Answer:
A) A cylinder with a height of 2 and a diameter of 8.
Step-by-step explanation:
The height of the cylinder is half the radius. Therefore.
Height of the cylinder = (half of the radius)/2
Answer choice A) A cylinder with a height of 2 and a diameter of 8.
Note that a diameter is found using the following formula:
d (diameter) = 2r (radius).
First, divide 2 from the diameter to find the radius:
8/2 = 4
Next, divide by 2 again to find the height of the cylinder:
4/2 = 2
In this case, the height of the cylinder is 2, ∴ the choice is correct.

Step-by-step explanation:
There are 21 socks in total. Only 7 of them are white.
When you pick your 1st sock, you have a 7/21 chance to get white.
When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.
So the probability to get a pair of white socks is 2/21.

Answer:
The z-score of a beetle with a length of 2.38 centimeters is 2.4
Step-by-step explanation:
As we know,
z = (x - µ)/σ
x is the length of the beetle species.
µ is the mean length
σ is the standard deviation
Substituting the given values in above equation, we get
z = (2.38 - 1.9)/0.2
z = 0.48/0.2
z = 2.4
