Answer: The true statement is (A) P(extra large)≈0.25.
Step-by-step explanation:
Given that a piece of paper is randomly selected from a stack that contains 15 small, 44 large, and 20 extra large pieces.
We are to select the true statement.
Let S be the sample space for the experiment of choosing a piece.
Then, n(S) = 15 + 44 + 20 = 79.
Let A, B and C denote the events of choosing a small piece, a large piece and an extra large piece respectively.
So, n(A) = 15, n(B) = 44 and n(C) = 20.
Therefore, we have
Thus, the true statement is P(extra large)≈0.25.
Option (A) is correct
D. Have the same number of valence electrons
Answer: $ 2,168
Step-by-step explanation:
As we know,
Average = 
Given: The McConnell's records for January, February, March, and April show that their expenditures totaled $2,004, $1,897, $2,345, and $2,426, respectively.
Average monthly expenditure for the four months
Hence, their average monthly expenditure for the four months = $ 2,168.
