The easiest way to solve this problem is to make a table, based on 100 total person
Prefer week ends Prefer week days Total
Female 10 55 65
Male 15 <span>20 </span>35
Total 25 75 100
The bold numbers are conclusions. The plain numbers are data.
<span>The probability that a randomly selected club member is female, given that that person prefers swimming on weekends</span> is [10 / 25] = 0.40

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
The answer is (1,5) and (4,20) they make both of the equations true
Answer:
360 whole circle minus the 60 you don't want =300
Step-by-step explanation:
Answer:
2.99x + 12.99y = 43.92
Step-by-step explanation:
socks cost 2.99 and she bought x
2.99x
blouses cost 12.99 and she bought y
12.99y
The total is
2.99x + 12.99y
The total cost was 43.92
2.99x + 12.99y = 43.92
