A graph has gallons in gas tank on the x-axis and maximum miles on the y-axis. A line goes through points (9, 280) and (12, 360).

B.9 gallons in the gas tank and 280 miles.

From the given figure we see that the line of best fit passes through the point (13,400) and (17,520)

We know that the equation of a line passing through two point (a,b) and (c,d) is calculated by using the formula

y - b = d-b/c-a x (x-a)

Here we have:

(a,b)=(13,400) and (c,d)=(17,520)

Hence, the equation of line of best fit is: y - 400 = 520 - 400/17-3 x (x - 13)

y-400=120/4 x (x-13)

y=400=30x(x-13)

y-400=30x-390

y=30x-390+400

If u want to check your answers

0 gallons in the gas tank and 20 miles

when x=0 we have:

y=10≠20

Hence, option: A is incorrect.

9 gallons in the gas tank and 280 miles .

when x=9 we have:

y=30×9+10

y=280

Hence, option: B is correct.

11 gallons in the gas tank and 360 miles

when x=11; we have:

y=30×11+10

y=340≠360

Hence, option: C is incorrect.

19 gallons in the gas tank and 520 miles

when x=19; we have:

y=30×19+10

y=580≠520

Hence, option: D is incorrect.

During a sports competition, students participated in races of various distances. The data is shown in the frequency table. What is the range of lengths of the various races?

Answers

Answer:

150

Step-by-step explanation:

I believe the lengths are on the left and to find a range you subtract the largest and smallest numbers. In this case the largest number is 200 and the smallest is 50.

And 200-50=150

Hence, the range is 150.

what is range?

The range is the difference between the largest and smallest numbers. The midrange is the average of the largest and smallest number.

How to solve?

We know that,

highest distance(meters) = 200

lowest distance(meters) = 50

Hence, Range = 200-50 = 150

For each diagram, decide if y is an increase or a decrease of x. Then determine the percentage.

Answers

Answer:
In A: y is a 25% decrease of x
In B: y is a 25% increase of x
Step-by-sep explanation:
For A:
The diagram in A shows that x = 4, while y = 3.
Thus, this means that y decreased by 1, relative to x.
The percentage decease would be:

Therefore, y is a 25% decrease of x.
For B:
The diagram for B shows that x = 4, while y = 5.
Thus, this means that y increased by 1, relative to x.
The percentage increase would be:

Therefore, y is a 25% increase of x.
