Answer:

Option D, \frac{30}{12-6}

Step-by-step explanation:

<u>Step 1:  Determine the correct expression</u>

So we know for sure that we will be doing 12 - 6 because we have the part where it says the difference of 12 and 6.  That leaves us with Options A and D.  Looking back at the statement we can see that the quotient of 30 and the rest which means that 30 would be the numerator and located at the top.  This gives us option D.

Answer: Option D, \frac{30}{12-6}

Answer:

D. \frac{30}{12-6}

Step-by-step explanation:

We can immediately eliminate choices B and C because B shows "the difference of 6 and 12", not "of 12 and 6", and C shows "the quotient of 30 and 12 minus 6." 12 and 6 are not being subtracted properly.

30 is being stated before the difference of 12 and 6, so the difference will be the divisor, and 30 will be the dividend, therefore it will go in the <u>numerator</u>.

The only option that fits this criteria is D, so that is the answer.

hope this helps :)

After 8 points are added to each score in a sample, the mean is found to be M= 40. What was the value for the original mean
MArishka [77]

Answer:

The value for the original mean = 32

Step-by-step explanation:

Here, we want to calculate the original value of the mean.

Let the number of samples be n

Mathematically;

mean = Total value/n

Now, we added 8 to each of values; total value added = 8 * n = 8n

Now, for the new mean of 40; we have

(Total value + 8n)/n = 40

Total value + 8n = 40n

Total value = 40n -8n

Total value = 32n

kindly recall from the beginning of the solution;

mean = Total value/n

mean = 32n/n

mean = 32

So the original value of the mean is 32

The mean of 8 math quiz scores is 88. If the first seven scores are 85,70,92,85,91,100, and 88, what is the eighth quiz score? U
777dan777 [17]

Answer:

93

Step-by-step explanation:

The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.

In this case, representing the eighth score with x, the mean is (611+x)/8

Solving for the mean:

88=(611+x)/8

Multiply both sides by 8

8*88=611+x

704=611+x

704-611=x

x=93
