Answer: x=4
Step-by-step explanation:
The perimeter´s formula for this kind of polygons is
The triangle perimeter would be:
(x+2)+(x+3)+(x+3)
And the rectangle:
(x+2)+(x+2)+x+x
For them to have the same value, we should equal them:
(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x
Working with this:
3x+8=4x+4
x=4

Answer:
Variance of the given data = 31.143
Explanation:
Variance,
, where n is the number of observations, μ is the mean and
is the observations made.
Number of observations, n = 7
Mean, μ =
