Answer:
0.47
Step-by-step explanation:
First, find P(X > 1.18).
(2 − 0) / 1 = (2 − 1.18) / x
2x = 0.82
x = 0.41
Next, find P(X < 0.12).
(2 − 0) / 1 = (0.12 − 0) / x
2x = 0.12
x = 0.06
So the total probability is 0.41 + 0.06 = 0.47.
Volume without holes = 3 x 6 x 11 = 198 cubic inches.
Calculate volume of one hole:
3.14 x 0.5^2 x 3 = 2.355 cubic inches
There are 3 holes: 3 x 2.355 = 7.065
Subtract volume of the holes from the brick:
198 - 7.065 = 190.935 cubic inches.
Rounded to the nearest tenth: 190.9 cubic inches.
14^2+48^2=x^2
196+2304=x^2
2500=x^2
x=50
hypotenuse equals 50
5.7^2 + 9.8^2 - 10.2^2 / 2*5.7*9.8 =
24.49/111.72 = 0.219 = 0.22
answer is 0.22
