Answer:
60 degrees.
Step-by-step explanation:
Do you see those red points on the lines? Those red arrows indicate that the lines are parallel, meaning, when there's a line crossing through two parallel lines, are vertical and adjacent angles are the same.
In this case, 11x-6 is equal to 10x.
11x-6 = 10x
-6 = -1x
divide -x both sides, you get x = 6.
Now you know that 11x - 6 = 60, because 11x - 6 = 10x, and since x = 6, 10x = 60.
---------------------------------------------------------------------------------------------------------
Since 10x is on a straight line, the angle next to it adds up to 180, so...
10x + y = 180.
We know that 10x = 60, so 60 + y = 180.
subtract both sides by 60, you get y = 120.
Now, you solved the whole graph.

D. The positive Correlation between the number of shopping carts at a store and the number of cash registers in the store.
Answers
Answer:
C and B
Step-by-step explanation:
in x=5.9x-19.5 the y int is -19.5 (y=mx+b m = slope b =y int)
According to the information they earn 5.9 of something "every payday" and the y int is them starting out. The only logical answer is C for the first question because every other answer involves slope and not starting value.
For the second one it is B i think since causation means cause to effect or ratio. They are the only values that make since because they are related to eachother.
Sorry for the bad spelling if you need any more information please ask in comments :)
The answers of question 1 and question 2 are option C and B respectively.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction
Given equation,
y = 5.9x - 19.5
And we have the slope intercept form
y = mx + b,
where m is the slope and b is the y-intercept.
Comparing above of both the equation,
Here, the y intercept is -19.5 and the slope is 5.9
According to the information they earn 5.9 of something "every payday" and the y intercept is them starting out.
The answer is C for the first question because every other answer involves years that means slope and not starting value.
For the second one,
answer is B i think since causation means cause to effect or ratio.
The positive Correlation between the number of typing classes a student takes and the number of words per minute the student can type.
Relation is directly related to each other.
Therefore, the answers of question 1 and question 2 are option C and B respectively.

A food server records the total bill and the amount of the tip received by 5 individuals who dined alone. Here are the data: Total $4.50 $5.79 $6.25 $4.62 $6.35 Tip $0.75 $1.00 $0.75 $0.58 $1.00 (a) Is there a clear explanatory variable and response variable in this setting? If so, tell which is which. If not, explain why not. b) Make a scatterplot of these data on your work document. (c) Based on the scatterplot, describe the relationship between the total bill and tip received for these 5 customers. (d) The correlation r between the total bill and tip received is r = 0.67. Explain how this confirms the description from part (c). (e) How would r change if all the total bill amounts were reduced by 10%? tip received was measured in cents rather than dollars? (f) Suppose another customer whose total bill was $5.15 tipped $0.75. How would including this point influence r? Justify your answer without performing any calculations.
Answers
Answer:
(a) There is not a clear explanatory variable and response variable
(b) Please find attached the scatterplot created with Microsoft Excel
(c) There is some relationship between the total bill and tip received
(d) The correlation value of r = 0.67, reaffirm that there is an amount of positive correlation between the total bill and the tip received
(e) The correlation will remain positive, and will increase
(ii) The correlation will remain constant
(f) The correlation and r will increase marginally
Step-by-step explanation:
(a) The given parameters are;
Total [tex]{}[/tex] Tip
$4.50 [tex]{}[/tex] $0.75
$5.79 [tex]{}[/tex] $1.00
$6.25 [tex]{}[/tex] $0.75
$4.62 [tex]{}[/tex] $0.58
$6.35 [tex]{}[/tex] $1.00
From the given data, the relationship between the variables are not clear as the lowest and the second highest total give the same amount as tip, the second lowest receive the lowest tip and the median value of the total and the highest value give the same value of tip
Therefore, there is not a clear explanatory variable and response variable
(b) Please find attached the scatterplot
(c) Based on the scatterplot, as the total bill increases, the response the tip increases, therefore, there is some relationship between the total bill and tip received
(d) The correlation value of r = 0.67, reaffirm that there is an amount of positive correlation between the total bill and the tip received
(e) (i)Whereby the total bill were reduced by 10% each, we have, that the correlation will remain positive, and will increase
(ii) Whereby the tip received were measured in cents rather than dollars, the correlation will remain constant
(f) When the total bill of another customer whose bill is $5.15 and tipped $0.75 is added, we have three customers out of six that give an equal tip, therefore, the correlation and r will increase marginally
Creating a linear regression model of the given data, the necessary deductions required to solve the problems posed. Hence, the solutions are as follows :
A.)
The explanatory variable is not very obvious as we have similar measured or predicted value for two different data points in the data.
B.)
The scatterplot of the relationship is attached with Total being the independent and tips being the dependent variable.
C.)
The scatter plot shows a positive association or relationship between total and tips.
D.)
The Correlation Coefficient gives the strength and direction of the relationship between two variables. Hence, 0.67 is positive and shows a fairly strong association.
E.)
A reduction in total bill by 10% would still depict an increase in the tips as based on the total bill amount.
If tips was measured in cent and not dollars, then, the the value of r will remain the same, as the unit of a variable has no effect on the correlation Coefficient.
F.)
The addition of a point with total bill of 5.15 and tip amount of 0.75 will strengthen the existing relationship. Hence, the value of R will increase slightly.

