Answer:

25

Step-by-step explanation:

To calculate rate, divide the number of cans by the time to get "Cans per minute".

300/15min = 20/min

Let m represent minutes and c for cans.

We write an equation for the problem:

c = 20m

We want to know the time for 500 cans, so substitute 500 for c.

500 = 20m

Isolate m and solve:

m = 500/20

m = 25

It will take 25 minutes to put 500 labels.

If the data point is at (3, 10.5) and the prediction equation is y = -6.1x + 12.5, what is the value of the residual for this da
Keith_Richards [23]

Given:

The data point is (3,10.5).

The prediction equation is y=-6.1x+12.5.

To find:

The value of the residual for this data point.

Step-by-step explanation:

The data point is (3,10.5). So, the actual value is 10.5 at x=3.

Prediction equation is

y=-6.1x+12.5

Putting x=3, we get

y=-6.1(3)+12.5

y=-18.3+12.5

y=-5.8

The formula for residual is:

Residual = Actual value - Expected value

Residual=10.5-(-5.8)

Residual=10.5+5.8

Residual=16.3

Therefore, the residual for the given data point is 16.3.

My mom walks 1 mile in 14<br> minutes. If she walked for 56<br> minutes, how far did she walk?
marysya [2.9K]

Answer:

4 miles

Step-by-step explanation

If your mom can walk 1 mile in 14 minutes then 2 miles would take her 28 minutes 3 miles would take her 42 minutes and finally if she walked 4 miles it would take her 56 minutes.

14 + 14 + 14 + 14 = 56

14 x 4 = 56
