We are asked to d<span>etermine the area under the standard normal curve that lies to the left of the following z score of 1.57. in this case, we can use the rules of integration as this is related to area under the curve:
</span><span>1/2+1/π * integral of (</span><span> e</span><span>−z^2 </span><span>d</span>z0 from 0 to x/2 where z=1.5
Answer is 0.8665

What do you need help with?
In function notation (f(x)=mx+b) m represents the slope and b represents the y-intercept.
In a straight horizontal line the slope is always 0. This cancels out the 'x' factor so you get f(x)=b.
To find b you simply look at where the line crosses the y-axis. in this case it crosses at 2.
When you plug in the y-intercept you get f(x)=2
Answer:i belive that b is the answer from what i got information wise