Sam read 6 chapters in 2 hours. If he continues to read at this same rate, how many chapters will he read in 1 day?
Answers
Answer:
He will read 72 chapters in 1 day
Step-by-step explanation:
Let us use the ratio method to solve this question
∵ Sam read 6 chapters in 2 hours
∵ He continues to read at this same rate for 1 day
→ We must change the day to hours
∵ 1 day = 24 hours
∴ We need to find how many chapters he will read in 24 hours
→ Chapter : Hour
→ 6 : 2
→ x : 24
→ By using cross multiplication
∵ x × 2 = 6 × 24
∴ 2x = 144
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{144}{2}[/tex]
∴ x = 72
∴ He will read 72 chapters in 1 day

Determine which of the lines, if any are perpendicular.
Line a passes through (2, 10) and (4, 13).
Line b passes through (4, 9) and (6, 12).
Line c passes through (2, 10) and (4, 9).
Answers
Given:
Line a passes through (2, 10) and (4, 13).
Line b passes through (4, 9) and (6, 12).
Line c passes through (2, 10) and (4, 9).
To find:
Which of the lines, if any are perpendicular.
Solution:
If a line passes through two points, then the slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Line a passes through (2, 10) and (4, 13). So, slope of this line is
[tex]m_a=\dfrac{13-10}{4-2}=\dfrac{3}{2}[/tex]
Line b passes through (4, 9) and (6, 12). So, slope of this line is
[tex]m_b=\dfrac{12-9}{6-4}=\dfrac{3}{2}[/tex]
Line c passes through (2, 10) and (4,9). So, slope of this line is
[tex]m_c=\dfrac{9-10}{4-2}=\dfrac{-1}{2}[/tex]
Product of slopes of to perpendicular lines is -1.
[tex]m_a\cdot m_b=\dfrac{3}{2}\times \dfrac{3}{2}=\dfrac{9}{4}\neq -1[/tex]
[tex]m_b\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1[/tex]
[tex]m_a\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1[/tex]
Therefore, any of these lines are not perpendicular to each other.

Parallelogram R S T U is shown. Angle S is 70 degrees.
What are the missing angle measures in parallelogram RSTU?
m∠R = 70°, m∠T = 110°, m∠U = 110°
m∠R = 110°, m∠T = 110°, m∠U = 70°
m∠R = 110°, m∠T = 70°, m∠U = 110°
m∠R = 70°, m∠T = 110°, m∠U = 70°
Answers
Answer:
B. m∠R = 110°, m∠T = 110°, m∠U = 70°Step-by-step explanation:
The opposite angles of the parallelogram are the same.
From the diagram;
<S = <U and <R = <T
Given
<S = 70°
Since <S = <U, hence <U = 70°
Since the sum of angles in a quadrilateral is 360 degrees, hence;
<R+<S+<T+<U = 360
Since <R = <T, then;
<Y+<S+<T+<U = 360
2<T + 70+70 = 360
2<T = 360-140
2<T = 220
<T = 220/2
<T = 110°
Since <T = <R, then < R = 110°
Hence m∠R = 110°, m∠T = 110°, m∠U = 70°. Option B is correct

What is the slope for 5x+2y=6
Answers
Answer:
The slope is -5/2 as a fraction
or -2.5 as a decimal.
Step-by-step explanation:
First we have to get it into this format y = mx + b
5x + 2y = 6 (subtract 5x on both sides)
2y = -5x + 6 (divide by 2 on both sides)
y = -5/2x + 3
The slope is -5/2 or -2.5
