Suppose that the average bill for the drive through of 24 customers at Burger Palace is $14.30. It is known that the population
Mice21 [21]

The standard deviation is a measure of a collection of values' variance or dispersion. The true mean bill for a customer at Burger Palace with 95% confidence is $13.38.

<h3>What is a standard deviation?</h3>

The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

Given that the Sample mean (\overline x) is $14.30, the Sample size(n) is 24 customers, the Standard deviation(σ) is 2.30, while for a 95% confidence interval the Z-score is 1.960. Therefore, the true mean can be written as,

Z = \dfrac{\overline x- \mu}{\frac{\sigma}{\sqrt n}}\\\\\\1.960 = \dfrac{14.30-\mu}{\frac{2.30}{\sqrt{24}}}\\\\\\1.960 = \dfrac{14.3-\mu}{0.47}

μ = 13.3788 ≈ 13.38

Hence,  the true mean bill for a customer at Burger Palace with 95% confidence is $13.38.

Solve the system of equations. x + 3y = −12x + 2y = 6
UkoKoshka [18]

Answer:

x=-3/19

y=39/19

Step-by-step explanation:

the equations can be written as the following system

x+3y=6\\-12x+2y=6

If the second equation is multiplied by 3/2 it will become -18x+3y=9

If that equation is then subtracted with the first you will obtain the following

-19x=3, it means x=-3/19

The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19

If g(x) =4x+2 and f(x) =3x-10 <br><br> find g(f(3))
Leya [2.2K]

Answer:

g(f(3))=-2

Step-by-step explanation:

So we have the two functions:

g(x)=4x+2\text{ and } f(x)=3x-10

And we want to find g(f(3)).

So, let's find f(3) first:

f(3)=3(3)-10

Multiply:

f(3)=9-10

Subtract:

f(3)=-1

Therefore, we can substitute -1 for f(3):

g(f(3))=g(-1)

Now, find g(-1):

g(-1)=4(-1)+2

Multiply:

g(-1)=-4+2

Add:

g(-1)=-2

And we're done!

So:

g(f(3))=-2

Jeremy is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is even} and let B = {the sum of
Roman55 [17]

Answer:

A ∩ B = {12}

Step-by-step explanation:

What are the possible even outcomes?  

Assuming the number cubes are 1-6,

our possible outcomes run from 2-12, but we are looking for even rolls, so A={2,4,6,8,10,12}.  

How many of those are divisible by 3?  B={12}.  

We are looking for what is in common between these, so

A ∩ B= {12}
