Answer:
150.88 cm²
Step-by-step explanation:
From the figure above;
- We are given the dimensions of a rectangular prism;
- we need to determine the total surface area;
From the figure you realize, there are three pairs of similar rectangles;
Thus; since area of a rectangle is L × W
Then;
First pair;
Area = 7.4 cm × 3.1 cm × 2
= 45.88 cm²
Second pair;
Area = 5 cm × 3.1 cm × 2
= 31 cm²
Third pair;
Area = 5 cm × 7.4 cm × 2
= 74 cm²
Therefore;
The total surface area = 45.88 cm² + 31 cm² + 74 cm²
= 150.88 cm²
Thus, the total surface area of the rectangular prism is 150.88 cm²

Answer: Option A & D are true statements.
Work:
For option A, it states 1 pound = 2.75. Now when we divide 16.50 by 6 we get 2.75, so option A is true.
Option B states 2.75 pounds = 1$. We already know this isn't true seeing as 2.75 pounds would equal 7.56, so option B is false.
Option C reads as 5 pounds equal 15.50. When we multiply 5 by 2.75, we get 13.75, so option C is also untrue.
Option D quotes 12 pounds equals 33. When we multiply 12 by 2.75, it equals 33, so this is a true statement!
Option E says the point 3,9 is on the graph, but its not. So this is not true.
Answer: Our required probability is 0.004672.
Step-by-step explanation:
Since we have given that
Number of adults = 7
Probability of getting adult will watch prime time TV live = 0.8
We need to find the probability that fewer than 3 of the selected adults watch prime time live.
We will use "Binomial Distribution":
here, n = 7
p = 0.8
So, P(X<3)=P(X=0)+P(X=1)+P(X=2)
So, it becomes,
So, probability that fewer than 3 of the selected adult watch prime time live is given by
Hence, our required probability is 0.004672.
Because it's a dilation of 5/3, C' would be (3 * 5/3, -6 * 5/3)
C' would be (5, -10), Option A
