Which inequality matches the graph? X, Y graph. X range is negative 10 to 10, and y range is negative 10 to 10. Dotted line on graph has positive slope and runs through negative 3, negative 8 and 1, negative 2 and 9, 10. Above line is shaded. a −2x + 3y > 7 b 2x + 3y < 7 c −3x + 2y > 7 d 3x − 2y < 7
The inequality equation of the given description of the inequality graph is; 3x - 2y < 7
What is the inequality of the graph?Given :
X range is negative 10 to 10, and Y range is negative 10 to 10.
Dotted line on graph has positive slope and runs through points: (-3,-8), (1,-2), and (9,10).
Now, since we know the coordinates through which the graph runs, we can pick two coordinates and use it to find the slope through the formula;
m = (y₂ - y₁)/(x₂ - x₁)
If we pick (-3,-8), (1,-2), we have;
m = (-2 - (-8))/(1 - (-3)
m = 6/4
m = 3/2
We will use formula for equation of a line in point slope form to get;
y - y₁ = m(x - x₁)
y - 10 = (3/2)(x - 9)
2y - 20 = 3x - 27
3x - 2y = 7
Because, above the line is shaded, therefore, the correct inequality matching the graph is 3x - 2y < 7

A sample of the salaries of assistant professors on the business faculty at a local university revealed a mean income of $100,000 with a standard deviation of $10,000. Assume that salaries follow a bell-shaped distribution. Use the empirical rule:
a. Approximately what percentage of the salaries fall between $90,000 and $110,000?
b. Approximately what percentage of the salaries fall between $80,000 and $120,000?
c. Approximately what percentage of the salaries are greater than $120,000?
Answer:
a) 68%
b) 95%.
c) 2.5%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 100,000, standard deviation of 10,000.
a. Approximately what percentage of the salaries fall between $90,000 and $110,000?
90,000 = 100,000 - 10,000
110,000 = 100,000 + 10,000
Within 1 standard deviation of the mean, so approximately 68%.
b. Approximately what percentage of the salaries fall between $80,000 and $120,000?
80,000 = 100,000 - 2*10,000
120,000 = 100,000 + 2*10,000
Within 2 standard deviations of the mean, so approximately 95%.
c. Approximately what percentage of the salaries are greater than $120,000?
More than 2 standard deviations above the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean, so approximately 5% are more than 2 standard deviations from the mean.
The normal distribution is symmetric, which means that 2.5% are more then 2 standard deviations below the mean, and 2.5% are more than 2 standard deviations above the mean, which means that 2.5% of the salaries are greater than $120,000.
Q2. Calculate the area of the shaded region in the figure shown.
40°
12m
10m
Answer:
Area of the shaded area = 60 m^2
Step-by-step explanation:
Remark
I don't think you need the 40 degrees for anything.
Formula
Area of Shaded part = area of the rectangle - area of the triangle
Solution
Area of the Rectangle
L = 12 meters
W = 10 meters
Area = 12 * 10
Area = 120 m^2
Area of the triangle
Area = 1/2 b * h
b = 12
h = 10
Area = 1/2 * 12 * 10
Area = 120/2 = 60
Area of the shaded area
120 - 60 = 60
If a line has a slope of 4 and goes through the point open parentheses short dash 1 comma 1 close parentheses, then the equation for the line in slope-intercept form is ______________.
a.)
y equals short dash 4 x minus 3
b.)
y equals 4 x plus 3
c.)
y equals 4 x plus 5
d.)
y equals short dash 4 x minus 5
You are given the slope = 4 and a point is (-1,1)
The equation of a line is written as y - mx + b where m is the slope and b is the y intercept
Using the slope you now have y = 4x + b
Solve for b by replacing x and y with the values of the point:
1 = 4(-1) + b
Simplify:
1 = -4 + b
Add 4 to both sides:
b = 5
The equation of the line is C.) y = 4x + 5
10. Prime numbers from 1 to 100 are running a restaurant - PRIME SPOT, near a tourist point. On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve?
6 tables are required. Each prime number attender should serve 3 customers each.
The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
All the numbers other than prime numbers are composite numbers.
The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.
Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables
Therefore, 6 tables are required.
Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.
Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.
Thus, each prime number attender should serve 3 customers each.

What is the explanation for the above response?Recall that according to the principle of angle of intersecting secants, (a-b)/2 = c
Where a = ∡RV
b = ∡SU = 37°:
and c = ∠T (the angle between intersecting secants.
Thus, if (a-b)/2 = c, and b = c = 37 degrees, then we can substitute these values into the equation to get:
(a - 37) / 2 = 37
Multiplying both sides by 2 gives:
a - 37 = 74
Adding 37 to both sides gives:
a = 111

A marble statue of height h1metres is mounted on a pedestal. The angles of elevation of the top and bottom of the statue from a point h2metres above the ground level are αandβrespectively. Show that the height of the pedestal is ((h1−h2)tanβ+h2tanα)/tanα−tanβ.
So, the height of the pedestal is ((h1−h2)tanβ+h2tanα)/tanα−tanβ.
To find the height of the pedestal, we can use the concept of angles of elevation. The angle of elevation is the angle between the horizontal line of sight and the line of sight to an object above the horizontal.
From the given information, we know that the angles of elevation of the top and bottom of the statue from a point h2 metres above the ground level are α and β respectively.
We can use the tangent of the angle of elevation to find the height of the object. The tangent of the angle of elevation is equal to the height of the object divided by the distance from the base of the object to the point of observation.
Let's call the height of the pedestal as "h3"
So we can write the following equations:
h1/((h3+h1)-h2)= tan(α)
h1/((h3)-h2)= tan(β)
By solving the above equations we can get the value of h3 which is the height of the pedestal.
((h1−h2)tanβ+h2tanα)/tanα−tanβ
This is the final equation which gives the height of the pedestal.

