Answer: 23 feet
Step-by-step explanation:
The question simply means that we should calculate the radius of the circle. In this case, the area has been given to be 1661ft².
Area of a circle = πr²
πr² = 1661ft²
3.14(r²) = 1661
r² = 1661 / 3.14
r² = 528.98
r = ✓528.98
r = 23
The solution is 23 feet.

Complete question is;
About 130,000 high school students took the AP Statistics exam in 2010. The free-response section of the exam consisted of five open-ended problems and an investigative task. Each free-response question is scored on a 0 to 4 scale (with 4 being the best). For one of the problems, a random sample of 30 student papers yielded the scores that are graphed in the dot plot attached. The mean score for this sample is x¯ = 1.267 and the standard deviation is s = 1.230.
(a) Find and interpret the standard error of the mean.
(b) Construct and interpret a 99% confidence interval to estimate the mean score on this question. Use the four-step process.
Answer:
A) SOE = 0.225
The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225
B) CI = (0.648, 1.886)
The interpretation of this is that;
We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010
Step-by-step explanation:
A) We are given;
sample mean; x¯ = 1.267
Sample standard deviation; s = 1.230
Sample size; n = 30
Formula for standard error of the mean is;
SOE = s/√n
SOE = 1.23/√30
SOE = 0.225
The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225.
B) we have a sample size of n = 30.
Thus;
DF = 30 - 1 = 29
We want to do a 99% Confidence interval.
From the attached t-table, we can see that critical t-value for DF = 29 and CL of 99%, we have t = 2.756
Formula for CI is;
CI = x¯ ± t(s/√n)
CI = 1.267 ± 2.756(1.23/√30)
CI = 1.267 ± 0.619
CI = (0.648,1.886)
The interpretation of this is that;
We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010.

Find the Mean, Median, and Mode
mean is the average and can be calculated by adding the scores and then dividing by the total number of scores.
for this take the total number of childrena and divide by the number of families which should give 3.5.
median is the middle number when the scores are put in order.
an easy way to find it from this data set is to just add the number of families from top down and bottom up and seeing where they meet which should be 3.
mode is the number that occurs the most in a data set.
for this data set it would be where the greatest number for number of families is which is 3 as there is 82 families.

The function g(x) = 3 |x| is a transformation of the absolute value parent
function. Which graph shows g(x)?
Using translation concepts, the graph that shows the function g(x) = 3|x| is graph B.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Function g(x) = 3|x| is a vertical stretch of 3 units of function f(x) = |x|, that is, they keep the same vertex at (0,0), just graph g is stretched, passing at (1,3) instead of (1,1) for example, hence graph B is correct.

The volume of a cylinder is 756 cm3 . the radius of the base of the cylinder is 6 cm .
what is the height of the cylinder ?
The height of the cylinder is _ cm .
(Simplify your answer .)
Step-by-step explanation:
volume of a cylinder =xr^2h
756=22/7×6^2h
756=22/7×36h
756=113.142h
756/113.14=h
h=6.7cm

How is the product related to the factor? 3/5 x 6/7 The product is less than 3/5 The product is greater than 6/7 The product is greater than 3/5 The product is equal to 3/5
Answer: The product is less than 3/5
Step-by-step explanation:
To know the solution, we have to multiply 3/5 by 6/7. This will be:
= 3/5 × 6/7
= 18/35
Note:
18/35 to decimal = 0.5143
3/5 to decimal = 0.60
6/7 to decimal = 0.8571
Therefore, we can see that the product is less than 3/5.
Write a numerical expression for this number.

Naudia rode her bike two miles south. Then, she went east for three miles. How far is she from her starting point? Round your
answer to the nearest tenth.
Naudia's distance from her starting point will be 3.60 miles.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given that Naudia rode her bike two miles south. Then, she went east for three miles.
The distance will be calculated by using the Pythagorean formula.
c² = a² + b²
c² = 2² + 3²
c² = 4 + 9
c = √13 = 3.60
Therefore, Naudia's distance from her starting point will be 3.60 miles.
