Answer: same. ( 6 degree )
Step-by-step explanation:
According to the question, An angle that measures 6° is drawn on a piece of paper. As you are looking at the angle through a×6 magnifying glass, which means it magnifies by a factor of 6 indeed. The length and the width of the shape may magnify by factor of 6, but the degree measure of the angle will remain the same.
Even if it is magnified by a factor of 100, the measure of the angle you see on the paper when you look through the magnifying glass will remain the same.

1. Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined.
2. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
3. Test the residuals of two other points to determine how well the line of best fit models the data.
4. Use the line of best fit to help you to describe the data correlation.
Answer:
Explained below.
Step-by-step explanation:
The data from the scatter plot is as follows:
Arm Span Height
19.5 25
35.5 35
37.0 39
40.5 40
44.5 45
45.5 50
49.0 49
51.0 55
52.5 47
59.0 60
61.0 58
(1)
Compute the value of slope and intercept as follows:
[tex]\sum{X} = 495 ~,~ \sum{Y} = 503 ~,~ \sum{X \cdot Y} = 23822 ~,~ \sum{X^2} = 23660.5[/tex]
[tex]\begin{aligned} b &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 503 \cdot 23660.5 - 495 \cdot 23822}{ 11 \cdot 23660.5 - 495^2} \approx 7.174 \\ \\m &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 11 \cdot 23822 - 495 \cdot 503 }{ 11 \cdot 23660.5 - \left( 495 \right)^2} \approx 0.857\end{aligned}[/tex]
The equation of the line of best fit is, y = 0.857·x + 7.174.
(2)
The slope of the line represent the rate of change in y caused by one unit change in x.
In this case the slope of m = 0.857 indicates that as the arm span increases by 1 unit the height increases by 0.857 units.
(3)
To perform the Residual Test, simply take two values from the table and interchange the x and y values.
Consider the values: (37, 39) and (51, 55)
Compute the value of y if x = 39:
[tex]y = 0.857\cdot x + 7.174\\=0.857\times 39+7.174\\=40.597\\\approx 40.6[/tex]
The new value of y (40.6) is close to the original value (39.0)
Compute the value of y if x = 55:
[tex]y = 0.857\cdot x + 7.174\\=0.857\times 55+7.174\\=54.309\\\approx 54.0[/tex]
The new value of y (54) is close to the original value (55)
Thus, it can be said that the line of best fit models the data provided.
(4)
The line of best fit is:
y = 0.857·x + 7.174
The slope of the line is positive.
This implies that there is a positive relationship between the two variables.
The formula of slope in terms of correlation coefficient is:
[tex]\text{Slope}=r\times\sqrt{\frac{Var(x)}{Var(x)}}[/tex]
The correlation coefficient is directly proportional to the slope.
This implies that the correlation coefficient is also positive.
Thus, the variables Arm span and Height are positively correlated.

=> x < 4*-2
=> x < -8
6) 8 - 2x ≤ 46
Subtracting 8 from b.s
=> -2x ≤ 46-8
=> -2x ≤ 38
Dividing b.s by -2
=> x ≥ -19
7) -13x+1 ≤ -25
Subtracting 1 from both sides
=> -13x ≤ -25-1
=> -13x ≤ -26
Dividing both sides by -13
=> x ≥ 2
8) [tex]-7 + \frac{x}{3} > -4[/tex]
Adding 7 to b.s
=> x/3 > -4+7
=> x/3 > 3
Multiplying 3 to b.s
=> x > 3*3
=> x > 9
9) -9x-19 ≥ 17
Adding 19 to both sides
=> -9x ≥ 17+19
=> -9x ≥ 36
Dividing both sides by -9
=> x ≤ -4
10) 16 - x > 9
Adding x to both sides
=> 16 > 9 + x
Subtracting 9 from both sides
=> 16 - 9 > x
=> 7 > x
OR
=> x < 7

Step-by-step explanation:
If f(x) = -15x + 3, then f^-1(x) =
Answer:
f^-1(x) is - (x -3)/15
Step-by-step explanation:
f(x) = -15x + 3
To find f^-1(x) equate f(x) to y
That's
y = f(x)
Which is
y = -15x + 3
Next interchange the terms x becomes y and y becomes x
That's
x = - 15y + 3
Make y the subject
We have
-15y = x - 3
Divide both sides by - 15
We get
y = x-3/-15
y = - x - 3/15
Therefore f^-1(x) is - (x -3)/15

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. 50, 100, 150, 200, .
Answer:
50n
Step-by-step explanation:
This problem can be solved using concept of Arithmetic progression(AP)
In AP series
the series increases or decreases by certain number which is called common difference.
common difference d is given by
d= nth term - (n-1)th term
nth term = a + (n-1)d
where a is the first term of the series
thus series can be a , a+d, a+2d, a+3d, a+4d, ...........a + (n-1)d
_______________________________________
Given series
50, 100, 150, 200
a = 50
to find d lets use 3rd term as nth term and 2nd term as (n-1)th term
d = 150 -100 = 50
Thus,
nth term = 50 + 50(n-1) = 50 + 50n -50 = 50n
50n can represent the position of the term of the sequence.
To validate this lets put n = 4
50*4 = 200 which is the same as the fourth term given in the series.
hence our solution is correct.

