Well the variance is how close or far the points are from the mean.. so if it is a large variance then the sample with be very spread out. If your variance is large then your standard deviation is also large.
Answer:
x = 3
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles
∠ QRT is an external angle, thus
∠ QRT = ∠ RTS + ∠ RST, substitute values
45x = 25x + 57 + x
45x = 26x + 57 ( subtract 26x from both sides )
19x = 57 ( divide both sides by 19 )
x = 3
dang this is hard for me, let me think
