Find the measure of Arc AC in the figure below. Explain your answer by showing your
steps or explain by writing 2-3 sentences.
PLS HELP!
Answers
Answer: 21
Step-by-step explanation:
arc AC = 2b
3x + 9 = 2(3x - 1.5)
3x + 9 = 6x - 3
solve for x
6x - 3x = 9 + 3
3x = 12
x = 4
substitute in the 2 equations
3 (4) - 1.5 = 10.5
which means that if we substitute in the second equation we should get 21
3(4) + 9 = 21
so arc AC= 21 degrees

A line passes through the points (8, 1) and (6, 7). What is the slope?
Answers
Answer:
-3
Step-by-step explanation:
7-1=6
6-8=-2
A line connects the points (8, 1) and (6, 7). The angle is -3.
What is meant by slope?The slope or slope of a line is a number in mathematics that describes both the direction and slope of a line. Gradients are frequently represented by the letter m.There is no clear reason why the letter m is used for gradients, but it was first used in English by O'Brien (1844), who wrote the equation for a straight line as "y = mx + b."He is also depicted in Tod Hunter's (1888) work, where he wrote "y = mx + c."The slope is calculated by dividing the difference between two (arbitrary) points on a line by the ratio of vertical and horizontal change.Therefore,
Slope (m) = ΔY/ΔX
= 3/-1
= -3
The slope = -3
θ = arctan(ΔY/ΔX) + 180°
=1 08.43494882292°
ΔX = 6 – 8 = -2
ΔY = 7 – 1 = 6
Distance (d) = √ΔX2 + ΔY2 = √40 = 6.3245553203368
Equation of the line:
y = -3x + 25
When x = 0, y = 25
When y = 0, x = 8.3333333333333
Hence, A line connects the points (8, 1) and (6, 7). The angle is -3.

Find the average rate of change of the function between the given values of x.
y = -5x - x2 between 2 and x = 6.
Answers
Answer:
The average rate of change is of -13.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function in an interval [a,b] is given by:
\(A = \frac{f(b) - f(a)}{b - a}\)
In this question:
Between 2 and 6. So
\(f(6) = -5(6) - 6^2 = -30 - 36 = -66\)
\(f(2) = -5(2) - 2^2 = -10 - 4 = -14\)
\(A = \frac{-66 - (-14)}{6 - 2} = \frac{-66 + 14}{4} = \frac{-52}{4} = -13\)
The average rate of change is of -13.

Answers
Answer:
Step-by-step explanation:
During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.
On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.

The length of one side of the equilateral triangle in terms of x is 6x.
To find the length of one side of the equilateral triangle in terms of x, we need to consider the perimeter of both the rectangle and the equilateral triangle.
The perimeter of a rectangle is given by the formula:
Perimeter of rectangle = 2(length + width)
In this case, the length of the rectangle is 7x cm, and the width is 2x cm. Substituting these values into the formula, we have:
Perimeter of rectangle = 2(7x + 2x) = 2(9x) = 18x
We are told that the equilateral triangle has the same perimeter as the rectangle.
Since an equilateral triangle has all sides equal, the perimeter can be calculated by multiplying the length of one side by 3.
Therefore, we have:
Perimeter of equilateral triangle = 3(side length)
Since the perimeter of the equilateral triangle is equal to the perimeter of the rectangle (18x), we can set up the equation:
3(side length) = 18x
Dividing both sides of the equation by 3, we get:
side length = 6x
Hence, the length of one side of the equilateral triangle in terms of x is 6x.

Based on the above output, what is the correct conclusion for the Wilcoxon Signed Rank Test?
a. We do not have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
b. We do not have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
d. We have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
Answers
Answer:
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
Step-by-step explanation:
Pvalue is less than the alpha-level:
If the pvalue is less than the alpha-level, we have that there is sufficient evidence of the hypothesis for the population mean/median/standard deviation we are testing.
In this question:
Pvalue less than the alpha-level, so there is evidence that there is a difference in the population median. This means that the correct answer is given by option C.
The correct conclusion is: c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
The given parameters are:
\(\mathbf{p = 0.04}\) --- the p-value
\(\mathbf{\alpha = 0.05}\) --- the significance value or the alpha level
From the options, we understand that the test parameter is the population median
By comparison, the p-value (0.04) is less than the alpha level (0.05)
When the p-value is less than the alpha-level, then it means that there is enough evidence of the hypothesis for the population parameter that is being tested.
Since the p-value is less than the alpha level, then it means that there is enough evidence to show the difference in the population median.
Hence, option (c) is correct

Find the measure of the angle indicated by 19x+5.
Answers
Answer:
100
Step-by-step explanation:
16x + 19x + 5 = 180 {co-interior angles are supplementary}
Combine like terms;
35x + 5 = 180
Subtract 5 from both sides
35x = 180 - 5
35x = 175
Divide both sides by 35
x = 175/35
x = 5
19x + 5 = 19*5 + 5
= 95 + 5
= 100
Answer:
100⁰
Step-by-step explanation:
co interior angles add up to 180⁰
so l9x+5+16x=180⁰
35x+5⁰=180⁰
35x=180⁰-5⁰
35x=175⁰
Divide both side by the co-efficient of x which is 35
35x/35=175⁰/35⁰
x=5
Now to find the value of 19x+5,we have to substitute any x in it by 5
so 19x+5
