The revenue from store1 is more. The correct option is A.
What is a scatter plot?A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.
As per the given Scatter plot the revenue for a store can be calculated by adding the revenue collected by the shop from each particular product.
And to calculate the revenue collected by the store from each particular product, multiplying the cost of a single item to its corresponding price.
Therefore, the revenue from each of the store are:
The revenue collection for store1 is $35,100.
The revenue collection for store2 is $29,800.
Since 35,100>29,800, therefore, the revenue from store1 is more.

Web flixs charges $25 and $2 for each movie family video charges $10 plus $2.50 for each movie find the number of movie rental for both stores charge are the same
Answers
To find the answer you have to do this
(M stands for movies)
$25 + 2m = $10 + 2.50m
-10 -2m -10 -2
$15 = .50m
Divide .50/15
You get 30
Check your answer $25 + 2(30) = $10 + 2.50(30)
$25 + $60 = $10 + $75
$85 = $85
The number of movie rentals for which Web Flixs and Family Video charge the same is 30.
Explanation:To find the number of movie rentals for which Web Flixs and Family Video charge the same, we need to set up an equation and solve for the number of movies. Let's denote the number of movie rentals as 'x'.
For Web Flixs, the cost is $25 + $2 per movie, so the total cost can be expressed as 25 + 2x.
For Family Video, the cost is $10 + $2.50 per movie, so the total cost can be expressed as 10 + 2.50x.
To find the number of movie rentals for which the costs are the same, we set up the equation: 25 + 2x = 10 + 2.50x.
By rearranging the equation and solving for 'x', we can find the number of movie rentals:
25 - 10 = 2.50x - 2x
15 = 0.50x
x = 30
Therefore, when the number of movie rentals is 30, the charges at both Web Flixs and Family Video will be the same.

The product of the two numbers whose sum and difference is 83 and 13 respectively is 1680.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is that the sum of two numbers is 83 and the difference of these two numbers is 13.
Assume that the numbers are [x] and [y] respectively. Then -
x + y = 83 ...[1]
and
x - y = 13
x = 13 + y
Substitute (x = 13 + y) in Equation [1], we get -
13 + y + y = 83
2y = 70
y = 35
Therefore, [x] will be equivalent to -
x = 13 + 35
x = 48
Now, the product of [x] and [y] will be -
xy = 35 x 48 = 1680
Therefore, the product of the two numbers whose sum and difference is 83 and 13 respectively is 1680.

Answers
420/10= 42
42 words per min

Answer-
At this rate Sam will be able to type 7,560 words in 3 hours.
Sam can type 7,560 words in 3 hours if he continues typing at the same speed that is 420 words in 10 minutes.
Explanation:The problem is asking to find out how many words Sam can type in 3 hours if he continues at the rate of typing 420 words in 10 minutes. First, we need to convert 3 hours to minutes since the typing speed is given in terms of minutes. There are 60 minutes in an hour, so 3 hours equals 180 minutes. Typing speed is calculated by dividing the total number of words by the total time. In this case, Sam's typing speed is 420 words / 10 minutes = 42 words per minute. Considering his typing speed, in 180 minutes (3 hours), he should be able to type 42 words per minute * 180 minutes = 7560 words. Therefore, the correct answer is D.7,560.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. For each salesman, write an equation showing the relationship between their weekly paycheck amount, p, and the number of sales, s, they had that week. Graph the three equations you just wrote for each salesman if they have between 0 and 20 sales in a week. Graph all three equations on the same graph . Make sure you label each line with the salesman it represents, as well as label the axes. Note: The independent variable is s, and the dependent variable is p.

Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
Salesman A: 1300 ≤ 65S
Salesman B: P = 40S + 300
Salesman C: P = 900
Salesman A can only have 20 sales. 1,300/65 = 20. It should not go beyond that because it will go beyond the limit of 1,300 per week.
Salesman B will earn 1,100 for 20 sales. P = 40(20) + 300 = 800 + 300 = 1,100.
Salesman C will earn 900 regardless if he had 0 or 20 sales for the week.

x + 0 = -4
x = -4
For the y axis:

Substituting in the equation:
x + 2y = -4
0 + 2y = -4
y = -4 / 2
y = -2

please help. ive been on this problem for almost an hour now
Answers
Note: the slope is 1/3 and the y intercept is 1/3
------------------------------------------------------
Explanation:
First we need the slope of the line through the two points. Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (2-1)/(5-2)
m = 1/3
The slope is m = 1/3
Use this slope, along with one of the points. I'll use the point (x,y) = (2,1). Plug these three values into the equation y = mx+b and then solve for b
y = mx+b
1 = (1/3)(2)+b
1 = 2/3+b
1-2/3 = 2/3+b-2/3
1 - 2/3 = b
b = 1 - 2/3
b = 3/3 - 2/3
b = 1/3
So the slope and y intercept are
m = 1/3
b = 1/3
Therefore the equation is [tex]y = \frac{1}{3}x+\frac{1}{3}[/tex]
Rewrite the following equation in slope-intercept form. 17x + 15y = 5 Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
y = [tex] \frac{-17}{15} x[/tex] + [tex] \frac{1}{3} [/tex]
Explanation:
The slope-intercept form of the equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
17x + 15y = 5
To put it in the slope-intercept formula, we should isolate the y as follows:
17x + 15y = 5
15y = -17x + 5
y = (-17/15) x + (5/15)
y = [tex] \frac{-17}{15} x[/tex] + [tex] \frac{1}{3} [/tex]
where:
m is the slope = -17/15
c is the y-intercept = 1/3
Hope this helps :)
Final answer:
Slope-intercept form of the equation 17x + 15y = 5 is y = (-17/15)x + 1/3, with a slope of -17/15 and a y-intercept of 1/3.
Explanation:
To rewrite the equation 17x + 15y = 5 in slope-intercept form, which is y = mx + b where m is the slope and b is the y-intercept, follow these steps:
Subtract 17x from both sides of the equation: 15y = -17x + 5.Divide both sides of the equation by 15 to solve for y: y = (-17/15)x + 5/15.Simplify the fractions to get the final form: y = (-17/15)x + 1/3.Here, the slope (m) of the line is -17/15, and the y-intercept (b) is 1/3.
The velocity of an airplane heading east is 400 knots with a wind velocity of 50 knots blowing toward the northeast. Calculate the resultant speed and direction of the plane. Round to the nearest tenth.
Answers
The velocity of the plane:
east=400 knots
The velocity of the air
50knots north east = 50/√2 north + 50/√2 east
The resultant speed would be:
total speed^2= east^2 + north^2
total speed= √(400+50/√2)^2 + (50/√2)^2
total speed= √(189534.254 + 1250)
total speed= 436.8 knots
2. To count the direction of the plane, you need to find the total speed of x(east/west) and y(north/south) axis separately then use tan formula.
east speed= 400knots + 50/√2 knots= 435.35 knots
north speed= 50/√2knots= 35.35 knots
tan a= opposite/adjacent
tan a = north speed/ east speed
tan a= 35.35/ 435.35
tan a=0.0812
a= 4.6 degrees
triangle LMN is similar to triangle XYZ with altitudes KL and WX. Find KL
Answers
Since LMN~XYZ, that means m∠N = m∠Z.
Since the angles are the same, we also know that
sin N = sin Z
Sine is the ratio of the opposite side to the hypotenuse of a right triangle. The sine of N would be the ratio of sides LK to LN, and the sine of Z would be the ratio of sides XW to XZ. That gives us:
x/28 = 3/12
Cross multiply the proportion:
12*x = 28*3
12x = 84
Divide both sides by 12:
12x/12 = 84/12
x = 7
The side length (KL) of the triangle ΔLMN will be 7. Then the correct option is B.
