Surface area of a prism=2(long x wide)+2(long x high )+2(wide x high)
Data:
long=5 m
wide=2 m
high=2 m
Surface area of this prism=2(5 m * 2 m)+2(5 m*2 m)+2(2 m*2m)
=2(10 m ²)+2(10 m²)+2(4 m²)
=20 m²+20 m²+8 m²
=48 m²
Answer: C 48 m²
Joey has 21 socks all in all. Out of them, there are 10 dress socks and 13 brown socks. There are 7 brown dress socks. The probability,
P (brown or dress) = P (brown) + P (dress) - P (brown and dress)
Substituting,
P(brown or dress) = 13/21 + 10/21 - 7/21 = 16/21
Thus, the answer is 16/21.

Step-by-step explanation:
It's a variable that deals with various labels, rather than the usual type of numeric variable you may be used to.
One example of a categorical variable is color. You could have red, green, blue, yellow, and orange as the five choices for your categorical variable. Each color is a label or category.
This is an example of a qualitative variable. We don't have any numeric data attached to color. They're simply names or labels. In contrast, a quantitative variable is something like a person's height since a number is attached here (more specifically its a continuous quantitative variable).
