So I need help, it confuses me a lot.
There's the chart and the answers.

The answer is $0.05.

Step-by-step explanation:

Find the mean, then subtract both the means.

0.54142857142-0.49428571428=x

x=0.047143

If estimated it is 0.05.

$0.20

Step-by-step explanation:

When finding the mean, you add up all the numbers, then divide by how many numbers there are. So you add up all the costs and divide them by 7.

Week 1: 3.3

Week 2: 3.1

Then ofcouse, to find the difference you subtract 3.3 by 3.1 and you get $0.20

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
