Hello :
answer : <span>C) x= -3 or x=5
because :
x=-3
2(-3)²-(-3)-15 = -3(-3+1)
18+3-15 =6
21-15 = 6....right
x=5
2(5)²-5-15 = 5(5+1)
50-20 =30
30=30.....right</span>
Answer:
1. $66
2. 30 + 4r
Step-by-step explanation:
Let
Price of admission into the park=$30
Price of every ride in the park=$4
Number of rides =x
Total cost of going to the park= 30+4x
1. How much money would Claire have to pay in total if she goes on 9 rides
Total cost of going to the park= 30+4x
When x=9
=30+4x
= 30 + 4(9)
=30 + 36
=$66
2. How much would she have to pay if she goes on r rides?
When x=r
Total cost of going to the park= 30+4x
= 30 + 4(r)
=30 + 4r
Answer:
The probability of a person having a driving accident while intoxicated is 0.07
Step-by-step explanation:
Hi, well, let´s put this on a formula, I think it is the best way to explain it.

Where:
P(A+I) = Probability of having a driving accident while intoxicated.
P(A) = Probability of a person of having an accident.
P(I) = Probablity person being intoxicated.
P(A or I) = Probability of a person for being intoxicated or having an accident.
Therefore, things should look like this:

So, the probability of a person having a driving accident while intoxicated is 0.07.
Best of luck.
