There are 20 students in the class.
Answer:
The standard error of the mean = 5.14 mins
Step-by-step explanation:
Number of random sample (n) = 20
Mean(X) = 31.25 mins
Standard deviation (α) = 23.7 mins
Standard error of mean =
standard deviation / √sample size
= 23.7/√20
= 23.7/4.4721
= 5.14 mins
They are two triangles faces that are (6x2)/2 = 6 and the other one is 6 to
so that's 12
the top side is 4 x 2 = 8
back side is 3 x 2 = 6
the bottom side is 2 x 6 = 12
so its 12 + 8 + 6 + 12 = 36 inches squared surface area
Answer:
-1/4
Step-by-step explanation:
We can find the slope of a line given two points by using
m = (y2-y1)/(x2-x1)
= (-2- -1)/( -4 - -8)
= (-2+1)/(-4+8)
= -1/4
