Answer:
$445
Step-by-step explanation:
Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.
Linear regression represents the relationship between two variables. the value of y depends on the value of x.
x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y
y = 2.1 x + 130
y = 2.1 (150) + 130
y= 445
The company expects $445 in sales
The company expects $445 in sales.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Linear regression line y = 2.1x + 130 predicts sales based on the money spent on advertising.
Now, Linear regression represents the relationship between two variables. the value of y depends on the value of x.
Here, x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y as;
y = 2.1 x + 130
y = 2.1 (150) + 130
y = 445
Thus, The company expects $445 in sales.

Answer:
x> -10
Step-by-step explanation:
in order to find what the value of X is you have to multiply the 5 of the denominator into the -6 which would make -30.
You would then divide by 3 in order to get x by itself and would get -30÷3= -10
therefore the answer should be greater than -10
Hope this helped :)
Answer:
x > -10
Step-by-step explanation:
[tex]\frac{3x}{5} > -6[/tex]
Multiply both sides by 5/3
[tex]\frac{5}{3} * \frac{3x}{5} > \frac{5}{3} *(-6)[/tex]
Reduce Everything
[tex]x > -5*2[/tex]
Multiply
x > -10
In Exercises 27 and 28, find the domain of the function
represented by the graph. Determine whether the
domain is discrete or continuous. Explain.
Question 27
The graph on question 27 indicates that there are three points with the locations such as:
(2, 6)(4, 12)(6, 18)In other words, there are three points that lie on the graph with the x-values such as:
{(2, 6), (4, 12), (6, 18)}
We know that the domain includes the set of x-values.
Hence, the domain of the function is:
Domain: {2, 4, 6}Since the points are not connected between them. In other words, there is not a continuous line.
Thus, the function represented on the graph has a discrete domain.
Question 28
The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).
Since there is a continuous line between the points from x = 0 to x = 7.
Thus, the domain of the line function is:
Domain: {0, 1, 2, 3, 4, 5, 6, 7}As the line segment is a continuous line. Thus, the domain is continuous.

Answer: a = 45°
Step-by-step explanation:
The measure of∠PSR is given: 90°
Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.
The total of all angles in a triangle is 180. So subtract 90, then divide by 2.
180-90 = 90
90/2 = 45
a = 45°
If "b" is supposed to be the measure of ∠SRQ, that is 15° The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15
What's the midpoint of a line segment joining the points (5, –4) and (–13, 12)?
Question 8 options:
A)
(–4, 4)
B)
(9, 4)
C)
(–4, 8)
D)
(4, 4)
Answer:
The midpoint of the line segment is located at (-4, 4).
Step-by-step explanation:
We're given the coordinate points of a line that can help us find the midpoint.
The midpoint formula for a line is written as:
[tex]\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)[/tex]
Additionally, we are given the coordinate points (5, -4) and (-13, 12). We can use these and label them with the (x, y) system so we can substitute them into the formula.
In math, a coordinate pair is written as (x, y). This is where cos = x and sin = y. If we are given two coordinate pairs, we can label them with the (x, y) system but also incorporating a subscript to distinguish the two x-values from each other as well as the y-values. We do this by turning the two x-values into x₁ and x₂ and the y-values follow the same protocol: y₁ and y₂.
Therefore, we can label our two coordinates:
(5, -4)
x₁ = 5y₁ = -4(-13, 12)
x₂ = -13y₂ = 12Now, we can place these values into the midpoint formula and simplify to find our midpoint.
Recall that the midpoint formula is:
[tex]\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)[/tex]
Therefore, let's substitute these values.
[tex]\displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)\\\\\\\big(\frac{5 + (-13)}{2}, \frac{(-4)+12}{2}\big)\\\\\\\big(\frac{-8}{2}, \frac{8}{2}\big)\\\\\\\boxed{(-4, 4)}[/tex]
Therefore, the midpoint of the line segment is located at (-4, 4), which is Option A.
Answer: Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
(x1 + x2)/2 , (y1 + y2)/2)
(5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
So the answer would be A)
(-4, 4)
Explanation:
let ( x,y) be the midpoint of the line segment, then x = 5+(-13) / 2 = -8/2 = -4 and y = -4+(12 ) / 2 = 8/2 = 4, the mid point is ( -4,4)

Evelyn is trying to make extra money on her summer vacation from school. She
works two different jobs, earning $11 per hour washing cars and $13 per hour
clearing tables. How much money would Evelyn earn in a week in which she worked
3 hours washing cars and 7 hours clearing tables? How much money would Evelyn
earn in a week in which she worked x hours washing cars and y hours clearing
tables?
Answer:
Washing Cars: $33
Clearing Tables: $91
Step-by-step explanation: Multiply 11 by 3, and multiply 13 by 7. I hope I helped!
Step-by-step explanation:
for every 1 hour she works she gets 11 dollars washing the cars, so you multiply the number of hours by the amount of money she gets each hour. Like so,
11 x 3 = 33, so 33 dollars from washing cars
next - 13 x 7 = 91 dollars from house cleaning
add together the amount of each so, 33 + 91 = 124, 124 is the answer.

At a party there were 20 more women than men. The men paid Rs 30 each, the women Rs 20 each, and the total receipts 2600. How many men and women were there in the party?
Answer: Number of Men = 44;
Number of Women = 64
Step-by-step explanation:
Let the number of men be x
At a party there were 20 more women than men. This means the number of women = x + 20
Since the men paid Rs 30 each, the women Rs 20 each, and the total receipts 2600. This will be represented in an equation as:
(30 × x) + [20 × (x + 20)] = 2600
30x + 20x + 400 = 2600
30x + 20x = 2600 - 400
50x = 2200
x = 2200/50
x = 44
The number of men = 44
Number of women = 44 + 20 = 64