Explain what is meant by domain and range.
Answer:
Domain are the values of x-coordinates
Range are the values of y-coordinates
Step-by-step explanation:
In the set of ordered pairs {(-2, 0), (0, 6), (2, 12), (4, 18)}, the domain is the set of the first number in every pair (those are the x-coordinates): {-2, 0, 2, 4}. The range is the set of the second number of all the pairs (those are the y-coordinates): {0, 6, 12, 18}.
{(-2, 0), (0, 6), (2, 12), (4, 18)}
Domain: {-2, 0, 2, 4}.
Range: {0, 6, 12, 18}
Answer:
Domain- set of x-values
Range- set of y-values
Step-by-step explanation:
Domain
The domain of a function is the complete set of possible values of the independent variable. The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
When finding the domain:
The denominator (bottom) of a fraction cannot be zero The number under a square root sign must be positive in this section
Range
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values.
How to find the range
The range of a function is the spread of possible y-values (minimum y-value to maximum y-value) Substitute different x-values into the expression for y to see what is happening. Make sure you look for minimum and maximum values of y. Draw a sketch!Which graph is defined by f(x)=x^2+5|x|+6

Since the equation of the graph has a modulus 5|x|. Which can be span to the negative x component and positive x component, the root of the quadratic function will both be at negative x component and positive x component.
Which are 2 and 3 or -2 and -3
Option C is therefore the best graph for the answer to the question.
The graph of function f is shown. Function g is represented by this equation g(x) = 2(2)^x. A. They have different y-intercepts but the same end behavior. B. They have same y-intercepts but different end behavior. C. They have different y-intercepts and different end behavior. D. They have the same y-intercept and the same end behavior
Answer:
G(×)=2(2)^×.Q
Step-by-step explanation:
As per the function, they have different y-intercepts and different end behavior.
To compare with function f, we need to analyze its y-intercept and end behavior. If the y-intercept and end behavior of both functions are the same, the answer would be D. However, if they differ in either the y-intercept or the end behavior, the answer would be either A, B, or C.
The functions f and g have different y-intercepts since the y-intercept of g is 2, whereas the y-intercept of f would be the value of f(0) based on its graph. Additionally, they have different end behavior since function g approaches positive infinity as x increases, while function f appears to approach a horizontal asymptote.
Answer: C. They have different y-intercepts and different end behavior.

D) parallelogram, rectangle
ANSWER QUICK
Answer:
C) quadrilateral, parallelogram, rectangle
Step-by-step explanation:
The figure has four sides, so it is a quadrilateral. The quadrilateral has four right angles and two equal (in length) opposite sides, so it is a rectangle.
All rectangles are parallelograms, because the two opposite sides of a rectangle are parallel.
Option C should be the correct answer.
Based on the shape and the available option, the possible names for a figure here is the quadrilateral, parallelogram, rectangle
What is quadrilateral?Quadrilateral is a type of shape that is closed shape and a type of polygon that has four sides, four vertices, and four angles.
Generally, a Quadrilateral is formed by joining four non-collinear points. The sum of the interior angles of quadrilaterals is always equal to 360 degrees.
In this case, the figure has four sides, so it is a quadrilateral. The quadrilateral has four right angles and two equal (in length) opposite sides, so it is a rectangle.
All rectangles are parallelograms because the two opposite sides of a rectangle are parallel.
Hence, in this case, it is concluded that the correct answer is option C. quadrilateral, parallelogram, rectangle

How many gallons each of 15% alcohol and 5% alcohol should be mixed to obtain 10 gal of 14% alcohol?
How many gallons of 15% alcohol should be in the mixture? _____ gal
Answer:
Step-by-step explanation:
each gallon 15% alcohol
and 5% alcohol
*is this question correct?
Answer:
Step-by-step explanation:
Let x = Gallons of 15% alcohol
y = gallons of 5% alcohol
x + y = 10 gallons
y = 10 - x
15% of x + 5% of y = 14% of 10 gallons
0.15x + 0.05y = 0.14 * 10
0.15x + 0.05 * ( 10 - x) = 1.4
0.15x + 0.05*10 - x * 0.05 = 1.4
0.15x + 0.5 - 0.05x = 1.4
Add like terms
0.10x + 0.5 = 1.4
Subtract 0.5 from both sides
0.10x = 1.4 - 0.5
0.10x = 0.9
Divide both sides by 0.10
x = 0.9/0.1
x = 9
x = 9 gallons
y = 1 gallons

Slope of line A=2/5
We know that , slope of perpendicular line is product of slopes.
i.e. M1 • M2=-1
[tex] m1 = \frac{2}{5} \: \: [/tex]
m2=?
Now,
[tex] \frac{2}{5} \times m2 = - 1 \\ or \: m2 = - 1 \times \frac{5}{2} \\ \: m2 = - \frac{ 5}{2} [/tex]
Therefore, Slope of line B is -5/2.
Hope this helps..
Good luck on your assignment..
