Maria says the mean for the following data set is 5. {5, 7, 2, 8, 9, 1, 2, 5}

What is the actual mean? (Round to the nearest hundredth)

What did Maria do wrong? In other words, what average did she give instead?

Answers

Answer 1

Answer:

4.88

Step-by-step explanation:

I used my calculator to do this;

I did stat and I put in the numbers, I clicked calculate and it said the answer was 4.875. Round that to the nearest hundredth and you'll get 4.88.

Answer 2

Answer:

4.88

Step-by-step explanation:

The actual mean is 4.88 to the nearest hundredth. She either approximated the sum of elements to 40 instead of 39 or she approximated the actual mean to the nearest whole number.

I think she gave an approximated average or a rounded average, but I am not sure.

The total cost of the tent is 409.86

------------------------------------------------------

explanation:

230×0.65=149.50

230+149.50=379.50×.08=30.36

379.50+30.36=409.86

(Hope this helps :) )

Answer:  409.86 dollars

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

Explanation:

65% = 65/100 = 0.65

65% of 230 = 0.65*230 = 149.50

When applying markup, the store increases the cost by $149.50 to get the retail price of 230+149.50 = 379.50, which is the price the customer sees. This is the price before tax.

As a shortcut, we can say 1.65*230 = 379.50 because 1.65 = 1 + 0.65 = 100% + 65%. So 1.65 effectively means "increase the value by 65%"

Similarly, the multiplier 1.08 means "increase by 8%". The cost after tax would be 1.08*379.50 = 409.86 which is the answer

----------

As an even quicker shortcut, we can do both increases at once to say:

1.65*1.08*230 = 409.86

The order of multiplication doesn't matter. The two multipliers 1.65 and 1.08 can be combined into 1.65*1.08 = 1.782 which represents a 78.2% increase overall. After the mark up and tax are considered, the jump from $230 to $409.86 is 78.2%

We can apply the percent change formula to confirm this

A = old value = 230

B = new value = 409.86

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (409.86-230)/230 ] * 100%

C = 0.782 * 100%

C = 78.2%

So it might be tempting to say 65% + 8% = 73%, but as you can see above, that calculation is not true.

math question, evaluation ​

Answers

Answer:

P = 131 degrees

Step-by-step explanation:

We know that the sum of the interior angles of a triangle is 180 degrees

The exterior angles shown form a straight line with the corresponding interior angle

So the two interior angles can be calculated

The sum of two angles on a straight line is 180 degrees

By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180

Thus;

P + (180-162) + (180-149) = 180

P + 18 + 31 = 180

P = 180-31-18

P = 131

An account earns simple interest. Find the annual interest rate. Interest = $60 principle = $500 time = 2 years Please help!!

Answers

Answer:

A = $560.00

Step-by-step explanation:

I = A - P = $60.00

Formula:

[tex]A = P(1 + rt)[/tex]

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 500(1 + (0.06 × 2)) = 560

A = $560.00

The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.

hope this helps you

can I have the brainliest please?

Answer:
JL
Explanation:
To determine the answer, you’d first want to identify the hypotenuse. The hypotenuse of a triangle is the side opposite of the right angle. Therefore, the hypotenuse would be LK, so that can’t be the correct answer.
JK is opposite of L, making it the opposite leg.
This leaves JL as the adjacent leg, since it is not the hypotenuse and it is touching L.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Dave and 6 friends went to dinner.

What is revenue?

Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.

Total Revenue = Number of Units Sold X Cost Per Unit

According to the question

a> The company wants to reduce total expenses to $1,300.

Then expenses would i cut is from

Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.

b>After the decision the impact will be on profit is

It will increase our profit by $1,300 as

Profit = Sales - Expenses  

c>if the company increases prices 20%

i.e

If price will be increases then revenue will also increase by 20%

As  Total Revenue = Number of Units Sold X Cost Per Unit

Therefore ,

Total Revenue = 356500 * 1.2

                         = 427800

d> If the cost of supplies (inputs) decreases,

The impact on profit is it will increase

as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .

e> If the supply of a product goes down,

It will lower the revenue or sales also

as Total Revenue = Number of Units Sold X Cost Per Unit  

But if supply of a product goes down and price per unit  increase it will maintain the sales or revenue  .
