Luke receives an electric bill of \$84.21$84.21dollar sign, 84, point, 21 for the month of April. The electric company charges \$0.14$0.14dollar sign, 0, point, 14 per kilowatt-hour (\text{kWh})(kWh)left parenthesis, start text, k, W, h, end text, right parenthesis of electricity. Given that April has 303030 days, about how many kilowatt-hours did Luke use per day during the month of April?

Answers

Answer:

20.05 kilowatt-hour

Step-by-step explanation:

Total electric bill = $84.21

Charges per kilowatt-hour = $0.14

Days in April = 30 days

Number of hours = x

Total electric bill = Charges per kilowatt-hour × Days in April × Number of hours

84.21 = 0.14 * 30 * x

84.21 = 4.2 * x

84.21 = 4.2x

Divide both sides by 4.2

x = 84.21 / 4.2

= 20.05

x = 20.05 kilowatt-hour

Therefore, Luke use 20.05 kilowatt-hour per day during the month of April

By how much does the outlier in the following data set increase the mean of the data set? Round your answer to the nearest hundredth if necessary.
{10, 12, 17, 18, 22, 30, 101}

I NEED THIS ANSWERED BEFORE 10 PM PST

Answers

Answer:   11.83

=======================================================

Explanation:

With the outlier, the mean is

m = (10+12+17+18+22+30+101)/7 = 30

I added up the values and divided by 7 since there are 7 values being added up.

Without the outlier 101, the mean is now

n = (10+12+17+18+22+30)/6 = 18.1667 approximately

We're dividing by one less item this time.

Subtract the values of m and n

m-n = 30-18.1667 = 11.8333

This rounds to 11.83

The large outlier 101 increases the mean by roughly 11.83

Any time the outlier is larger than the main cluster of values, the mean is pulled to be larger than it should be if we ignored the outlier. The further the outlier, the stronger the pull and the more skewed the mean will get.

Note how the median of {10,12,17,18,22,30} is 17.5 which is a better measure of center compared to m = 30 found earlier.

Answers

If you are trying to find the cost of the basket ball, it is $8.15.

Step 1: Find 20% of 10.95- which is 2.19- and subtract 2.19 from 10.95-which is 8.76.

Step 2: Find 7% of 8.76-which is 0.6132- and subtract 0.6132 from 8.76-which is 8.1468

Step 3: Round to the nearest hundredth, which gives you 8.15.

Thus, $8.15 is your answer.

is the answer I hope this helps $8.15

Step-by-step explanation:

A well-detailed version of the question has been uploaded in form of an image for easier understand.

Looking at the question, it was said that she received her store order on 12/3/2016 at 4am, this implies that the prep date and time are 12/3/2016 and 4am respectively. Also, it was said that the expiration date was printed on the product and it is 1/17/2017. Obviously, the expiration time would also be 4am because it was prepared at 4am and if we calculate in. 24hours we would get 4am at the expiration date as well. Lastly, we were told she opened the product she received on 12/7/2016 which is the initial date the product was used. From all these we can deduce the following:

Exp Date: 1/17/2017

Exp Time: 4:00am

Which expression is equivalent to 10 - 6(5 - 2y)?

Answers

Answer:4(-5+3y) or -20+12y

Step-by-step explanation:

Order of operations states you have to distribute -6 to (5-2y) before you subtract anything from 10.

-6(5-2y) = -30 + 12y

10 - 30 + 12y = -20 + 12y

You can factor out a 4 now.

The function LaTeX: f\left(x\right)=-x^2+4f ( x ) = − x 2 + 4 defined on the interval LaTeX: -8\le x\le8− 8 ≤ x ≤ 8 is increasing on the interval LaTeX: \left[A,B\right][ A , B ] and decreasing on the interval LaTeX: \left[C,D\right][ C , D ]. Fill in the blanks below.

Answers

Given:

The function is

[tex]f(x)=-x^2+4[/tex]

It defined on the interval -8 ≤ x ≤ 8.

To find:

The intervals on which the function is increasing and the interval on which decreasing.

Step-by-step explanation:

We have,

[tex]f(x)=-x^2+4[/tex]

Differentiate with respect to x.

[tex]f'(x)=-(2x)+(0)[/tex]

[tex]f'(x)=-2x[/tex]

For turning point f'(x)=0.

[tex]-2x=0[/tex]

[tex]x=0[/tex]

Now, 0 divides the interval -8 ≤ x ≤ 8 in two parts [-8,0] and [0,8]

For interval [-8,0], f'(x)>0, it means increasing.

For interval [0,8], f'(x)<0, it means decreasing.

Therefore, the function is increasing on the interval [-8,0] and decreasing on the interval [0,8].
