Answer:

Any number above 85.6

Step-by-step explanation:

To calculate the mean you add all of the scores together then divide by how many scores you added

So in this case you would add 84 + 72 + 90 + 87 + 95 = 428

Then you would Divide 428 by five because you are adding 5 numbers

428/5 = 85.6

It says the score increased so as long as then score is greater than 85.6 it is an option.

what is the volume of the rectangular prisms with a length of 1 5/8, a width of 3/8, and a height of 3in
SVEN [57.7K]

Answer:

To find the volume of a cube one must multiply all three dimensions together. Here we know two of the dimensions and the volume but not the third dimension. First I multipl together to two known dimensions: 3/4 x 1/2 = 3/8. Next I divide the volume by this answer by using the reciprocal of 3/8 and multipling. 21/32 x 8/3 = 7/4 by cancelling the 32 with the 8 and the 21 with the 3. Now 7/4 must be changed into a mixed number. Divide the numerator by the denominator and write the remainder as a fraction. 7/4 = 1 3/4.
