]Show all work
Answers
Answer:
38 7/18
Step-by-step explanation:
The LCD of denominators 3, 9 and 2 is 72; all three of these divide evenly into 72. Rewriting the original problem, we get
7 24/72 - 5 64/72 + 8 36/72
Rewriting the original quantities as improper fractions, we get
22/3 - 53/9 + 17/2
Applying the LCD, we get
24(22) 8(53) 17(36) 2764
----------- - ----------- + ---------- = ------------ = 38 7/18
72 72 72 72
\(7\frac{1}{3}-5\frac{8}{9}+8\frac{1}{2}= \frac{22}{3}-\frac{53}{9} +\frac{17}{2} = \frac{132}{18}-\frac{106}{18}+\frac{153}{18} =\frac{132-106+153}{18} =\frac{179}{18}=9\frac{17}{18}\)
ok done. Thank to me :>

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

110:19

$10
Step-by-step explanation:
For 1-8, they are ratios. Ratios can be expressed in many two major ways. Fractions, and the answer i put. Ratio is like division. Therefore, you divide it by something.
Let’s bring question 8 for example,
It says: There are 110 students on a bus filled with 129 people. What is the ratio of students to teachers?
The given fact is that there is 110 students and 129 in total. It means that there is 19 adults, since 129-110 is equal to 19. Then, it’s looking for the ratio of students to teacher. The answer would be 110:19, 110/19, or 110 divided by 19
For question 9, it asks how much oranges Lisa will use if she serves 800 people.
It takes 9/40 oranges per servings. To solve this, we need to multiply 9/40 by 800, which is equal to 180(9/40*800=7200/40=180)
For question 10, we have to find how much it costs for a single ring.
if 5 rings cost $1, it means that it costs $0.2 per ring, since 1/5 is equal to 0.2. Then, we have to multiply it by 50. 0.2 time 50 is equal to 10.
I hoped this helped
I only know these ones tho...
1. 60:13 (You arrange it to the order the question asked in this case they asked for "the ratio of students to teachers" so I did that)
2. 16:56 (You are supposed to add them like this to get the ratio of students 40 + 16 = 56)
3. 11:16 (You arrange them in the order that the question asked for your example was "What is the ratio of calico kittens to non-calico kittens" so I arranged them like that)
4. 10:17 (You are supposed to add them like this to get the ratio of attendees 7 + 10 = 17)
5. 2:7 (What we do is that because they told us there are 2 brindle puppies and we know the number of puppies is 9 so we minus the 2 brindle puppies from 9. To find the amount of non-bridle puppies we do this 9 - 2 = 7)
6. 28:40 (You are supposed to add them like this to get the ratio of attendees to teenagers 28 + 12 = 40)
7. 11:33 (You are supposed to add them like this to get the ratio of total cakes 22 + 11 = 33)
8. 110:19 (What we do is that because they told us there are 110 students and we know the number of people is 129 so we minus the 110 students from 129 to find the ratio of students to teachers we do this 129 - 110 = 19)

Triangle JKL has measures as follows: KJL=(6x-1), JLK=75, LKJ=(11x+4) What is the measures of angle KJL?____________ DOESN'T PROVIDE PICTURE!
Answers
Answer:
Angle KJL is equal to 35 degree
Step-by-step explanation:
Angles KJL are interior angles and so they sum up to 180. Therefore, we will add all the angles which are 6x-1+11x+4+75 and equate it to 180
So it will be 6x - 1 + 11x + 4 + 75 = 180.
So we will get our x to be 6 the we will replace it with the x. So finding angle KJL it will be 6(6)-1 which will give u 35 degree
If you spin the spinner 48 times, what is the best prediction possible for the number of times it will land on pink or green? times
Answers
hope this helps you out & I’m not 100% sure if this is right so sorry if it’s wrong .
The best prediction possible for the number of times it will land on pink or green is 48 times, As the total probability is 1.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, A spinner has 4 pink parts and 2 green parts.
The probability that it would land or pink or green is P(P) + P(G).
= (4/6) + (2/6).
= (4 + 2)/6.
= 6/6.
= 1.
Now, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory. Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.
Therefore, The best prediction possible for the number of times it will land on pink or green is,
= 48[P(P) + P(G)].
= 48(1).
= 48 times.

Step-by-step explanation:
I would first try to get that fraction into x/100 because 100 is the easiest to work with.
In order to get from 40 to 100, you multiply by 2.5
So we should multiply 29 by 2.5 also to make it evened out.
29 x 2.5 = 72.5
72.5/100
Now we will move the decimal two places to the left on both sides because 100. is the same as 100
72.5/100. turns into .725/1
The closest thing to .725 is .7

The perimeter is __ units.
The area is ___ square units.
Answers
Answer:
Step-by-step explanation:
TU , UV , VW, TW are the sides
As points T and U have same x-coordinate, length of TU will be given by the difference of y-coordinate
TU = 9 - 7 = 2 units
As points U and V have same y-coordinate, length of UV will be given by the difference of x-coordinate
UV = 5 - 2 = 3 units
As points V and W have same x-coordinate, length of VW will be given by the difference of y-coordinate
VW = 9 -7 = 2 units
As points W and T have same y-coordinate, length of WT will be given by the difference of x-coordinate
WT = 5 - 2 = 3 units
TU = VW = 2 units
UV = WT = 3 units
So, TUVW is a rectangle
Area = length *width = 3* 2 = 6 square units
Perimeter = 3 + 2 + 3 + 2 = 10 units
