Please help me with this question. I don’t understand how to do this.
Blizzard [7]

Answer:

133/152

Step-by-step explanation:

The probability of 2 independent events is the product of the individual events.  Independent means the first event has no effect on the probability of the second event.  Since we are replacing the first marble, the first even has no effect on the probability of the second event.  

There are 48 total marbles

Let A = pulling a blue marble

Let B = pulling a red marble

So

P(A) = 14/48

P(B) = 19/48

and

P(A then B) = (14/48)(19/48) = 266/2,304 = 133/1,152

Trevor tutors French for $12 an hour and scoops ice cream for $8 an hour. He is going to work 20 hours this week. At least how m
PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

Let M = total amount of money earned

M = 12x+8y

To make more than $190, the equation is:

190<12x+8y

Since Trevor is going to scoop ice cream for 20 hours, the equation is:

190<12x+8(20), which simplifies to 190<12x+160.

Isolate x to find the amount of hours that Trevor needs to tutor.

190-160<12x

30<12x

30/12<x

2.5<x

Trevor must tutor for more than 2.5 hours to make more than $190.
