Two studies were completed in Georgia. One study in northern Georgia involved 3,000 patients; 84% of them experienced flulike sy

mptoms during the month of December. The other study, in southern Georgia, involved 2,000 patients; 75% of them experienced flulike symptoms during the same month. Which study has the smallest margin of error for a 99% confidence interval?
The northern Georgia study with a margin of error of 2.5%.
The southern Georgia study with a margin of error of 2.5%.
The northern Georgia study with a margin of error of 1.7%.
The southern Georgia study with a margin of error of 1.7%.

Answer:

The northern Georgia study with a margin of error of 1.7%.

All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)

Step-by-step explanation:

The best and most correct answer among the choices provided by the question is the third choice "The northern Georgia study with a margin of error of 1.7%."

All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)

I do not understand this question? Using partial quotients, which would be the best choice for the first number to subtract in t
marysya [2.9K]

Answer:

B. 520

Step-by-step explanation:

Partial quotient is simply the method used to find the value of a quotient by dividing bits by bits until you get to the answer. For instance if you want to divide 124/4

Whatever closest multiple of 4 to 124 you remember, write it down. For instance I remember 80 first.

80 is the 20th multiple of 4 (80÷4 = 20).

Then subtract the number from the original number you want to divide

124 – 80 = 44

Again, write down the closest multiple of 44 you remember. To me is 40, and it is the 10th multiple.

Subtract 40 from 44 you have 4 left.

It's now easy to divide 4 by 4 which is 1.

To now get the quotient in total, you'll add up

20 + 10 + 1 = 31.

Therefore, to use partial quotient in this problem, the best choice to begin with will be 520 because it is the 20th multiple of 26. Although 780 is the 30th multiple of 26, 520 will be easier to remember. For this reason, it is the best choice.

Identify the pattern.Write the next 3 terms in each sequence. 83,75,67,59...
ExtremeBDS [4]
The pattern is the subtract 8 from the previous number.

So the next number: 59 - 8 = 51

And the next: 51 - 8 = 43

And the next: 43 - 8 = 35

PLS HELP WITH 29 30 AND 31 WILL GET BRAINLIEST
grigory [225]

<u>Answer:</u>

29. 132 miles

30. 134 miles

31. 154 miles

<u>Step-by-step explanation:</u>

To calculate the distance between two places on a mileage chart, simply find the intersection between the column and row of the starting and destination locations.

29.

• First find the distance between Kendal and Middlesbrough, which is the square where the column for Kendal and the row for Middlesbrough meet:

∴ Distance between Kendal and Middlesbrough = 82 miles

• Similarly, find the distance between Middlesbrough and York, which is the square where the column for Middlesbrough and the row for York meet:

∴ Distance between Middlesbrough and York = 50 miles

Now, we can add these distances to find the final answer:

⇒ 82 miles + 50 miles

⇒ 132 miles

30.

• Distance between Nottingham and Leeds = 73 miles

• Distance between Leeds and Hull = 61 miles

Adding these together:

Total distance = 73 miles + 61 miles

                       ⇒ 134 miles

31.

• Distance between York and Lincoln = 81 miles

• Distance between Lincoln and Leeds = 73 miles

Adding these together:

Total distance = 81 miles + 73 miles

                       ⇒ 154 miles
