The cost of one adult ticket is $12 and cost of one child ticket is $8.
Step-by-step explanation:
Let,
Cost of one adult ticket = x
Cost of one child ticket = y
According to given statement;
x+4y=44 Eqn 1
5x+2y=76 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 18
Putting y=8 in Eqn 1
The cost of one adult ticket is $12 and cost of one child ticket is $8.

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.
