Now Steve, you can tap these into your calculator one by one,
get all the quotients, and mark the ones that are 4.2, all in about
3 minutes.
There are three (3) of them in the list.
One of them is 'C'. 27.3 ÷ 6.5 = 4.2
Now pick up your calculator and find the other two. You can do it !
Answer: option A
Step-by-step explanation:
The volume of a cylinder can be calculated with the formula:
Where r is the radius and h is the height of the cylinder.
The radius is diameter divided by 2, then:
Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:
Answer:
A= 13 B=13.1
Step-by-step explanation:
A-B= -0.1
B-A= 0.1
<span>The number of ways to permute three correct answers among five questions is 5Choose3 which is 5!/(3!*2!) which equals 10.
We must then have the correct answer three times which happens .25 of the time, and two wrong answers 75 of the time.
So the probability is 10*0.25^3*.75^2 which is 0.087890625 or roughly an 8.8% chance.</span>
