Answer: 554
Step-by-step explanation:
Formula we use to find the sample size :
Given : Standard deviation : 
Margin of error : E=one quarter hour = 0.25 hour
Two-tailed , Critical value use for 0.95 degree of confidence:
i.e. 
Hence, the required sample size = 554
i.e. 554 executives should be surveyed.
This the problem we are looking at: 6 pounds/18 = 72 ounces /?
To solve this, we have to make the unit of measurement the same. There are 16 ounces in 1 pound. So, there are 72 ounces in 4.5. To find that you just do 72 divided by 16. This is the new problem we are looking at: 6 pounds/18 = 4.5 pounds/?
To find ?, you must divided 6 divided by 4.5 to find the difference between the two to keep the same rate. That equals 1.33333333.
What is done to the numerator, you must do to the denominator to keep the same rate so now you divide 18 divided by 1.33333333 which equals 13.5
So for 72 ounces (4.5 pounds) it will cost $13.50
I hope this helps:)
No OK let's see how long Is the debate, the second debate started 20 late then it started at 5:10 so to know the length of the debate we should subtract the 2 shows so 5:10-3:15 = 1:55 minutes we also should subtract 30 m because of the break so 1:55-30 = 1:25 minutes so the show length is 1:25 minutes so to know when the 2nd show will end we should add 5:10+1:25 = 6:35 p.m
Answer:I believe the range is changed the most as it goes from 14 - 2 = 12 to 14 - 10 = 4.
There is a very large gap between 12 and 4 for this data set. I hope this helps!!
Step-by-step explanation:
I don't know if this is right but i think the answer is 11 because as the number of people in the group goes up the price keeps decreasing by 3 so I made a table to see the difference...
1=42
8=39
9=36
10=33
11=30
