Answer:
115416 is you answer!!!!!!!!!!!!!!!!!
Step-by-step explanation:
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%
You would have to add 9+4+12 to get your answer
The answer would either be (-3,5), (5,-3), (9,-7), or (-7,9). I forget where the <em>x </em>and <em>y</em> go, but those are your answer choices.
72/9 is equivalent to 8/1
so, option A is your answer.
