Hi there! :)
<u>Answer:</u>
Donovan babysat for 7 hours on Saturday in order to earn $31.50.
Step-by-step explanation:
In order for you to answer your question, you'll need to use the cross product method:
$9 → 2 hours
$31.50 → X hours
<u>(2 × 31.50)</u> ÷ 9 = X hours
<u>63 ÷ 9</u> = X hours
<u>7 = X hours</u>
There you go! I really hope this helped, if there's anything just let me know! :)

Answer:
Pr(only one of them will pass the driving test) = 0.38
Step-by-step explanation:
The probability that Ben will pass = 0.8
Let Pr = pribability
Pr(Ben pass) = 0.8
Pr(Ben fail) = 1 - Pr(Ben pass) = 1-0.8
Pr(Ben fail) = 0.2
The probability that Tom will pass = 0.7
Pr (Tom pass) = 0.7
Pr (Tom fail) = 1 - Pr (Tom pass) = 1-0.7
Pr (Tom fail) = 0.3
Pr(only one pass) = Pr(Ben pass and Tom fail) + Pr (Tom pass and Ben fail)
Pr(only one pass) = (0.8 × 0.3) + (0.7 × 0.2)
Pr(only one pass) = 0.24 + 0.14
Pr(only one pass) = 0.38
