Billing charges for Microsoft 365 Commercial licensing. When a customer purchases a subscription and changes the amount during the subscription period, a full refund is credited then prorated for what was used. For example, if a customer purchased 2 subscriptions for the month of June at $15 each, the total charge for the month would be $30. If they decide to return one subscription 5 days later, the full $30 would be credited then a prorated charge for what was used would be applied. Credit $30 Charge $15 Charge $0.5 * 5 = $2.50 $15 / 30 = $0.5 p/day Total Charge $17.50 Total Credit $12.50 If a customer purchases 10 Microsoft 365 Business Premium licenses at $22 each per month, for a full year then 6 months later decides they only need 5 licenses for the remainder of the year, what would be the total charge and credit for the year?

Answer:

Step-by-step explanation:

Answer:

John = 14 ; Van = 26

Step-by-step explanation:

V = 12 + J

V - 2 = 2(J-2)

12 + J - 2 = 2J - 4

J + 10 = 2J - 4

2J - J = 10 + 4

J = 14

V = 12 + 14

V = 26

To determine how much data is enough to estimate the average weight of this population with a 95% confidence and an error not superior to 15 grams, we would need to use a statistical sample size calculator or consult a statistical table. Factors that would need to be considered include the desired confidence level, the desired margin of error, and the standard deviation of the population.

Using a sample size calculator, we can input these values and determine the required sample size. For example, with a 95% confidence level, a margin of error of 15 grams, and a standard deviation of 87 grams, the required sample size would be approximately 38 children. This means that we would need to measure the weight of at least 38 male children who are 10 weeks old in order to estimate the average weight of the population with a 95% confidence and an error not superior to 15 grams.

It is important to note that this is just an estimate and the actual sample size may vary depending on the specific characteristics of the population being studied. Additionally, it is always a good idea to consult with a statistician or other expert to ensure that the appropriate sample size is used in any statistical analysis.

Answer: z=3x+1

Step-by-step explanation:

1. Distribute 6 through the parentheses

18x=6z-6

2. Move the z variable to the left side and x variable to the right

-6z= -6-18x

3. Divide both sides by -6 in order to get z by itself

z=1+3x

4. Reorder the terms using commutative property

z=3x+1

Answer:

x = 222:2 and x = 2

Step-by-step explanation:

(2x-123):3=33

(2x – 123):3 = 33

2x – 123 = 33.3

2x – 123 = 99

2x = 99 + 123

2x = 222

x = 222:2

x = 111

200-8.(2x+7)=112

200 – 8.(2x + 7) = 112

-8.(2x + 7) = 112 – 200

-8.(2x + 7) = -88

2x + 7 = (-88):(-8)

2x + 7 = 11

2x = 11 – 7

2x = 4

x = 4:2

   x = 2

Answer: A residual is the difference between the observed value of a dependent variable and the predicted value based on a given model. In this case, the manager of the water park has produced a least squares regression equation of the form y = -3110 + 51.2x, where y is the number of customers entering the park and x is the daily high temperature. This equation can be used to predict the number of customers based on a given temperature.

On the day in question, the high temperature was 93F and 1700 customers entered the park. Using the given equation, we can predict the number of customers that would be expected based on this temperature:

y = -3110 + 51.2x

= -3110 + 51.2 * 93

= -3110 + 4768.6

= 1658.6

The residual for this observation is the difference between the observed value of 1700 and the predicted value of 1658.6, which is 1700 - 1658.6 = 41.4. This is the residual for this observation.

The equation of the cubic polynomial is f(x) = x³ - x² -9x + 9.

What is a polynomial function?

Polynomial functions are defined for all values of x and have a finite number of roots (x-values at which the function is equal to 0). The roots of a polynomial function can be found by solving the equation f(x) = 0.

By using the given table, we can plot the points on the graph and we can draw a graph

• Fitted coefficients:

a = 9

b = -9

c = -1

d = 1

Then we can prepare the polynomial as

y = 9 - 9x - x² + x³

Now write down in the standard form, we get

f(x) = x³ - x² -9x + 9

Hence, the equation of the cubic polynomial is f(x) = x³ - x² -9x + 9.

The change represents growth and rate of increase is 4.2%

Exponential functions model a relationship in which a constant change in the independent variable gives the same proportional change.

Given that, an exponential function y = 970(1.042)ˣ

When the growth rate is greater than 1, then the function represents a growth.

The general form equation is:

y(x)= a(1+r)ˣ such that r is the growth percent.

So,

1+r = 1.042

r = 0.042

r = 4.2%

The equation represents that, Miles could rent the meeting room for t ≤ 16 hours.

What is inequality?

The word inequality means a mathematical expression in which the sides are not equal to each other. Basically, an inequality compares any two values and shows that one value is less than, greater than, or equal to the value on the other side of the equation.

The total cost for Miles to rent the meeting room for t hours is given by the equation C = 21 + 4t. We are trying to find the number of hours t for which C is equal to or less than $85.

We can solve this problem by setting up the inequality 21 + 4t ≤ 85 and solving for t.

Subtracting 21 from both sides gives us 4t ≤ 64.

Dividing both sides by 4 gives us t ≤ 16.

Thus, Miles can rent the meeting room for t hours, where t is less than or equal to 16. This means that he can rent the room for 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16 hours.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data

Given that Mary wishes to estimate the mean height of women aged 18-24.

Women aged between 18 and 24 and constructs a 99% confidence interval for the population mean.

If Mary were to repeat this procedure 200 times in total, she would obtain

200 different confidence intervals.

A confidence interval of a parameter gives an interval in which the parameter is expected to be found. Because the interval either contains or doesn't contain the parameter, the probability is either 0 or 100%, which is not helpful.  A 95% CI says that if we construct 100 intervals, 95% will contain the parameter. That is a true percentage, not a confidence. We don't know which 95, however, since the parameter is still unknown or unknowable.

Since  s = (15 - 2πr ) / 4 and s > 0, the maximum r is 15/(2π).  This same r will also maximize the area.

Since the length of 15 is divided between the circumference of the circle and the perimeter of the square,

2πr + 4s = 15 ⇒ s = (15 - 2πr ) / 4

A = πr2 + s2 = πr2 + [ (15 - 2πr ) / 4]2 = πr2 + (225 - 60πr + 4π2r2) / 16

A = π(1 + π/4)r2 - (15/4)πr + 225/16

dA/dr = 2π(1 + π/4)r - (15/4)π = 0 ⇒ r = (15/4)π / [2π(1 + π/4)] = 15 / (8 + 2π)

Since A(r) is concave up, it has a minimum at
