The slope of the given two points (-3, -2) and (-4, -4) is 2.
<h3>
What do we mean by slopes?</h3>
A line's slope, sometimes referred to as its gradient in math is a numerical representation of the line's steepness and direction.
How steeply a line slopes from LEFT to RIGHT is known as its slope.
By splitting a line's rise, or vertical change, by run, or horizontally change, one can calculate a line's slope.
The slope of a line is consistent no difference what two points on the line you choose (it never varies).
So, the slope of the given two points (-3, -2) and (-4, -4) is:
Slope formula: m = y2-y1/x2-x1
Now, put the values and evaluate the slope as follows:
m = y2-y1/x2-x1
m = -4-(-2)/-4-(-3)
m = -2/-1
m = 2
Therefore, the slope of the given two points (-3, -2) and (-4, -4) is 2.

Answer:
0.159 is the probability that the total length after insertion is between 34.5 inch and 35 inch.
Step-by-step explanation:
We are given the following information in the question:
The length of the first piece is normally distributed with mean value 20 inch and standard deviation 0.5 inch.
The length of the second piece is a normal with mean and standard deviation 15 inch and 0.4 inch respectively.
The amount of overlap is normally distributed with mean value 1 inch and standard deviation 0.1 inch.
The lengths and amount of overlap are independent of one another.
Let the total length of PVC pipe be represented by Y.
The sum of two independent normally distributed random variables is normal, with its mean being the sum of the two means, and its variance being the sum of the two variances
Then, Y follows a normal distribution with
Y = Length of first pipe + Length of second Pipe - Overlap
P(total length after insertion is between 34.5 inch and 35 inch)
0.159 is the probability that the total length after insertion is between 34.5 inch and 35 inch.
The percentile rank of a certain score is the score percentages in its frequency distribution that are equal to it or lower that it.
This means that:
<span>Nancy's percentile rank on a science test was 78. this means that Nancy equaled or surpassed 78% of all those who took the test.</span>
Answer:
14 or -22
Step-by-step explanation:
st=18
s=-4
-4+18=14
so t can be at 14
or -4-18=-22
t can be at -22
