Well, it’s quite surprising to learn that washing and drying may take up to 80 minutes.

It’ll take 5 hours and 26 mins. Here’s how: Turn 2 hours 32 mins into minutes completely: 152 mins. Take that and divide it by the amount of loads (4) to get the number of minutes it takes for each load: 38 minutes. Multiple the mins it takes for each load (38) by 7 to get 266 minutes. Subtract by 60 (because dividing will give you a decimal) to group 266 into hours. You’ll get 5 pairs of 60 with a spare if 26 which means you’ve got 5 hours and 26 minutes.

Answer: you would withdraw $1150

Step-by-step explanation:

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = 1000

R = 3%

T = 5 years

I = (1000 × 3 × 5)/100 = $150

The amount that you would withdraw including principal and interest would be

1000 + 150 = $1150

Assuming that all the grapes have the same probability of being randomly picked:

  • a) 0.11
  • b)  0.24

<h3>How to find the probabilities?</h3>

We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.

a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:

P = 8/23

But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:

P' = 7/22.

The joint probability is the product of the two individual probabilities:

prob = (8/23)*(7/22) = 0.11

b) For the first green grape we know that the probability is:

P = 8/23

Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:

P' = 15/22

Then the joint probability is:

prob = (8/23)*(15/22) = 0.24
