Answer:
a=2
b=6
Step-by-step explanation:
Assuming a uniform distribution and that a ≤ x ≤ b, if f(x) = 1/4, then:

If P(X > 4) = 1/2, then:

The values for a and b are, respectively, 2 and 6.
You have a 1/2 chance of spinning an even number on the spinner, and a 1/2 chance of rolling an odd number on the die, 1/2 times 1/2 give you a 1/4 chance of doing both of those tasks.
The coordinates of C are (a+c, b)
Coordinates of midpoint of AC are (a+c/2, b/2)
Coordinates of BD are (a+c/2, b/2)
Y 50 I think it is I am not to sure
D
Remember starts at zero slope is up 4 right 1
Y= 4/1x+0
Y=4x
