Answer this multiple choice question correctly for 40 will give brainliest.

Step-by-step

We know that the square root of 16 is 4.  

15 is one less than 16.

We also know that the square root of 9 is 3.

15 is 6 more than 9.

So by logic, we conclude that the square root of 15 is much closer to 4 than 3.  So answer would be L, which is a touch less than 4.

If we want, we can actually get a very good estimate of the square root of 15, no paper, no calculators, as follows.

Our estimate is 4 (because 4^2=16, ONE more than 15).

Our BETTER estimate is 4- ONE/(twice our estimate)

= 4 - 1/8

= 3.875

(actual value 3.87298.. to 5 decimal places)

The approximate value of \sqrt() 15 is represented by the letter.

L is the approximate value.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
