Answer:
21, 144, 12
Step-by-step explanation:
Given that a sample of 30 distance scores measured in yards has a mean of 7, a variance of 16, and a standard deviation of 4.
Let X be the distance in yard.
i.e. each entry of x is multiplied by 3.
New mean variance std devition would be
E(3x) = 
Var (3x) = 
Std dev (3x) = 
Thus we find mean and std devition get multiplied by 3, variance is multiplied by 9
Answer:
E) 31
Step-by-step explanation:
0 x 2 + 1 = 1
1 x 2 + 1 = 3
3 x 2 + 1 = 7
7 x 2 + 1 = 15
15 x 2 + 1 = 31
So the circle when it is filled in means that the number is included so in the phase the < or > sign will have a line under it, for instance 1. X> 2 the answer would be D because everything that the number line is showing you is less than 2 and the circle is not filled in so 2 is not included in the answer
