Answer:
the 4th answer I(x) = P(x-4)
Step-by-step explanation:
the first 2 options are out, because just adding values to the functional result values changes the y value, and the curve is pushed up or down. but not to the side.
just imagine
I(x) = P(x-4) means that the function value of previously at x-4 happens now at x. 4 units "later" (or more to the right).
"x+4" would make the functional value at previously x+4 happen now at x. so, everything would shift to the left (happen "earlier").
therefore, the 4th answer option is correct.
Answer:
25% of deliveries
Step-by-step explanation:
This is a uniform distribution with parameters a = 1.00 and b =5.00. With these conditions, the following probability distribution functions can be applied:

Therefore, the probability that X ≥ 4:00 p.m. is given by

Thus, 25% of deliveries are made after 4:00 p/m.
Answer:
0.21%
Step-by-step explanation:
2.5/12=0.208 or 0.21
ummm there's nothing attached
Selling price of boat: 1.3($10,000) = $13,000.
Salesman's commission: 0.25($13000-$10000) = 0.25($3000) = $750
