Answer:
The percentage of men meeting the height requierements is 11.47%.
As women have a less mean height, closer to the height requierments than men's mean height, it is expected that more percentage of women will fall within the height requirements.
Step-by-step explanation:
We have men's height normally distributed with mean 67.4 in and standard deviation 3.7 in.
The amusement park requires heights between 57 in and 63 in.
We can calculate the proportion using the z-scores and the standard normal probability distribution.
The percentage of men meeting the height requierements is 11.47%.
Answer: C - 15.81
Step-by-step explanation:
pythagorean theorum: a^2 + b^2 = c^2
13^2 + 9^2 = c^2
169 + 81 = c^2
c^2 = 250
root both sides
c = 15.81
Answer:
10.8 kilograms
Step-by-step explanation:
Ok, so the first thing we need to do is subtract 50% of 49.98. We know 50% of 49.98 is 24.99, so lets subtract. 49.98 - 24.99 = 24.99. Then we need to take another $10 off the price. That leaves the final price to be $14.99
Answer:
Is shaded 5/8 of the area of the rectangle
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of triangle ABC represent 1/4 of the total area
The area of triangle CDE represent 1/8 of the total area
The shaded region is composed by one triangle equal to triangle ABC and three triangles equal to triangle CDE
so
The area of the shaded region is equal to
therefore
Is shaded 5/8 of the area of the rectangle
