Which associations best describe the scatter plot?
Select each correct answer.
Positive association
Linear association
Negative association
Nonlinear association
Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Time, in years. The vertical axis is labeled Number infected. Points are plotted at (one, one hundred), (two, ninety), (three, seventy-five), (four, sixty), (five, forty-five), (six, twenty-five), (seven, fifteen), (eight, five), (nine, zero).
Answer: Here you go hope this helps
If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.
Slope is = (60-70)/(25-20) = -2
Using the two-point slope form, y – y1 = m(x – x1)
y – 70 = -2(x – 20)
y – 70 = -2x + 40
y = -2x + 110
Step-by-step explanation:
The associate that best describes the scatter plot is the Negative association.
What is an associate?An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:
Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.
Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.
Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line or near to it.
Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.
If we plot the graph of the data points we will see that the trend of the data is negative, therefore, the value of one variable is decreasing with an increase in the value of another.
Hence, the associate that best describes the scatter plot is the Negative association.

Answer:
ST=8.8
SR=15.5
Step-by-step explanation:
ST is the difference between S and T.
that would be 16.3-7.5=8.8
similarly RT is the difference between S and R
That would be 7.5-(-8)=15.5.
Answer:
ST = 8.8
SR = 15.5
Step-by-step explanation:
As the question demonstrates, they're looking for the measure of ST - which means the distance from S to T.
Now to get ST you'll have to subtract the values given on the number line.
T = 16.3
S = 7.5
16.3 - 7.5 = 8.8
ST = 8.8
Moving on with SR, we have the following. We use the same method of differentiation.
S = 7.5
R = -8
7.5 - (-8) = 15.5
SR = 15.5

work out size of angle marked Y
Answer:
56 degrees
Step-by-step explanation:
a straight line is 180 degrees and the angle given is 124 degrees. you just want to subtract 124 from 180
180-124=56
Answer:
y = 56°
Step-by-step explanation:
y and 124 are adjacent angles and supplementary, sum to 180° , then
y + 124° = 180° ( subtract 124° from both sides )
y = 56°

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50¢ price increases.
b(x) = -____x2 + ____x + _____
Answer:
b(x) = -2x² + 7x + 114
Step-by-step explanation:
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
i.e. quantity became 38-4x
Revenue = Price × Quantity

For problems 8-10, find the measures of the unknown third angles.
Answer:
8=58.5 9=125 10=55
Step-by-step explanation:
a triangle equals 180. so by add the angles we do know than subtracting the answer from 180. is our final answer
Answer:
8=58.5°
9= 125°
10= 55°
Step-by-step explanation:
8.) 31.5 + 90 = 121.5 - 180 = 58.5°
9.) 25 + 30 = 55 - 180 = 125°
10.) 45 + 80 = 125 - 180 = 55°
A triangle has sides represented by 7, x, and x−1. If the perimeter is 28, find the length of the longest side.
Answer:
x (11 unit) is the longest side
Step-by-step explanation:
Given:
Sides;
7, x, and x−1
Perimeter = 28
Find:
Longest side
Computation:
Perimeter = sum of all sides
So,
7 + x + (x -1) = 28
2x + 6 = 28
x = 11
So,
x -1 = 11 - 1 = 10 unit
x (11 unit) is the longest side

RQPO is a trapezoid. What is the value of x?
2
63°
(6x + 9°
R
Answer:
18°
Step-by-step explanation:
Find the diagram attached
From the diagram, since the opposite side are parallel, the sum of the adjacent angle is 180 degrees
From the diagram, m<RQP + m<QPO = 180
Given
m<RQP = 6x+9
m<QPO = 63
Substitute
6x+9+63 = 180
6x + 72 = 180
6x = 180 - 72
6x = 108
x = 108/6
x = 18 degrees
Hence the value of x is 18°
