We can find the standard deviation of D by adding the variances of the heights and taking the square root:

Representing probability with area
When D= M-W =0, their heights are equal. When the man is taller, D is positive, and when the woman is taller, D is negative. Since we know the distribution of the difference D is normally distributed, the probability that the woman is taller than the man can be found by calculating the shaded area below D=0, in the corresponding normal distribution:
A standard normal curve is plotted on a horizontal axis representing D, that goes from negative 17 to 37. The mean, or mu sub D, = 10. The standard deviations, or sigma sub D = 9. The value 0 is marked. The area under the curve to the left of 0 is shaded, representing the probability that the woman is taller. The area to the right represents the probability that the man is taller.

Step-by-step explanation:
1 day = $ 26.95
3 days = 26.95 × 3
= $80.85
Remainder = $100 - $80.85
= $19.15
1 mile = $ 0.27
= $19.15 ÷ $0.27
= 71 miles

Answer:
P=75.922 ≈ 76
∘Step-by-step explanation:
What function uses the ADJACENT and the HYPOTENUSE?
SOH-CAH-TOA
cos P = adjacent/hypotenuse= 1.8/7.4
Pcos^-1 = (1.8/ 7.4)
P=75.922 ≈ 76
