11/20,2 4/5
