The total amount Randall spent was $20.
He bought a notebook for $8.
So he has $12 dollars left.
Then he buys 6 highlighters.
Divide 12 by 6.
Each highlighter is $2.

Find the surface area of the cylinder. Use 3.14 for pi . a hay bale with a diameter of 30 inches and a height of 72 inches about
valentina_108 [34]

Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:

we are given:

Diameter of cylinder = 30 inches

Height of cylinder = 72 inches

We need to find:

Surface area of cylinder = ?

The formula used is:

Surface\,\,Area=2\pi rh+2\pi r^2

We know radius = diameter/2

so, radius = 30/2 = 15 inches

putting values:

Surface\,\,Area=2\pi rh+2\pi r^2\\Surface\,\,Area=2*3.14*15*72+2*3.14*(15)^2\\Surface\,\,Area=6782.4+1413\\Surface\,\,Area=8195.4

So, Surface Area of cylinder = 8195.4 inches^2

mr_godi [17]

Answer:

Throw this sample out and start over again with a better sampling method

Step-by-step explanation:

Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.

Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.

Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.
