Matt said that the function is linear.
Justine said that the function is nonlinear.
Which of the following explains who is correct?
Matt, because for every 1-unit increase in x, there is an increase in y by 2
Matt, because for every 2-unit increase in x, there is an increase in y by 1
Justine, because the point (−3, −8) does not lie on the straight line that contains the other points
Justine, because the point (0, 0) does not lie on the straight line that contains the other points
Justine, because the point (0, 0) does not lie on the straight line that contains the other points.
Explanation:
See the graph below. The following coordinates are not in a stright line.
Hence, it is a non linear function. Justine is right.
When drawn a straight line. the coordinates: (0,0) does not lie on the line.
Find the area of the triangle.
Answer:
20 m²
Step-by-step explanation:
Formula (Area of triangle):
[tex]\text{A (Triangle)} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.
[tex]\implies \text{A (Triangle)} = \dfrac{1}{2} \times (7 + 3) \times (4)[/tex]
Simplify the right-hand-side as needed to evaluate the area.
[tex]\implies \text{A (Triangle)} = \dfrac{1}{2} \times (10) \times (4)[/tex]
[tex]\implies \text{A (Triangle)} = \dfrac{40}{2} = 20 \ \text{m}^{2}[/tex]
Therefore, the area of the provided triangle is 20 m².

A new tire company produces a different type of tread and tests 100 randomly selected tires. This sample of 100 tires lasted an average of 52,000 miles. Assuming the new type of tread does not improve the mileage of the tire, 200 sample means were simulated and displayed on the dotplot.
Using the dotplot and the sample mean mileage, is there convincing evidence that the new type of tread improves the mileage?
Yes, because a mean mileage of 52,000 or more occurred only 7 out of 200 times, the mean mileage is statistically significant. There is convincing evidence the new type of tire tread improves mileage of the tire.
Yes, because a mean mileage of 52,000 or less occurred 193 out of 200 times, the mean mileage is statistically significant. There is convincing evidence the new type of tire tread improves mileage of the tire.
No, because a mean mileage of 52,000 or less occurred 193 out of 200 times, the mean mileage is not statistically significant. There is not convincing evidence the new type of tire tread improves mileage of the tire.
No, because a mean mileage of 52,000 or more occurred 7 out of 200 times, the mean mileage is not statistically significant. There is not convincing evidence the new type of tire tread improves mileage of the tire.
The convincing evidence is Yes, because a mean mileage of 52,000 or more occurred only 7 out of 200 times, the mean mileage is statistically significant.
What is a dot plot?A dot plot is known to have the same characteristics as a bar graph as both are made up of different height of “bar” that consist of dots which is said to be equal to the number of items in any of the stages or categories.
Conclusively, when a person uses a dot plot and the sample mean mileage, one will be able to find a convincing evidence that the new type of tread improves the mileage because out of mean mileage of 52,000 or more, only 7 out of 200 times, took place and this shows that the mean mileage is statistically significant and that the new type of tire tread boast the mileage of the tire.

Consider the following graph, which details one bookstore’s sales over the course of one day, divided by genre.
A graph titled Book Sales by Genre has genre on the x-axis and Number sold on the y-axis. Romance, 52; horror, 55; Fantasy, 60; Biograph, 57; Humor, 58; Cookbook, 54.
By percent, how much greater do sales of horror books appear to be than sales of cookbooks? How much greater are they in reality?
The percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given that:
Genre number sold
Romance 52Horror 55Fantasy 60Biography 57Humor 58Cookbook 54Let we have:
Number of horror books sold = P% greater than number of cookbooks sold
55 = P% greater than 54
55 = 54 + P% of 54
1 = P% of 54
[tex]1 = \dfrac{P}{100} \times 54\\\\P = \dfrac{100}{54} \approx 1.85[/tex]
Thus, the percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

What does she pay in total premiums?
O$1239.00
O$1379.80
O $1551.60
O $1610.70
Answer: $1239.00
Step-by-step explanation:
I had to recheck on this.
For females that are ages 25-29, they have base auto insurance rate, meaning that the rate is set at 1. So multiply the base premium and base rate, 1239x1, and obviously it's the same 1239.

