Answer:
b
Step-by-step explanation:
We need to find the median of:-
73 75 87 65 69 62 81 64 68 101 74 71 89 87
First, we need to arrange the numbers in ascending order as below:-
62, 64, 65, 68, 69, 71, 73, 74, 75, 81, 87, 87, 89, 101
Since there are a total of 14 numbers, let's split it up into two halves (each of seven numbers)
62, 64, 65, 68, 69, 71, 73 ||| 74, 75, 81, 87, 87, 89, 101
The median would be the mean of the two middle numbers i.e. the mean of 73 and 74
Median =
=
= 73.5
So, about half of the students spent less than 73.5 minutes doing homework and about half spent more than 73.5 minutes on homework
Answer:
sqrt(98) aka
Step-by-step explanation:
To find the third side we need to use the Pythagorean theorem (a^2 + b^2 = c^2) so let 3 = a and b = sqrt(89) so a^2 = 9 and for b^2 just ignore the square root so b^2 = 89 then we add 9 and 89 89 + 9 = 98 so c^2 = 98 then we do the square root of 98 since the square root of 98 isn't a whole number/ has a decimal we just leave it written as sqrt(98)