The CPI was 255.7 in 2019 and 258.8 in 2020. Use the CPI to find the rate of inflation from 2019 to 2020.------------------- The CPI was 130.7 in 1990 and 195.3 in 2005. If the cost of household goods in 2005 was $5,400, use the CPI to find the cost of these same household goods in 1990.
The inflation rate from 2019 to 2020 is 1.21. The goods price in 1990 is $3,614.
From the case, we know that:
CPI 2019 = 255.7
CPI 2020 = 258.8
Inflation 2019 - 2020?
CPI 1990 = 130.7
CPI 2005 = 195.3
Price 2005 = $5,400
Price 1990?
Using the CPI data of 2019 and 2020 we can find the rate of inflation using the formula of:
Inflation = (CPI Y1 - CPI Y0) x 100
CPI Y0
Based on the case, we take:
Y1 = 2020
Y0 = 2019
Then, the rate of inflation from 2019 to 2020 is;
Inflation = (258.8 - 255.7) x 100
255.7
Inflation = 1.21
To find the goods price in 1990, we can use the CPI ratio formula, where:
CPI Y1 = Price Y1
CPI Y0 Price Y0
We take:
Y0 = 1990
Y1 = 2015
The price of goods in 1990 is:
195.3 = $5,400
130.7 Price Y0
Price Y0 = $3,614

c. x≥-9
d. x < 9
e. x ≤ 9
Sketch the graph
Answer:
a. unbounded
e. x ≤ 9
Step-by-step explanation:
The interval means all real numbers less than or equal to 9.
Since all numbers to negative infinity are included, it is unbounded.
a. unbounded
e. x ≤ 9
A sketch looks like a number line with a solid dot at 9 and an line pointing left with an arrowhead at the left pointing left.
Answer:
b. unbounded
e. x ≤ 9
Step-by-step explanation:
Interval notation
( or ) : Use parentheses to indicate that the endpoint is excluded.
[ or ] : Use square brackets to indicate that the endpoint is included.
A bounded interval is an interval that includes both its endpoints.
For the interval (-∞, 9]:
The endpoint -∞ is not included.The endpoint 9 is included.Therefore, the given interval is unbounded.
Inequality notation
< means "less than"> means "more than"≤ means "less than or equal to"≥ means "more than or equal to"Therefore, the given interval is represented by the inequality x ≤ 9.
To sketch the graph on a number line:
Place a closed circle at 9.Shade to the left of the closed circle.To sketch the graph on a coordinate plane:
Plot a solid line at x = 9.Shade to the left of the line.Part 2: Refections follow the directions for each reflection, then list the coordinates of the pre-image and image in the space below.
After following the directions for each reflection the coordinates of image and pre-image are found using the rules. The coordinates of the pre image and image after reflections across x and y axis changes sign of the coordinates.
There a few certain transformation in coordinate plane where we follow a certain set of rules.
Let us say that there is a point A(x,y) in the coordinate plane.
If the point A(x,y) is reflected across the x-axis.
Then the x coordinate will not be affected. But the y coordinate will change it's sign but he value of y coordinate remains the same.
Similarly, If the point A(x,y) is reflected across the y-axis.
Then the y coordinate will not be affected. But the x coordinate will change it's sign but he value of x coordinate remains the same.
So, by following the above two rules, we can find all the point after reflection.
1. Reflecting across Y-axis.
A(2,4) → A'(-2,4)
B(4,4) → B'(-4,4)
C(5,1) → C'(-5,1)
D(1,1) → D'(-1,1)
2. Reflecting across X-axis

Which of the following is the slope of the line passing through each pair of points?
Point 1:(-9, -3)
Point 2:(-7, -5)
Please help me I have a test on this soon and need a better understanding !!!
Answer and explanation: The equation for the slope-intercept form is y=mx+b. M represents the slope and b is y-intercept/when x= 0.
We have to arrange the given equation into the form y=mx+b.
3x+2y=-14, We want to somehow isolate y.
2y=-14-3x, We can move all the terms that don't have y to the right
y=(-14-3x)/2, We can get rid of the 2 by dividing by 2 on both sides
y=-7-(3/2)x, We can distribute the division by 2 to both terms on the right
y=-(3/2)x-7, We can now just rearrange the terms
The equation is now in the form y=mx+b as -3/2 is m and -7 is b. Your answer to the first question is A.
For part B, we can use the equation for part A. We know m or the slope is -3/2 so our answer is also A.
