Mean__
Median__
Mode__
Range__

mean=5,median=4,mode=4,range=6

Step-by-step explanation:

arrange these numbers in order

2,4,4,7,8

to find mean, you have to add up all of the numbers and divide by the amount of numbers there are.

all of them added together is 25. because there are five numbers, 25divided by 5 is well... 5

median is picking the number smackdab in the middle in this case, it would be 4, because 4 is right there.

mode means most common. because four is the only one that appears twice, 4 would be the mode

Range is the difference between the lowest number an the highest number. In this case, 2 and 8. 8-2=6 so range is 6

the answer is a.

135 and 80

step-by-step explanation:

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
