Answer:
$28
Step-by-step explanation:
First, we need to subtract 35 from 120.
120 - 35 = 85
Next, we need to divide 85 by 3 to get our answer.
85 / 3 = 28.333 (repeated)
Therefore, the answer is $28 because she cannot spend over $120 and each sweater costs the same.
Answer the two questions below
3. Suppose that you are going to select a random sample of students from your school, measure the heights of the students in your sample, and then find the mean height for your sample. There are many different sets of students who could end up forming your sample. Will the sample mean be the same for all possible samples? If so, explain why. If not, what is the phrase used for the fact the sample means will vary according to the sample selected?
4. Return to the context of the previous item. The sample mean will vary according to what sample you happen to select. If you want to reduce this variation, would you choose to select a sample of size 5 or a sample of size 25?
Answer:
3: No
4: 25
Step-by-step explanation:
3: It won't because not everyone is the same height and there will be variation in the mean height.
4: A larger sample size will give a more accurate representation of the population, where as a sample size of 5 is much more likely to have a higher percentage of outliers, and each outlier matters much more in finding the mean. In a sample size of 25, each outlier matters much less.

Step-by-step explanation:
Simplifying
41n(7x) = 8
Remove parenthesis around (7x)
41n * 7x = 8
Reorder the terms for easier multiplication:
41 * 7n * x = 8
Multiply 41 * 7
287n * x = 8
Multiply n * x
287nx = 8
Solving
287nx = 8
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '287x'.
n = 0.02787456446x-1
Simplifying
n = 0.02787456446x-1
Evaluate the expression: |8| - 2 x |-3| + 4

Compare the backpack weights for the students in the three classes.
Help! Find the answers and explain the work | max points!
Answer:
1) r = 20.2/2
= 10.1 mm
circumference = ( (1/2) (2) (π) (10.2) )
= 32.04 mm
perimeter = (3.1 + 3.1 + 20.2 + ( (1/2) (2) (π) (10.2) )
= 58.13 mm
2) circumference = (1/4) (2) (π) (307.34)
= 482.77 mm
perimeter = (11.5 + 11.5 + (2 * 10.1) + ( (1/4) (2) (π) (307.34) )
= 525.97 mm
3) circumference = (3/4) (2) (π) (2.5)
= 11.78 cm
4) circumference = (3/4) (2) (π) (2.5)
= 23.56 cm
5) circumference = (1/2) (2) (π) (32)
= 100.53 cm
6) r = 6/2 = 3 cm
circumference = (1/2) (2) (π) (3)
= 9.42 cm
perimeter = (2 + 2 + 6 + ( (1/2) (2) (π) (3) )
= 19.42 cm

this question has had me stumped since Thursday could you help me out?
Answer:
Swewed left
Step-by-step explanation:
I know this because most of the data is on the left and not many on the right. And in the graph the mean is less than the median so by that you can know it's left skewed because left skewed is also known as negative sweked and I use that to help me since less and negative have a link.
A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?
Answer:
192
Step-by-step explanation:
The area of the cereal box = 8 x 3 x 10 = 240
Therefore, if 100% of the box is filled with
cereal, the amount of cereal in the box
will be 240.
now, 80% is x
80/100 = x/240
cross multiplying,
100x = 80×240
100x = 19 200
dividing both sides by 100
x = 192
Answer:
192

A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 212cm. The prism is filled with cubes that have edge lengths of 12 cm. How many cubes are needed to fill the rectangular prism? Enter your answer in the box.
Answer:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes

Answer:
Bro i dont know if i am right but here we go
The answer most likely is 80
Step-by-step explanation:
By useing a bit of geometry instead of useing two angles to find your last angle.
So first notice how there are two of the same sides (14)but one differnt side(18) okay nice
With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.
So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80
I hope you understand and im sorry if this is wrong.

A popular art teacher at a school asks a sample of students if they would be interested in taking an art class next year. Of the 30 students he asks, 85% are in one of his art classes this year. Only 15% of the students in the school are in one of his art classes this year. Will this sample be biased? *
Yes, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
No, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.
Yes, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.

What comes next in this pattern? (add 4/6)
1/6, 5/6, 1 3/6, ...
A.1 5/6
B.2 2/6
C.2 4/6
D.2 1/6
Answer:
D. 2 1/6
Step-by-step explanation:
To visualize the problem easier, start by converting all the fractions to improper fractions, this will allow you to just add the denominators and simplify the question:
1/6, 5/6, 1 3/6 —> 1/6, 5/6, 9/6
Now that the sequence is rewritten, you can simply add 4 to the numerator, which equals 13/6.
Rewrite this again by finding how many times 6 goes into 13, and use the remainder as the numerator of the new fraction, which will end up as 2 1/6.
A Ferris wheel rotates three times when it travels 235.5 feet. Find the diameter of the Ferris wheel. Use 3.14 for pi
Answer:
try 3.14 x 3.14 / 235.5 and that should be your awnser.
Step-by-step explanation:
the equation for diameter is d=2r which is pi times pi divided my the number. if i remeber correctly. lmk if im wrong
Answer: The diameter is 10cm
Step-by-step explanation:
First, we divide 78.5/3.14 which = 25
Now, we find the square root of 25 to find the radius, which is 5.
The radius is 5cm, which means that the diameter is 10cm.
The diameter of the Ferris wheel is 10cm.
If we recalculate the area again with the diameter given, we can see that:
AREA = 3.14r2
AREA = 3.14 x 5 squared ( radius is half diameter )
AREA = 3.14 x 25 = 78.5
