You need to calculate the z-scores for (3.0 - 1.7) years and (3.0 + 1.7) years.
Then you use a standard normal distribution table to calculate the required probability.
The formula for finding the z-score is
<span>z=<span><span>X−μ</span>σ</span></span>
I think this is how you solve this
Answer:

If we already know that one side= 39 and the other is 56, a triangle must measure up to 180 so 39+56= 95.180-95= 85 m<c= 85.
to find the scale factor we need to compare the two sides the scale factor is 1/2
Answer:
Step-by-step explanation:
(2-2)/(5+1)= 0/6= 0
y - 2 = 0(x + 1)
y - 2 = 0
y = 2
