Answer:

(1.13, 7.74) and (-4.13, 18.26)

Step-by-step explanation:

This can be solved in two ways:  mathematically and graphically.

<u>Graphing</u>

Plot both lines and find where they intersect.  See the attachment.

The intersection points are (1.13, 7.74) and (-4.13, 18.26)

<u>Mathematical</u>

y + 2x = 10

y = 10 - 2x

y = 3x² + 7x - 4

10 - 2x = 3x² + 7x - 4

3x² + 9x - 14 = 0

Solve this using the quadratic equation:

x = 1.13 and -4.13

Use these two values of x to find y:

y = 10 - 2x

y = 10 - 2(1.13)

y = 7.74

y = 10 -2x

y = 10 -2(-4.13)

y =  18.26

The two points are:

(1.13, 7.74) and (-4.13, 18.26)

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 .
