On a middle school basketball court, there is a large circle painted on the
floor. The diameter of the circle is 12 feet. What is the area of the circle?
Jse 3.14 for a
Answer:
113.04 feet²
Step-by-step explanation:
Use the circle area formula, A = [tex]\pi[/tex]r²
Sine the diameter is 12 feet, the radius is 6 feet
Plug in 6 as r into the formula, and 3.14 as pi, then solve:
A = [tex]\pi[/tex]r²
A = (3.14)(6²)
A = (3.14)(36)
A = 113.04
So, the area of the circle is approximately 113.04 feet²
Answer:
113.04 feet²

Ali and Jake went on a cross-country
trip. They took a train part of the way,
and took a bus the rest of the way. They
traveled a total of 1100 kilometers,
riding on the train 350 more kilometers
than on the bus.
Let x = kilometers traveled by bus. Let
y = kilometers traveled by train.
Answer:
Let x = Kilometers by bus
then x + (x + 350) = 1100
2x = 750
x = 375 by bus
x - 350 + x = 1100
2x = 1450
x = 725 by train
i hope this helps a little bit

A linguist at a large university was studying the word length of papers submitted by students en
humanities programs. From a random sample of 25 papers, the linguist counted the number of words
used in each paper. The 95 percent confidence interval was calculated to be (20,995, 22,905).
Assuming all conditions for inference are met, which of the following is a correct interpretation of the
interval?
Answer:
We are 95 percent confident that the mean word length for all papers submitted by students in humanities programs is between 20,995 words and 22,905 words
Step-by-step explanation:
The confidence interval is used to predict the mean for the entire humanities program, not just the sample.

Answer:
B
Step-by-step explanation:
Two data sets contain an equal number of values. The double box and whisker plot represents the values in the data set. Compare the data sets using measures of center and variation.
Answer with explanation:
From the box and whisker plot of seventh grade we have:
The minimum value =6
First quartile or lower quartile i.e. = 14
Median or second quartile i.e. = 18
Third quartile or upper quartile i.e. =22
and maximum value = 26
From the box and whisker plot of eighth grade we have:
The minimum value =22
First quartile or lower quartile i.e. = 26
Median or second quartile i.e. = 30
Third quartile or upper quartile i.e. = 34
and maximum value = 38
a)
The overlap of the two sets of data is as follows.
The upper quartile or third quartile of seventh grade is same as the minimum value of the data of eighth grade.
And the maximum value of seventh grade is same as the lower quartile of eighth grade.
b)
IQR is calculated as the difference of the Upper quartile and the lower quartile
i.e.
so, IQR of seventh grade is:
22-14=8
IQR of seventh grade=8
IQR of eighth grade is:
34-26=8
Hence, IQR of eighth grade=8
c)
The difference of the median of the two data sets is:
30-18=12
Hence, the difference of median is: 12
d)
As the IQR of both the sets is same i.e. 8.
Hence, the number that must be multiplied by IQR so that it is equal to the difference between the medians of the two sets is:
Hence, the number is : 1.5

Ann has two more than twice the amount of toffees Mary has. Total number of
toffees among them is 11. (i) Assuming the number of toffees Mary has is x, build up an equation.
Answer:
SO THE EQUATION IS
2 + 2X = 11
1. y-23=55 2. x-14= -8
3. -15 = n + 18 4. 18.3 + a = 2.7
what are the answers for all of these i need help FAST!!!
Answer:
1. y = 32
2. x = 6
3. -33 = n
4. a = -15.6
Step-by-step explanation:
1.
y-23=55
+23 +23 (23 cancels)
y = 32
2.
x - 14 = -8
+14 +14 (-14 cancels)
x = 6
3.
-15 = n + 18
-18 -18 (18 cancels)
-33 = n
4.
18.3 + a = 2.7
-18.3 -18.3 (18.3 cancels)
a = -15.6

Point B has coordinates (4,1). The x-coordinate of point A is -8. The distance between point A and point B is 13 units. What are the possible coordinates of point A?
Answer:
The possible coordinates of point A are (-8,-4) or (-8,6)
Step-by-step explanation:
The distance between two points is given by the formula
[tex]d = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]
For point A [tex](x_{1} , y_{1})[/tex]; [tex]x_{1}= -8[/tex] and [tex]y_{1}[/tex] is unknown
For point B [tex](x_{2} , y_{2})[/tex]; (4,1) i.e [tex]x_{2}=4[/tex] and [tex]y_{2}=1[/tex]
and d = 13
Putting the values into the equation,
[tex]13= \sqrt{[(4-(-8)]^{2} + (1-y_{1})^{2} }\\13= \sqrt{[(4+8)]^{2} + (1-y_{1})^{2} }\\13= \sqrt{12^{2} + (1-y_{1})^{2} }\\13^{2} = 12^{2} + (1-y_{1})^{2} \\169 = 144 +(1-y_{1})^{2}\\169-144 = (1-y_{1})^{2}\\25 = 1 -2y_{1} +y_{1}^{2} \\y_{1}^{2} -2y_{1}+1-25 =0\\y_{1}^{2} -2y_{1}-24 =0\\y_{1}^{2} -6y_{1} + 4y_{1} -24 =0 \\y_{1}(y_{1}-6) +4(y_{1} -6) = 0\\(y_{1}+4)(y_{1}-6) =0\\(y_{1}+4)=0 or (y_{1}-6) =0[/tex]
[tex]y_{1}+4= 0[/tex] or [tex]y_{1}-6 =0[/tex]
[tex]y_{1} =-4[/tex] or [tex]y_{1} = 6[/tex]
Hence, the possible coordinates of point A are (-8,-4) or (-8,6)

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place
Step-by-step explanation:
I think you have forgotten to attach the question.
Anyways....
In order to find the area of a circle use the formula:
π[tex]r^{2}[/tex] Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × [tex]3^{2}[/tex]
Since you have taken pi as 3.142...
3.142 × [tex]3^{2}[/tex]
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3 [tex]cm^{2}[/tex]
