A baker knows that the daily demand for strawberry pies is a random variable that follows the normal distribution with a mean of
Elan Coil [88]

The demand that has an 8% probability of being exceeded is 38.1230 .

<h3>What is probability?</h3>

Probability is the aspect of mathematics that focus on the occurrence of a random event.

This is calculated below:

The  normal random variable having the  mean is been given as :

(Mu = 31.8)

The standard deviation is been given as ( sd = 4.5)

Then in making our calculation, we will need to make use of the formular below:

\\Z= (X - Mu) / sd = (X - 31.8) / 4.5

But we know that going with the  probability of 0.08

where  k = 1.4051

P (Z > 1.4051)

k = 1.4051

we can have the expression for  k  as [(X - 31.8) / 4.5]

This can be simplified as:

X  = 4.5 (1.4051) + 31.8 = 38.1230.

Therefore, the  demand that has an 8% probability of being exceeded is 38.1230 .

I really need help with this section
Tpy6a [65]

Looks like you did most of it.

The next step would be setting them equal to 105, like the problem suggests.

5z+3x+7x=105

15x=105

x=7

Then we can plug back in to find the numbers.

5*7=35

3*7=21

7*7=49

35+21+49=105

The three numbers are 35, 21, 49.

Hope this helps.

頑張って!
