Let x be the population distribution.
p(25 ≤ x ≤ 33) = p((25 - 29)/4 ≤ z ≤ (33 - 29)/4) = p(-1 ≤ z ≤ 1) = p(z ≤ 1) - p(z ≤ -1) = p(z ≤ 1) - [1 - p(z ≤ 1)] = 2p(z ≤ 1) - 1 = 2(0.84134) - 1 = 0.68268 = 68%
p(21 ≤ x ≤ 25) = p((21 - 29)/4 ≤ z ≤ (25 - 29)/4) = p(-2 ≤ z ≤ -1) = p(z ≤ -1) - p(z ≤ -2) = [1 - p(z ≤ 1)] - [1 - p(z ≤ 2)] = p(z ≤ 2) - p(z ≤ 1) = 0.97725 - 0.84134 = 0.13591 = 13.5%
16 % of tiles are black
<em><u>Solution:</u></em>
Given that floor tiles come in red, blue, and black
To find: percent of the tiles that are black
From given question,
number of red tiles = 16
number of blue tiles = 5
number of black tiles = 4
Therefore, total number of tiles = number of red tiles + number of blue tiles + number of black tiles
Thus total number of tiles = 25
<em><u>To percent of the tiles that are black, use the following formula:</u></em>
Thus 16 % of tiles are black

Answer:
F(x) = 3
Step-by-step explanation:
Just substitute x with 1 and you add it with 2 and your answer is three
Answer:
0.16km
Step-by-step explanation:
Unless I am missing something it is a simple subtraction problem and the time is not needed. It is simply asking how much farther Avery ran than Max, which is 1.61km - 1.45km which is 0.16km
