Answer:
C. 60,000
Step-by-step explanation:
<u>Given</u>
- 24,000 fans attended a football match
- three times as many bought tickets
- one-sixth of them cancelled their tickets
<u>Three times as many bought tickets</u>
24,000 * 3 = 72,000
<u>one-sixth of them cancelled their tickets</u>
72,000 * 1/6 = 12,000
<u>Subtract</u>
72,000 - 12,000 = 60,000
<u>Answer</u>
60,000 people are attending this week
Answer: point estimate = 3.88
Margin of error = 0.63
Step-by-step explanation:
Confidence interval is written in the form,
(Point estimate - margin of error, Point estimate + margin of error)
The sample mean, x is the point estimate for the population mean. Let m represent the margin of error. Since the confidence interval is given as (3.25 , 4.51), it means that
x - m = 3.25
x + m = 4.51
Adding both equations, it becomes
2x = 7.76
x = 7.76/2
x = 3.88
Substituting x = 3.88 into x + m = 4.51, it becomes
3.88 + m = 4.51
m = 4.51 - 3.88
m = 0.63
Answer:
70.99
Step-by-step explanation:
Use Pythagorean Theorem to find the shortest distance.
80^2-50^2=3900
Square rt= 62.44
Subtract by 15
47.44
Next find half of the circular path it is (3.14 x 15)/2
23.55
Add 47.44+23.55=70.99
Hope this is correct
