Based on the distance formula, the distance between points (3, 7) and (x1, y) is: 
. SO, it is TRUE.
<h3>What is the Distance Formula?</h3>
The distance formula which can be applied to find the distance between two coordinate points is: 
.
Given the points:
(x1, y1)
(3, 7) = (x2, y2)
Substitute
Therefore, the statement that says the distance between points (3, 7) and (x1, y) = , is TRUE.

A) Mean - add numbers of animals, and then divide by the number of students.
numbers of animals =1*20+2*11+3*18+4*10+5*3 +6*18 = 259
number of students = 20+20+11+18+10+3+18 = 100
mean=numbers of animals /number of students = 259 / 100=2.59
b) median
You can write 20 zeroes, 20 ones, 11 twos and so on. and the remove from left and right equal amount of number, when you get in the middle,it is going to be median
<u>20 "0", 20 "1", 11 "2"</u>, <u>18 "3", 10 "4", 5 "3", 18 "6"
</u> 51 place 51 place
From the left 20+20+11=51 places
18+5+10+18=51 places
We can see that no single middle number. In the middle is going to be two numbers 2 and 3, and divide them by 2.
(2+3)/2=2.5 median
3) (127/151)*100%≈ 84.11%
Cause it’s -$75 he would have to put $75 to achieve a balance of $0
Answer:
There is no solution.
