The scatter plot shows the relationship between the test scores of a group of students and the number of hours they study in a week.
Part A: What is the group of points labeled N called? What is the point labeled M called? Give a possible reason for the presence of point M.
Part B: Describe the association between students’ test scores and the number of hours they study.
Answers
Answer:
Step-by-step explanation:
m is called an outlier and it is a positive association
Answer:
Part A) Part N.) is called the cluster of the whole chart. Part M.) is called the outlier because it's not with the rest of the group, therefore, it's the outlier of the group.
Part B.)
The association between the students' test scores and the number of hours they've studied is a positive correlation. That means the longer the students spent time studying for their tests... the better grades they got because of it. It's a lot like a cause-and-effect kind of situation.

The perimeter of a rectangle is the same as the
perimeter of a square. If the area of this rectangle
is x^2 + 4x – 21 and the side lengths are integers,
find:
a. the perimeter of the rectangle
b. the area of the square
Answers
Answer:
a. 20
b. 25
Step-by-step explanation:
Let find the side lengths of the rectangle,
We can complete the square.
[tex] {x}^{2} + 4x - 21[/tex]
[tex] {x}^{2} + 4x = 21[/tex]
[tex] {x}^{2} + 4x + 4 = 25[/tex]
[tex](x + 2) {}^{2} = 25[/tex]
[tex](x + 2) = 5[/tex]
[tex]x = - 7[/tex]
or
[tex](x + 7)[/tex]
[tex]x = 3[/tex]
or
[tex](x - 3)[/tex]
This means the perimeter of is
2 times -7 equal 14
2 times 3 equal 6
14+6=20.
The side lengths of the square is equal so each side length will measure 5.
[tex] {5}^{2} = 25[/tex]

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 19)(0,19) and (3, 9728)(3,9728).
Answers
Answer:
y = 19*(8)^x
Step-by-step explanation:
We want to write an equation like:
y = a*b^x
That goes through the points (0, 19) and (3, 9728)
Then, when x = 0, we must have y = 19
Replacing those values in the equation we get:
19 = a*b^0 = a*1 = a
19 = a
Then the equation is:
y = 19*b^x
We also know that when x = 3, y = 9728
If we replace these values in the equation, we get:
9728 = 19*(b)^3
Let's solve this for b.
9728/19 = b^3
512 = b^3
∛512 = b = 8
Then the equation is:
y = 19*(8)^x

The total number of counters is 18.
6 of those are red so there would be 6/18 red counters
Simplified, that is 1/3
a. 1/3
Red counters (6) + Green counters (8)=14
14/18 aren’t blue
b. 14/18
A - 6/18 reduced to 1/3
B - 14/18 reduced to 7/9
Explanation:
A - Add up all the numbers as the denominator (bottom) of your ratio fraction. Then take the number of red counters as the numerator (top) to place on top. You then get 6/18. Both numbers can be divided by 6 to get 1/3.
B - Add up all the numbers as the denominator (bottom) like you did above. Then subtract the total number by the number of blue counters (4). That number is 14 because the total number is 18 and it is your numerator (top). Now you have 14/18 which can both be divided by 2 to get 7/9.
Hope this helps, have a great day :)
What is the measure of LXZW?
850
150°
Y

95
Z
215°
W
30°
Answers
Answer:
so the answer is 95°
Step-by-step explanation:
The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.

The population, P, of Johnstown over a period of t years since the town
was founded can be estimated by P = 5,600e0.0591
In approximately how many years after the town's founding will the
population reach 11,200?
Answers
Answer:
12 years
Step-by-step explanation:
Given that
P = 5,600 e^0.0591
Reaching amount = 11,200
time period = t
We need to find out the time period i.e. t
So,
11,200 = 5,600 e^0.0591t
2 = e^0.0591t
Now take the log on both the sides
ln2 = 0.0591t ln
t = ln2 ÷ 0.059
= 0.693147÷ 0.059
= 11.748
= 12 years
