The value of a is 72.74.
<h3>What is Probability ?</h3>
Probability is the study of likeliness of an event to happen.
It is given that
The mean
of the distribution is 70
Standard deviation
is 2
p( x<a) = 0.9147
a = ?
From Z table
For p ( p < 0.9147) , z = 1.37


a = 70+ 2*1.37
a = 72.74
Therefore the value of a is 72.74.

y - 3 = -
(x - 2) ← is in point- slope form
with slope m = -
