Step-by-step explanation:
<u>Normal Distribution</u>
Gauss Distribution is one of the most widely-used continuous probability distribution to characterize random events. The curve of the function is called the bell curve.
The standard Normal Distribution is a special case where the mean and the standard deviation . The values of the cumulative normal distribution cannot be computed by simple calculations, we must use tables of digital implementations integrated with tools like Excel or any online resource.
The entry for standard normal distribution is a parameter called the z-score, computed like shown below
The values provided in our problem are
Computing z results
By using any of the aforementioned resources, we compute the left-tail probability
We choose the first option 5%
The slope is 2/5. the equation to find the slope is y2 - y1 over x2 - x1.
X - y + x + y = 180
2x = 180
x = 90
2x - 2y = x + y
x = 3y
y = x/3
y = 90/3
y = 30
x - y = 90 - 30 = 60
x + y = 90 + 30 = 120
2x - 2y = 180 - 60 = 120
