What is the missing dimention with a cilinder with base as d and the height as 14 and it has a volume of 7433 in 3
Korolek [52]

Answer:

26in

Step-by-step explanation:

Volume of a cylinder = πr²h

Given

height h = 14in

Volume = 7433in³

Required

base d = 2r

r is the  radius

get the radius r

7433 = 3.14 * 14r²

7433 = 43.96r²

r² = 7433/43.96

r² = 169.08

r = 13.00

Since the base d = 2r

d = 2(13)

d = 26in

Hence the base of the cylinder is 26in

The final exam of a particular class makes up 40% of the final grade, and Moe is failing the class with an average (arithmetic m
amm1812

Answer:

%82.5

Step-by-step explanation:

  1. The final exam of a particular class makes up 40% of the final grade
  2. Moe is failing the class with an average (arithmetic mean) of 45% just before taking the final exam.

From point 1 we know that Moe´s grade just before taking the final exam represents 60% of the final grade. Then, using the information in the point 2 we can compute Moe´s final grade as follows:

FG=0.40*FE+0.60*0.45,

where FG is Moe´s Final Grade and FE is Moe´s final exam grade. Then,

\frac{ FG-0.60*0.45}{0.40}=FE.

So, in order to receive the passing grade average of 60% for the class Moe needs to obtain in his exam:

FE=\frac{ 0.60-0.60*0.45}{0.40}=0.825

That is, he need al least %82.5 to obtain a passing grade.

The time it takes to process phone orders in a small florist/gift shop is normally distributed with a mean of 6 minutes and a st
Aleksandr [31]
E) 12 minutes

A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes

Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.
