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:
D. 9
Step-by-step explanation:
When you add 1 + 4 + 5 + 5 + 5 + 6 + 9 + 10 + 10 + 11 + 12 + 12 + 15 + 15 + 15 = 135. Which is all of the numbers given to you, and since mean is when you add all of the numbers together, and than divide it by the amount of numbers there, you will take that 135 and divide it by 15. 135 / 15 = 9. Which gets you to finally getting an answer of 9. so D. 9 is correct.
Answer:
0, -11
Step-by-step explanation:
y-4=-3(x-(-5))
y-4=-3x-15
y=-3x-15+4
y=-3x-11 the ordered to the origin is -11
the y-intercept is at the point (0, -11)
