Hello can someone help I dont really think I'm correct.
1 answer:
According to the given number line A is on -7, X is on -2 and E is on 8.
As you can observe in the image below, X is 5 units away from A. At the same time, X is 10 units away from E.
<h2>Therefore, point X is double distant from E as far as it is from A.</h2><em>The ratio of this relation would be 2:1 from E to A.</em>

<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.
