A is correct.
to find the average, you add up all three test scores, divide the sum by 3
85≤(83+91+n)/3≤90

multiply 3 to eliminate the fraction: 255≤(174+n)≤270
subtract 174: 81≤n≤96

Answer:

The answer would be 11.3

Step-by-step explanation:

All you have to do is figure out how far one is from the other so from 7.8 I went back to 0 of course the Y coordinate stays the same. So then you get the -3.5 make it a positive so just 3.5 and then add to 7.8 to get 11.3

Hope this helped.

A brainliest is always appreciated.

Answer:

The answer is 12.

Step-by-step explanation:

So one side is 1.5 in. and you need the surface area, just think about it like this there are 6 squares and each has 4 sides correct, so you multiply 1.5 x 4 which that equals 6. So the surface area of one square is 6. There are 6 squares so just multiply 6 by 6 and you have 12. The answer is 12.

How are part-to-part ratios different from part-to-whole ratios?
PolarNik [594]

Answer:

Step-by-step explanation:

Ratios can be of 2 types here:

Part to Part

and

Part to Whole

Part-to-Part ratios give the relationship between 2 distinct things/groups. Such as the ratio of male to female in a class, or ratio of water to sugar in a drink etc.

Part-to-Whole ratios give the relationship between one group/thing to the whole population. Such as the ratio of male to total students in a class, or the ratio of cups of sugar to total cups of drinks etc.

<u>Note:</u> If there are 2 parts in a population, we can essentially write 3 ratios. For example, the ratio of male to female in a class is 4 to 5. So in total there are 4+5 = 9 parts (whole). So we can say:

ratio of male to total population is 4 to 9

ratio of female to total population is 5 to 9

Also,

ratio of male to female (as stated before) is 4 to 5

3 ratios.
