Answer:
A) a small variance for the difference scores and a small standard error
Step-by-step explanation:
Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.
12. find the area between the curve y=x³-2 and the y-axis between y= -1 and y=25
Answer:
m = -1/3
Step-by-step explanation:
a) “6 less than a number”
b) “2 times the quotient of a number and two”
c) “4 times the difference of a number and 8”
When the ball hits the ground, the height is 0.
0 = 100 - 16t²
0 = (10 - 4t)(10 + 4t)
0 = 10 - 4t or 0 = 10 + 4t
4t = 10 or -4t = 10
t = or t =
Time cannot be negative (unless you have a time machine) so disregard
Answer: t = = 2.5 seconds
