Answer:
A. The woman is relatively taller because the z score for her height is greater than the z score for the man's height.
Step-by-step explanation:
Whoever has the highest z-score, is taller relative to the population of the same gender.
The z-score of a value X in a set with mean 
and standard deviation 
is given by:
Solution:
Heights of men have a mean of 170 cm and a standard deviation of 6 cm. One of the tallest living men has a height of 236 cm. So the z-score of his height is:
Heights of women have a mean of 161 cm and a standard deviation of 5 cm.
One of the tallest living women is 224 cm tall. The z-score of the women's height is
The women has a higher z-score, so she is relatively taller.
The correct answer is A
Y/3 + 1/4 = 5/12
4y/12 + 3/12 = 5/12
4y/12 = 2/12
4y = 2
/4 /4
y = 1/2
Therefore y = 1/2
Answer:
25% is the answer because 25 x 4 = 100% and 20x4= 80
Answer:
50 gallons per hour
Step-by-step explanation:
(400 gallons) / (8 hours) = 50 gallons per hour
Answer:
The type of function the equation represents is "directly proportional" ⇒ B
Step-by-step explanation:
- The equation of the directly proportional is y = kx, where k is the constant of proportionality, k is a real number that could be positive or negative
- The equation of the inversely proportional is xy = k or y =
, where k is the constant of proportionality, k is a real number that could be positive or negative
Let us solve the question using the rules above
∵ The equation of the function is y = -8x
→ Compare it with the two forms above
∵ The equation is in the form of y = kx, where k = -8
∴ The equation represents directly proportional
∴ The type of function the equation represents is "directly proportional"
