The manager is checking the results of the customer satisfaction surveys. The ones he has looked at have scores of 79%, 92%, 71%, and 86%. What score must be on the next survey to have a mean average of exactly 85% for the five surveys?

Answers

Answer 1

Answer:

97%

Step-by-step explanation:

for such a question we can use the percentage numbers like real unit numbers, as we need to analyze just the percentage numbers and align them with another percentage number with the result of another percentage number.

so, we just use the percentage numbers and deal with mean values and such like with real unit numbers.

therefore we need to find x

(79 + 92 + 71 + 86 + x) / 5 = 85

as the sum of all numbers divided by the number of measurements is the mean value.

and so,

79 + 92 + 71 + 86 + x = 425

328 + x = 425

x = 97

so, the next site must be 97%, so that the average for the 5 surveys will be exactly 85%

Expression sum for 18 and 12 subtracted from 50

Answers

Answer:

50 - (18+12)

Step-by-step explanation:

First write the sum of 18 and 12 in parenthesis. (18+12)

Then you  write 50 - in the beginning of the expression because the sum of (18+12) will be substracted "from"  50.

Not really sure how to solve this

Answers

Okay so you multiply with the 4 outside of the parentheses
2 times 4 is 8
8a
4 times 3 is 12
So 8a^12
B times ^4 it’s just B
4 times 4 is 16

So the answer is B

rounded to the nearest thousandth.

Answers

Answer:

Step-by-step explanation:

Answer as a fraction = 439/937

Answer as a decimal = 0.469

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

Explanation:

He made 439 baskets out of 937 attempts. So we simply form the fraction 439/937. The number of makes or successes is up top, while the number of attempts is at the bottom. The order is important.

Both 439 and 937 are prime numbers. This means the faction 439/937 cannot be reduced. So we leave it as is.

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

You can use a calculator or long division to find that

439/937 = 0.4685

which is approximate. Rounding to the nearest thousandth (i.e. 3 decimal places) will lead us to 0.469

If we were to move the decimal 2 spots to the right, then we convert to percent form and that's roughly 46.9%

Which of the following angles DOES NOT have equal measure when a pair of parallel lines is crossed by a transversal?

Answers

Answer: we might have come across different types of lines such as parallel lines, perpendicular lines, intersecting lines, and so on. Apart from that, we have another line called transversal.                                                                                    

This can be observed when a road crosses two or more roads or a railway line crosses several other lines. These give a basic idea of a transversal. Transversals play an important role in establishing whether two or more other lines in the Euclidean plane are parallel.

In this article, you will learn the definition of transversal line, angles made by the transversal with parallel and non-parallel lines with an example.  

SOOO in English its LM is the transversal made by the parallel lines PQ and RS such that:

The pair of corresponding angles that are represented with the same letters are equal.

If two parallel lines are cut by a transversal, each pair of alternate interior angles are equal. Transversal property 2
