Answer:
See below
Step-by-step explanation:
Grade is slope = rise / run
a) horizontal distance 1400 ft (run) vertical distance = 40 ft (rise)
40 / 1400 = 2.85%
b) rise / run = 805.58 / 13780 = 5.84%
Z- score is a statistical tool that is used to determine the probability of finding a number or a value under a normal distribution plot. A normal distribution assumes that the mean is equal to zero and that the standard deviation is equal to 1. Using the z-score table, we can find the probability either on the right side or the left side. Using the table hence, we find the probability to the left of the value. The probability that is equivalent to the unknown z should be equal to 0.5 + (0.27/2) = 0.635. 0.5 comes from the assumption that the area under the curve on each side is 50% of the total. The equivalent z score is equal to z = 0.345.
Some examples of additions with integers with 5 terms or more are:
- 20 + 1 + 1 + 2 + 1= 25
- 2 + 1 + 1 + 2 + 1= 7
- 20 + 2 + 1 + 2 + 1= 26
- 20 + 1 + 1 + 3 + 1= 26
- 20 + 1 + 1 + 4 + 1= 27
- 200 + 1 + 1 + 2 + 1= 205
<h3>What is an Integer?</h3>
In mathematics, an integer is a whole number that is used to represent a value and is not a fraction.
Furthermore, we can make the addition of integers as they would increment based on the number they are being incremented with and this has been shown above.

<h3>
Answer: Lower right corner (ie southeast corner)</h3>
In this graph, it is impossible to draw a single straight vertical line through more than one point on the yellow line. Therefore, we conclude that this graph passes the vertical line test, which indicates we have a function.
In contrast, the upper left corner fails the vertical line test. Note the left-most pair of points are vertically stacked together. A single vertical line goes through these two points. So this is one possible way to show the graph does not pass the vertical line test, and thereby making this not a function. The upper right corner and lower left corner has the same idea as the upper left corner, so they aren't functions either.
