Answer:
The value is ![P( 1.39 < z < 1.53 ) = 0.0193](https://tex.z-dn.net/?f=P%28%201.39%20%3C%20%20z%20%3C%20%201.53%20%29%20%3D%200.0193)
Step-by-step explanation:
From the question we are told to obtain the area to the of the z-score 1.39 and to the left of the z-score 1.53, this is mathematically represented as
![P( 1.39 < z < 1.53 ) = P( z < 1.53 ) - P( z < 1.39 )](https://tex.z-dn.net/?f=P%28%201.39%20%3C%20%20z%20%3C%20%201.53%20%29%20%3D%20%20P%28%20z%20%3C%20%201.53%20%29%20-%20P%28%20z%20%3C%20%201.39%20%29)
From the z table on the question the area under the normal curve to the left corresponding to 1.53 and 1.39 is
![P( z < 1.53 ) = 0.9370](https://tex.z-dn.net/?f=P%28%20z%20%3C%20%201.53%20%29%20%20%3D%200.9370)
and
![P( z < 1.39 ) = 0.9177](https://tex.z-dn.net/?f=P%28%20z%20%3C%20%201.39%20%29%20%20%3D%200.9177)
So
![P( 1.39 < z < 1.53 ) = 0.9370 - 0.9177](https://tex.z-dn.net/?f=P%28%201.39%20%3C%20%20z%20%3C%20%201.53%20%29%20%3D%200.9370%20-%200.9177)
=> ![P( 1.39 < z < 1.53 ) = 0.0193](https://tex.z-dn.net/?f=P%28%201.39%20%3C%20%20z%20%3C%20%201.53%20%29%20%3D%200.0193)
Answer:
y=4x
Step-by-step explanation:
y=mx+b is our frame equation for a linear function.
b=the y intercept, or when the line crosses the y axis, whenever x=0, so in this chart it is (0,0), b=0
y=mx+0
m= the slope, to find m you can either use the slope formula or plug in a point and solve for m
8=m(2) + 0
m=4
we don't need to put 0 in our final answer because it doesn't change anything
