The scatter plot shows the relationship between the test scores of a group of students and the number of hours they exercise in a week:
On a grid, Label Hours of Exercise on x axis and Test Scores on y axis. The title of the graph is Test Scores and Exercise. The scale on the x axis shows the numbers from 0 to 10 at increments of 1, and the scale on the y axis shows numbers from 0 to 100 at increments of 10. Dots are made at the ordered pairs 1.1, 12 and 1, 30 and 2.1, 21 and 2.5, 42 and 3.5, 30 and 3.5, 45 and 4, 55 and 5, 45 and 5.5, 60 and 5.5, 70 and 6.5, 40 and 7, 50 and 7.5, 80 and 8, 75, and 8.5, 60 and 9, 75. The ordered pair 9, 15 is circled and labeled as T. All the other points are put in an oval and labeled as P
.
Part A: What is the group of points labeled P called? What is the point labeled T called? Give a possible reason for the presence of point T. (5 points)
Part B: Describe the association between students' test scores and the number of hours they exercise. (5 points)

1.5/ 0.25 == 150/25 ==== 6/16/1 =6 : 1Tell whether the angles are complementary or supplementary. Then find the value of x.
Answers
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.

Answer:
It should be D, [tex]x^4 - 2x^3 + 7x^2 -12x - 4[/tex]
Step-by-step explanation:
Since, the equation given in the question is the factored form of the equation D. It can be solved using FOIL (First Outside Inside Last):
x * x³ = [tex]x^{4[/tex]
x * 7x = 7x²
x * 2 = 2x
-2 * x³ = -2x³
-2 * 7x = -14x
-2 * 2 = -4
This all would add up to ⇒ [tex]x^{4}[/tex] - 2x³ + 7x² + (-14x + 2x) -4
Simplifying the parenthesis further would give the option D as the answer.
To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.
Answers
2) .65 • 60 = 37.2 questions need to be right
3) since she got 42 correct, that is greater than 37.2, so she passed.
OR
1) 42/60 = 0.7
2) 0.7 to a percent = 70%
3) since she got a 70% on the test, she passed.
Step-by-step explanation:
To obtain score of 80% on entire exam means the student have to answer
(80/100)×80 = 64 correct answers
Student have already answered 75% of the first 60 questions correctly meaning
(75/100)×60=45 correct answers from first 60 questions
Remaining correct answers s/he have to answer
64-45=19
So from remaining 20 questions s/he have to answer 19 correct questions that is
20 × (x/100) = 19
x = 19 ×(100/20)
x = 95%

A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut? (I will give brainliest if you answer first)
Answers
Answer:
20 - 10 cm sections can be cut from a pipe of original length 2 m
Step-by-step explanation:
Convert 2 meters to cm:
2 m 100 cm
------ * ---------------- = 200 cm
1 1 m
Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:
200 cm
--------------------- = 20 sections
10 cm/section
20 - 10 cm sections can be cut from a pipe of original length 2 m

4m^2 - 14m - 14m + 49
4m^2 - 28m + 49
Answer: 4m²-28m+49
Step-by-step explanation:
(2m-7)² can be written as (2m-7)(2m-7).
You would have to multiply it out like this:
2m times 2m=4m² (2x2=4 and mxm=m²)
2m times -7=-14m (2x-7=-14 then put a m on it)
-7 times 2m=-14m
-7 times -7=49
The equation would then look like this:
4m²-14m-14m+49
Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:
4m²-28m+49

City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:
4x = 8 + 3y
x − 2y = −3
What was the temperature of City A and City B on that day?
City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.
Answers
Answer:
City A was 5 and city B was 4
Step-by-step explanation:
Use substitution. Move 2y over so you have x=-3+2y
Plug that into 4x=8+3y
4(-3+2y)=8+3y
-12+8y=8+3y
subtract 3y from both sides
add 12 to both sides
5y=20
20 divided by 5
y=4
then youd plug it into the other equation
x-2(4)=-3
x-8=-3
x=5
therefore the answer is A
