Answer:
52 weeks
Step-by-step explanation:
The club starting with $270 (club 1) is increasing their bank balance each week by ...
... $280 -270 = $10
The club starting with $10 (club 2) is increasing their bank balance each week by ...
... $25 -10 = $15
Club 2 is gaining on Club 1 by $15 -10 = $5 each week. So, the initial difference of $270 -10 = $260 will be overcome in ...
... $260/($5/week) = 52 weeks
_____
The same result is shown in the attached graph, which also shows that both clubs' bank balances will be $790 at that time.
Answer:
Step-by-step explanation:
the sum of the interior angles of a hexagon is 720 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the interior angles, we know that the sum of all the angles is 720 degrees.
Now,
102+146+158+120+124+x=720
or,650+x=720
or,x=70
Therefore The value of X is 70 degree.
Answer: 4 lbs is greater than 60 ounces
Step-by-step explanation:
4 lbs equals 64 ounces because 4x16=64.
Answer:
4 lb > 60 ounce
Step-by-step explanation:
We are comparing pounds to ounces so we need to convert pounds to ounces. We know that a pound is 16 ounces.
4 lbs * 16 ounces / lb = 64 ounces
4 lb > 60 ounce since 64 ounces > 60 ounces

Answer:
Option E, two-proportion z test should be used to determine whether these data provide sufficient evidence to reject the hypothesis that the proportion of shoppers at the suburban mall who had been to a movie in the past month is the same as the proportion of shoppers in the large downtown shopping area who had been to a movie in the past month
Step-by-step explanation:
The complete question is
In a random sample of 60 shoppers chosen from the shoppers at a large suburban mall, 36 indicated that they had been to a movie in the past
month. In an independent random sample of 50 shoppers chosen from the shoppers in a large downtown shopping area, 31 indicated that
they had been to a movie in the past month. What significance test should be used to determine whether these data provide sufficient
evidence to reject the hypothesis that the proportion of shoppers at the suburban mall who had been to a movie in the past month is the same
as the proportion of shoppers in a large downtown shopping area who had been to a movie in the past month?
A one-proportion z interval B two-proportion z interval
B two-proportion z interval
C two-sample t test D one-proportion z test
D one-proportion z test
E two-proportion z test
Solution
Two proportion z test is used to compare two proportions. In this test the null hypothesis is that the two proportions are equal and the alternate hypothesis is that the proportions are not the same. The random sample of populations serve as two proportions.
Hence, option E is the best choice of answer

Step-by-step explanation:
(b) What is the probability that a participant chosen at random was not satisfied with their service?
Answer:
(a) The probability is 31.44%
(b) The probability is 9.345%
Step-by-step explanation:
The probability for part (a) is calculated as a multiplication of:
65.5% * 48% = 31.44%
Where 65.5% is the percentage of participants that had not switched service in the past 3 years and 48% are the percentage of those 65.5% that were very satisfy. So, the 31.44% of the participants had not switched service in the past 3 years and were very satisfied with their service.
Then, for part b, we have 2 cases:
So, the probability is calculated as a sum of these two probabilities.
Therefore, the probability for case 1 is calculated as:
34.5% * 10% = 3.45%
Where 34.5% is the percentage of participants that had switched service in the past 3 years and 10% are the percentage of those 34.5% that were not satisfy.
At the same way, the probability for case 2 is:
65.5% * 9% = 5.895%
Finally, the probability that a participant chosen at random was not satisfied with their service is the sum of 3.45% and 5.895%. That is:
3.45% + 5.895% = 9.345%
