Answer:
2.5
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%
50°
angle CXF and DXF are complementary which means they add to 90°
to 40° + x = 90
x = 50
The answer is <span>0.145</span>
<span>
14 1/2 can be expressed as:
</span>

<span>
Since we know that x% is x/100, then </span>
14 1/2 % can be expressed as:
14 1/2% = 14.5% = 14.5/100 = 0.145
