Is it subtract by 2? So I think it would be 27,25,23,21, 19
Mean is 
and a standard deviation is 
, then the variable 
.
Use substitution
.
This substitution gives you that 
.
a. For X=130, 
and 
(the decimal value is taken from the Standard Normal Distribution Table).
b. For X=90, 
and for X=110, 
. Then 
(the decimal value is taken from the Standard Normal Distribution Table).
<span>(y-7) = 3/5 (x+25)^2 so the y intercept is -7 and the vertex is 35
</span>
Answer: an = 4n + 1
Step-by-step explanation:
Use the formula an = a1 + d (n - 1) to identify the sequence
