Casey said that 40 people were surveyed. Is his answer reasonable?

Answers

If 40 people were surveyed then it is reasonable
It depends on your population size, and if your sample is biased. If your sample was 40 out of 100, then yes, it would be reasonable. But if your sample was 40 out of 1000, then no because the sample is too small.

In an election 32 thousand people voted for Mayor Jackson. A total of 56 thousand people voted in the election. What is the ratio of the number of votes that were not for mayor Jackson to the total number of votes in simplest form?

Answers

Answer:

Ratio of the number of votes that were not for mayor Jackson to the total number of votes is 3:7

Step-by-step explanation:

Votes of Mayor Jackson = 32,000

Total Votes = 56,000

Votes not for Mayor Jackson = 56000 - 32000

Votes not for Mayor Jackson = 24000

ratio of the number of votes that were not for mayor Jackson to the total number of votes = Votes not for Mayor Jackson:Total Votes

= 24,000:56,000

=24:56 (divide numerator and denominator by 8)

=3:7

So, ratio of the number of votes that were not for mayor Jackson to the total number of votes is 3:7

Answer:

3 : 7

Step-by-step explanation:

It is given that,

In an election 32,000 people voted for Mayor Jackson

A total of 56,000 people voted in the election.

To find the ratio

Total number of people voted = 56000

Number of people voted for Mayor Jackson = 32000

Number of  votes that were not for mayor Jackson = 56000 - 32000 = 24000

The ratio of the number of votes that were not for mayor Jackson to the total number of votes = 24000 : 56000

 = 3 : 7

Chad buys peanuts in 2-pound bags. He repackages them into bags that hold 5/6 pound of peanuts. How many 2-pound bags of peanuts should Chad buy so that he can fill the 5/6-pound bags without having any peanuts left over

Answers

You need to get a whole so
5/6+5/6=10/6 not a whole
10/6+5/6 =15/6= not a whole
15/6 +5/6= 20/6 not a whole
20/6+5/6=25/6 not a whole
25/6+5/6=30/6
There are 5 wholes in 30/6 so 5 bags
