Answer:
13
Step-by-step explanation:
You are given the function

To find the value of the function f(x) at point x=a, you have to substitute a instead of x into the function expression.
In your case, you have to evaluate f(x) when x=10. Substitute 10 instead of x into the function expression:

If line r is parallel to line q, they have the same slope which is -2. You can use the point-slope formula <span>y-y₁=m(x-x₁) and plug in 8 for y and -8 for x. Solve for y to get the equation in slope-intercept form (y = mx + b). "M" is the slope.</span>
Answer:
0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Dinosaur
Event B: Plush.
The probability that a toy Raymond picks out of a box is a dinosaur is 75%.
This means that 
The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%.
This means that 
What is the probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur?

0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.
The answer is 4/3 because you need to use the formula
