There is a probability of 22.66% that their average catch is less than 31.5 pounds

<h3>What is z score?</h3>

The z score is used to determine by how many standard deviations the raw score is above or belaw the mean. It is given by:

z = (raw score  - mean)/ (standard deviation ÷ √sample)

Given that, mean = 32, std = 4, sample = 36, hence:

For 31.5:

z = (31.5 - 32) / (4 ÷√36) = -0.75

P(z < -0.75) = 0.2266

There is a probability of 22.66% that their average catch is less than 31.5 pounds

A number has two digits. The digit at tens place is four times the digit at units place. If 54 is subtracted from the number, th
iren2701 [21]

"The digit at tens place is four times the digit at units place."

How many possible numbers are there?

1 in the units place: 41

2 in the units place: 82

If you try 3 in the units place, 4 * 3 = 12, you'd get 123, and now it's a three-digit number, so the only possibilities are 41 and 82.

41 or 82

If you subtract 54 from 41, you get a negative number, so 41 cannot be the number.

82 - 54 = 28, which has the digits of 82 in reverse order.

Answer: 82

aniked [119]

The combination can be

  • 20 Blueberry, 24 chocolate, 16 strawberry
  • 10 Blueberry, 12 chocolate, 8 strawberry
  • 5 Blueberry, 6 chocolate, 4 strawberry

<h3>What is factor?</h3>

A factor is a number that is multiplied by another number to produce the desired result. The answer to a multiplication puzzle is a product. Imagine multiplying the factors in a multiplication problem to get the answer. For instance, the factors 2 and 4 add up to 8: Just two factors or a great many factors can affect a number.

Total Number of Factors for N = (a+1) (b+1) (c+1) is the formula for the total number of factors for a given number.

given:

Type               Number of muffins

blueberry              40

Chocolate              48

Strawberry             32

So, muffins need to be divided equally into separate gift baskets with the same number of each type of muffins in each basket.

The possible condition can be

2 gift basket

20 Blueberry, 24 chocolate, 16 strawberry

4 gift basket

10 Blueberry, 12 chocolate, 8 strawberry

6 gift basket

5 Blueberry, 6 chocolate, 4 strawberry
