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

Answer:
g = 4+2m
Step-by-step explanation:
Grandma is 4 years older than twice mothers age
is means equals
g = 4+2m where g is grandmothers age and m is mothers age
It is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)<span>(1/4) = 0
</span>factor 1/4
(4v - 14)(4v - 2)(1/2)<span>(1/2)</span> = 0
and divide each:
(2v - 7)(2v - 1) = 0