The figure below illustrates the market for steel. If the steel market is competitive, firms can produce steel at a constant marginal cost of $100 per ton. Therefore, the price of steel is $100 per ton, and 100 tons are produced. Assume that if all the steel companies consolidate into a monopoly, the monopoly’s marginal cost will fall to $70 per ton. Use the straight line tool to draw the monopoly’s marginal revenue and marginal cost lines (extend the marginal cost line to 300 tons). Then use the plot point tool to plot the monopoly’s profit-maximizing price and output on the demand curve.
If the market is controlled by a monopoly, total surplus is $____
The monopoly price will be given as 110 dollars per unit. Then the total surplus will be 4800 dollars.
How do determine the monopoly price and the total surplus?The figure below illustrates the market for steel.
If the steel market is competitive, firms can produce steel at a constant marginal cost of $100 per ton.
Therefore, the price of steel is $100 per ton, and 100 tons are produced.
Assume that if all the steel companies consolidate into a monopoly, the monopoly’s marginal cost will fall to $70 per ton.
If the market is controlled by a monopoly, the total surplus will be
The demand curve has to be defined the demand curve will be
P = 150 - 0.5Q
Total revenue, TR = 150Q - 0.5Q^2
MR = 150 - Q
MC = $ 70
The monopolist will maximize profit at MR = MC
150 - Q = 70
=> Q = 80 units
Monopoly price, P = 150 - 0.5 × 80 = $ 110 / unit
Total surplus = (1/2)×(150-110)×80+(110-70)×80
= 1,600 + 3,200

if your expenses total $5,600 per month. you charge$25 per hour and have contracts for study work that total 45 hours per week for 52 weeks of the year. How does this rate cover your expenses?
Answer:
$8700
Step-by-step explanation:
since there are 12 months in a year:
5600 x 12 = $67200
pay per week: 25 x 45 = $1125
pay per year: 1125 x 52 = $58500
67200 - 58500 = $8700 left over

Find the EXACT value of sec (θ)
Show steps
By applying fundamental and derivate trigonometric expressions it is to be concluded that the secant of the line segment whose terminal side is (3, - 2) is approximately 1.202.
How to apply trigonometric expressions
Trigonometric expressions are trascendent expressions derived from relationships between sides of the triangle contained in a goniometrical diagram.
There are at least six trigonometric expressions: sine, cosine, tangent, cotangent, secant, cosecant. The first two expressions are fundamental, whereas the rest are derived from them.
We can derive an expression for the secant of the angle by applying trigonometric expressions:
[tex]\sec \theta = \frac{1}{\cos \theta} = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex] (1)
If we know that x = 3 and y = - 2, then the secant of the angle is:
[tex]\sec \theta = \frac{\sqrt{3^{2}+(-2)^{2}}}{3}[/tex]
sec θ ≈ 1.202

Subtract 89.768 from 201.316
show your work
Answer:
111.548
-------------------------------
Subtract 201 from 89.
[tex]201 - 89 = 112[/tex]
we can estimate the answer will be close to 112
Next, work with the decimals. Note that the more you subtract, the bigger the decimal places get.
[tex]0.768 - 0.316 = 0.452[/tex]
Round 0.452 up from the hundredths place to nearest tenths place.
[tex]0.452 = 0.5[/tex]
Since the decimal place is bigger, estimate 0.55 instead.
Subtract 0.22
[tex]0.55 - 0.2 = 0.548[/tex]
Add this number to 112
[tex]112 + 0.548 = 112.548[/tex]
Subtract 1 because of the estimate.
[tex]112 - 1 = 111[/tex]
Therefore, we have 111.548 based off of subtracting and estimating in a specific method.
