Describe, step-by-step how to find the slope of a line through two points
Answers
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
The equation used to calculate the slope from two points is: m= y2 - y1 / x2 - x1
Example
Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?
Step One: Identify two points on the line.
In this example we are given two points, (15, 8) and (10, 7), on a straight line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).
Step Three: Use the equation to calculate slope.
Once we've completed step 2, we are ready to calculate the slope using the equation for a slope:

Otis measured the heights of several sunflowers. He found that their heights were 2,3,5,7, and 8 feet. Otis found that the mean was 5 feet and the range was 6 feet. Which numbers describe the center and spread of this data set? A. 6 feet describes the center, and 5 feet describes the spread. B. 8 feet describes the center and 2 feet describes the spread C. 5 feet describes the center, and 6 feet describes the spread D. 2 feet describes the center and 8 feet describes the spread.
Answers
Answer:
c
Step-by-step explanation:
The solution is : 6 feet describes the center, and 9 feet describes the spread
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
here, we have,
The center of a data set is mostly considered as the median or the mean
Here mean is 6 (given). And median is also 6.
As 6 is exactly at the middle of the data set. (When arranged in ascending order)
Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.
Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.

Find the area of the following shape
Answers
Answer:
180mm^2
Step-by-step explanation:
CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm
CB is 16mm
the area of the triangle is A=ab/2
A=45mm^2
Now you need to find the area of the rectangle
A=l×w
A= 15×9= 135mm^2
now add both areas
(135+45)mm^2=180mm^2

PLEASE HELP QUICK I DON'T KNOW HOW TO DO
Answers
Answer:
1. 2
2. 30
Step-by-step explanation:
1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)
so q(x) = -3x - 4
(q °p)(x) = -3 (-2x+4) -4 sorry I can't find the actual circle thing symbol
now distribute to get the simplified equation:
= 6x -12 -4
= 6x - 16
because you're doing (q - p )(3), you would plug 3 for x into the new equation
6(3) - 16 = 2
and thats you're answer for the first one
for the second one its the other way around, so you're putting all of q(x) into p(x)
take p(x) : -2x+4
and now replace the x with the entire q(x)
so (p - q)(x) = -2 (-3x-4) +4
simplify: = 6x+8+4 = 6x+12
so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation
= 6(3)+12 = 30
lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)

Write the equation of the line in slope-intercept form using y=mx+b
Answers
Answer:
y = -1/2x -7
Step-by-step explanation:
. The slope of the line (rise over run) goes down so it's negative and it you go down (bc it's negative slope) 1 and go over 2 so it would be -1/2
. B stands for the y intercept so it would be -7 because the line goes through -7 on the vertical line.
