Help!!!! the integer that makes the following addition sentence true.
? + (-11) + 12 + =-16
Answers
As you can see the end result will end up with -16
Answer:
-17
Step-by-step explanation:
I will represent the question mark with the variable \(x\).
\(x - 11 + 12 = -16\)
To solve for \(x\), we need to isolate it.
To do this, subtract 12 from both sides.
\(x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28\)
Then, add 11 to both sides.
\(x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17\)
\(x = -17\)
So, the integer that makes the equation true is -17.

Step-by-step explanation:
The way to solve for this is to use the formula
Combination C (n-1, r-1)
= n = 5 identical fruits
r = 3 bowls
So, we have: 5 - 1 = 4
3 - 1 = 2

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.

The ratio x:y is 3: 1 Which of the following statements is correct? A x is 3/4 of y B y is 1/3 of x C x is 1/3 of y D y is 1/4 of x
Answers
Answer: i say B is correct
Answer:
B --> y is 1/3 of x
Step-by-step explanation:
x:y is 3:1
=> x is bigger than y
=> x is 3x bigger than y
=> x = 3 lots of y
=> \(x = 3y\)
=> \(\frac{x}{3} = y\)
=> \(\frac{1}{3} x = y\)
Therefore y is \(\frac{1}{3}\) of x
This means that B is correct

Answer:
The solution to the equation (1/2)c - 8 = 4 is c = 24.
Step-by-step explanation:
To solve the equation:
(1/2)c - 8 = 4
We want to isolate the variable c on one side of the equation, so we need to perform inverse operations to both sides of the equation to simplify it.
First, we add 8 to both sides of the equation:
(1/2)c - 8 + 8 = 4 + 8
Simplifying the left side by canceling out -8 and +8:
(1/2)c = 12
Next, we multiply both sides of the equation by 2 to eliminate the fraction:
2 × (1/2)c = 2 × 12
Simplifying the left side by canceling out 2 and 1/2:
c = 24
Therefore, the solution to the equation (1/2)c - 8 = 4 is c = 24.

A middle school club is planning a homecoming dance to raise money for the school. Decorations for the dance cost $100, and the club is charging $10 per student that attends.
Which graph describes the relationship between the amount of money raised and the number of students who attend the dance?
Answers
The amount of money raised and the number of students who attended the dance will be directly proportional to each other, meaning both are positively dependent on each other. This type of a relationship is called a linear relationship, which can be represented by a type of graphical method called the "linear graph".
To accurately represent the data, on the x axis you need to plot the the number of students attending the dance; and on the y axis you need to plot the amount raised and you'll obtain a positive slope of 10.
The starting point of the graph would have the coordinates (0,100) or x = 0 and y = 100, because even if there are no students attending the event, the decoration cost of 100 dollars would still have to be paid.
The equation for the same should be written as: Amount of money raised = 10 x no. of students + 100

Ms. Ramirez deposited $2,720 into an account that earns 2.35% simple interest annually. She made no additional deposits or withdrawals. What will be the balance in Ms. Ramirez's account in dollars and cents at the end of 6 years?
Answers
Answer:
Ms. Ramirez's account balance at the end of 6 years will be $3,094.20.
Step-by-step explanation:
To calculate the balance in Ms. Ramirez's account, we can use the following formula:
Balance = Principal + Interest
In this case, the principal is $2,720, the interest is 2.35%, and the time is 6 years.
Plugging in these values, we get:
Balance = $2,720 + (0.0235 * $2,720 * 6) = $3,094.20
Therefore, Ms. Ramirez's account balance at the end of 6 years will be $3,094.20.
