79.6 is the mean of given set of scores calculated by adding all the given scores and dividing it by number of scores which is 10.

To find the mean (average) of a set of scores, you need to add up all the values and then divide by the total number of values.

Let's calculate the mean of the math test scores you provided:

Math test scores: 92, 52, 80, 54, 75, 62, 78, 78, 95, 80

Add up all the scores:

92 + 52 + 80 + 54 + 75 + 62 + 78 + 78 + 95 + 80

= 796

Find the total number of scores:

There are 10 scores in the set.

Calculate the mean:

Mean = Sum of scores / Total number of scores

Mean = 796 / 10

Mean = 79.6

So, the mean of the math test scores is 79.6.

Answer: 6 inches = 15.24 cm length

8 inches = 20.32 cm width

24 inches = 60.96 cm height

The diagonal along the side of the box = 20.32^2 + 60.96^2 = 4,129.024

square root (4,129.024) = 64.257 so the rod will fit diagonally.

D.Saturday 8:40am

Step-by-step explanation:

one hour(100) makes 60 minutes

100-60=40

Therefore the answer is Saturday 8:40am

Answer:

44.44 mph

Step-by-step explanation:

Since we are given 50 from the start, and 40 at the end, we will add 50 and 40.

50 + 40 = 90

Then, Divide the result by 2.

90 ÷ 2 = 45

Here is the tricky part: we are not done!

Don't be mistaken by the question. Some people may think the answer is 45mph because that is what it is rounded up, however, the question did not ask for the answer rounded up.

This is a round trip, so reduce this to the nearest value in both tenths and units. Hence, it would be 44.44.

Answer:

m>8

Step-by-step explanation:

The first step will be to distribute the 2, so that the equation becomes 2m + 6 + 1 > 23.

From here we should combine like terms, which just means adding 6 and 1, so that the equation is now 2m+7>23. Now, we just subtract 7 on both sides, which brings leave us with 2m > 16.

Lastly dividing by 2 on both sides, the answer is m>8

Answer:

$8553.87

Step-by-step explanation:

Formula = Initial amount x (1+(%/100) squared by (t) years or time.

7600 x 1.03^4 =8553.86696 = $8553.87 nearest penny rounded up.

To reverse such amount if given percentage (%) time (t) and (nv) new value to question. We realise it has asked the opposite in asking to find the initial investment it may say what Did Dan initially or originally invest? we would divide new amount by (1+) (%/100)^(t) and percentage and show like this;

8553.87 / 1.03^4= 7600.0027  = $7200 for initial investment.

However the question asks for total new value of investment after 4 years.

So the first formula is shown and shows answer to be  $8553.87
