Step-by-step explanation:
172-162 = 10
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.

Answer:
A) 75 C) 20
Step-by-step explanation:
A) multiply the 25 questions by 3 to get the highest score possible since you would get them all correct. 25 x 3 = 75
C) Multiply 3 by 10: 3 x 10 = 30 He missed 5 so multipy 5 and 2: 5 x 2 =10 30 - 10 = 20
The answer is b because of the thing right there’s
