Answer:
4 will replace?
Step-by-step explanation:
as 3-2=1
6-4=2
4-1=3
8-2=6
again
3-2=1
so
6-x=2
6-2=x
4
plz mark it as brainliest answer
using the Pythagorean Thereom:
3^2 +4^2 = X^2
9 +16 = 25
x^2 = 25
X = sqrt (25)
x = 5
it would be 5 miles
The variance for the sample is 25
For given question,
We have been given the sample size n = 21
and the sum of squares is SS = 500
We need to find the variance for the sample.
We know that the variance is mathematically represented as,
Substituting given values in the above formula,
= 500 / 20
= 25
So, the variance is 25
Therefore, the variance for the sample is 25

Answer:
D, -8
Step-by-step explanation:
First, let's subtract both sides by 4:
|2x - 3| = 13
We can get two different equations from this:
2x - 3 = 13
and
2x - 3 = -13
So:
2x = 16
2x = -10
x = 8, x = -5
The solution set is {8, -5}
