A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.

b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.

c) f(x) = 2.69 + 0.48(x-1)

d) domain is the x values; range is the y values

The table displays The scores of students on the recent exam. Find the mean of the scores to the nearest 10th.
Dafna1 [17]

Answer:

80

Step-by-step explanation:

To find the mean we add up all the numbers and then divide that number by the amount of numbers we added up.

So in this case we added up 65, 70, 75, 80, 85, 90 & 95. This gives us 560. Now we divide 560 by 7 as that is the amount of numbers we added up. This gives us 80 which means the answer is 80.

I hope this helped! :)

A cylindrical can has a volume of, 1250 cubic centimetres. What is the height of the can if its radius is 8 centimetres? Round y
PIT_PIT [208]

A cylinder is a three-dimensional structure formed by two parallel circular bases connected. The height of the can that has a volume of 1250 cm³ if the radius is 8 cm is 6.217 cm.

<h3>What is a cylinder?</h3>

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.

Given the volume of the cylinder is 1250 cm³, and the radius of the cylinder is 8 cm. Therefore, the volume of the cylinder can be written as,

\text{Volume of the cylinder} = \pi r^2h

1250 = \pi \times (8)^2 \times h\\\\h = 6.217\rm\ cm

Hence, the height of the can that has a volume of 1250 cm³ if the radius is 8 cm is 6.217 cm.
