the answer is A ........._________---------
Answer: The answer is 10 inches.
Step-by-step explanation: Given that the area of a trapezoid is 50 square inches and the bases are 3 inches and 7 inches. We are to find the height of the trapezoid.
We know that the area of a trapezoid with height 'h' and bases 'a' inches and 'b' inches is given by

In the given question,
a = 3 inches, b = 7 inches, A = 50 square inches, h = ?
Therefore,

Thus, the required height is 10 inches.
Answer: a. 0.04
Step-by-step explanation:
Given : Number of multiple choice questions = 2
Choices given in each question = 5
Since only one choice is correct out of 5.
So, the probability of selecting the correct answer = 
Also, both questions are independent of each other.
It means , The probability of answering the two multiple choice questions correctly if random guesses are made
=( Probability of selecting the correct answer in question 1 ) x ( Probability of selecting the correct answer in question 2 )
= 
Hence, the required probability =0.04
