Answer:

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.

Answer:

Step-by-step explanation:

The slope of the line of best fit should be around:

(18-15)/(16-10) = 0.5

And

The y-intercept would be less than 15

Therefore, option C is the most suitable option

It costs Luis 5 to park his car at a parking meter for two hours. What is the price to park for 1 hour? Draw a bar model or writ

maksim [4K]

Answer:

The cost of parking the car for 1 hour = $2.5

Step-by-step explanation:

Cost of parking car for two hours = $5

Now, let the cost of parking the car for one hour be $x

Since, the car is parked for two hours and the cost charged is $5

So, each hour the cost of parking is same ⇒ Cost of parking one hour is half the cost of parking the car for two hours.

Since, the cost of parking the car for one hour = $x

So, cost of parking the car for two hours = 2x

But this cost is given to be $5

⇒ 2x = 5

⇒ x = 2.5

Hence, The cost of parking the car for 1 hour = $2.5

A group of friends went to the movies. They shared 2 bags of popcorn equally. If each person got 2/3 of a bag of popcorn, how ma

Gemiola [76]

Answer:

There would have been three people in the group.

Step-by-step explanation:

This is because if you add 2/3 together until you get that amount, it will add up to having three people. If this sounds confusing, here is a visual thing to help.

2/3+2/3=4/3 which can also equal 1 1/3

1 1/3 + 2/3 =2

you added 2/3 together three times to get two, so three is the answer.

Hope this helps!
