Answer:
f^-1(x)=1/5x-2
Step-by-step explanation:
f(x) = 5x + 10
Use substitution
y = 5x + 10
Interchange the variables
x = 5y + 10
Swap the sides
5y + 10 = x
Move the constant to the right
5y = x - 10
Divide both sides
y = 1/5x-2
Use substitution
f^-1(x)=1/5x-2
Final Answer
Hope this helped!
Answer:
The expected value for the number of defects on a randomly selected plastic part is 0.43.
Step-by-step explanation:
We have the following probability distribution:
P(X = 0) = 0.79
P(X = 1) = 0.09
P(X = 2) = 0.05
P(X = 3) = 0.04
P(X = 4) = 0.03
What is the expected value, E(X), for the number of defects on a randomly selected plastic part?
Each value multiplied by its probability. So
The expected value for the number of defects on a randomly selected plastic part is 0.43.
Answer:
11.40
Step-by-step explanation:
If we were to divide the shape into a rectangle and triangle, we would have the base of the triangle as 9 because two sides of the rectangle are equal, and 7 for the side because two sides of rectangle are equal and 14/2 is 7. Now we have two sides of a triangle 9 and 7. We know X is the hypotenuse because it is opposite to the right angle. We will plug it into the pythagorean theorem.
a^2+b^2=c^2
9^2+7^2=c^2
81+49=c^2
130=c^2
