Answers

Answer:

1. The graph is non-proportional because it starts from (0, 2).

2. The slope of the line is 3.

3. y=3x+2

Step-by-step explanation:

The graph is non-proportional since it didn't start from the origin (0, 0). If the graph starts from the origin, then it's proportional.

To find the slope of the line, use this equation, [tex]m=\frac{y2-x2}{y1-x1}[/tex] or [tex]\frac{rise}{run}[/tex] to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.

[tex]m=\frac{5-2}{1-0} =\frac{3}{1} =3[/tex]            I chose (0, 2) and (1, 5) to find the slope

Once you find the slope, write the equation in y=mx+b form to find what b is with one of the points given.

[tex]2=3(0)+b[/tex]

[tex]-0[/tex]   [tex]-0[/tex]

----------------------

2 = b

The box-and-whisker plots below show the numbers of motor vehicles produced in four different regions for selected years since 1950.

Which region has had the GREATEST amount of variability in annual vehicle production?

A. Japan

B. Europe

C. Canada

D. United States

Answers

Answer: A. Japan

Step-by-step explanation:

Japan would have more variables in the production the vehicles annual leave because it has the longest box out of all other reasons, and when you’re dealing with box equations the longest box has the most variables when the short box has the least variables.

Japan region has had the greatest amount of variability in annual vehicle production.

What is the box-and-whisker plot?

A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.

More varied data is implied by larger boxes.

When comparing box plots, especially when the medians are comparable, that is something to keep an eye out for.

Whisker lengths and box sizes with wider ranges signify more varied data.

So, from the given choices,

Japan shows the greatest amount of variability.

Therefore, the Japan box plot is the required plot.

A car that normally sells for 25,900 is on sale for 84.5% of the actual price. What is the sale of the car?

Answers

Answer:

$21,885.5

Step-by-step explanation:

84.5% of 25,900 =

0.845 * 25,900 =

21,885.5

Because it says that the car is on sale for 84.5% of it's original price means that that is the price of the car.

If it had said that the car was 84.5% off, we would have had to subtracted 21,885.5 from 25,900, however, it didn't so it's ok.

Hope that this helps, have a good day/night and good luck!

Answers

Answer:

f(x) = -(x-3)^2 + 4

Step-by-step explanation:

(h; k) are the coordinates of the vertex.

On the graph are (3, 4), therefore we have:

f(x) = a(x-3)^2 + 4

We have the x- intercept (1,0) -> x=1; y=0.

Substitute them into the equation:

0 = a(1 - 3)^2 + 4

0 = a(-2)^2 + 4

4a + 4 = 0 | -4

4a = -4   |-4

a = -1

So, we have the answer:

f(x) = -(x-3)^2 + 4

f(x) -(x-3)^2 + 4

19 wouldn’t be reasonable, but it’s a trick question, because it really depends on the weight of the items, but if we don’t know what items they are, then we have to predict that the biggest number would be to much, so I think it’s B, or 19.
