The scatterplot below shows the relationship between the number of gallons of gasoline in the tanks of 14 cars, and the maximum number of miles the cars can be driven on the given amount of gasoline.

Gasoline
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).

Based on the data collected, which combination of gallons in the gas tank and maximum number of miles seems most likely to be possible?

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.

The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. The adult tickets sold for $7.50 each and the student tickets sold for $4.50 each. If the junior class collected $2,212.50 in ticket sales, how many student tickets did the class sell
**No answer choices, please explain how you got the answer cause I have no clue how to do this**
❤❤

Answers

Answer: I believe this is correct, i got 80 tickets

Step-by-step explanation:

I divided 2212.50 by the adult tickets, 7.50, and got 295. if the adults sold 295 tickets, then the students would have sold 80, because thats all that were left. I hope I helped

The number of student tickets the class sold is 200.

Let

x = number of student ticket sold

y = number of adult ticket sold

The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. Therefore,

Total tickets:x + y = 375

The junior class collected $2,212.50 in ticket sales. Therefore,

Total sold:4.50x + 7.50y = 2212.50

Combine the equation to get the number of student ticket sales.

x + y = 375

4.50x + 7.50y = 2212.50

Multiply equation(i) by 4.50x

4.50x + 4.50y = 1687.5

4.50x + 7.50y = 2212.50

3y = 525

y = 525 / 3

y = 175

x + y = 375

x = 375 - 175

x = 200

Answer:

72%

Step-by-step explanation:

18/25 = 0.72

0.72 x 100 = 72

Answer:

72%

Step-by-step explanation:

Step 1 we make the assumption that 25 is 100% since it is our output value

Step 2 we next represent the value we seek with x

Step 3 from step 1, follows that 100%=25

Step 4 in the same vein, x%=18

Step 5 this gives us a pair of simple equations: 100% = 25(1)

X%= 18(2)

Step 7: taking inverse of both sides yields

X%\100% = 18/25

—> = 72%

Therefore, 18 is 72% of 25

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0
