Answer:
The answer is -48
Step-by-step explanation:
First step is to follow PEMDAS
So we start solving whatever is in the ( )
4^2 is in the ( ) 4^2 = 16 then we multiply
-3 * 16 which is -48

Answer: 1/3</h2>
Step-by-step explanation: 30:90 = 10:30 =1:3 = 1/3
Answer:
The probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Step-by-step explanation:

Standard deviation = 
We are supposed to determine the probability that a randomly chosen part has diameter of 3.5 inches or more

Refer the z table for p value

Hence the probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Multiply 4 by its reciprocal: 1/8x1/4= 1/32.
Call x and y those angles. If they are complementary, then their sum equals 90°:
x + y = 90°
y = 90° - x
The ratio of them is 5 to 1. So,
x/y = 5/1
x/(90° - x) = 5/1
x = 5 * (90° - x)
x = 450° - 5x
x + 5x = 450°
6x = 450°
x = 450°/6
x = 75°
The measure of the other angle is
y = 90° - 75°
y = 15°
The angles are 75° and 15°.
