Answers
Answer:
2) 4
3) 8
Step-by-step explanation:
Part 2:
= \(\displaystyle \frac{1}{3}\)
Multiply the numerator and denominator by 4
= \(\displaystyle \frac{1 \times 4}{3 \times 4}\)
= \(\displaystyle \frac{4}{12}\)
So, 4 will be placed in the empty box.
Part 3:
= \(\displaystyle \frac{2}{3}\)
Multiply the numerator and denominator by 4
= \(\displaystyle \frac{2 \times 4}{3 \times 4}\)
= \(\displaystyle \frac{8}{12}\)
So, 8 will be placed in the empty box.
\(\rule[225]{225}{2}\)

B. Where can you see the cost per pound of bananas in the graph? What is this amount?
C. Is the relationship shown in the graph a direct variation? How can you tell?
Answers
Answer:
A. The 4 represent pound of bananas and 2.32 represent cost.
B. You can see the cost per pound of bananas in the y-axis.
C. No because one variable isn't equal to the constant time of the other.

One survey estimates that, on average, the retail value of a mid-sized car decreases by 8% annually. If the retail value of a car is V dollars today, which expression represents the car’s value 1 year later?
Answers
Percentage by which the average value of mid sized car decreases each year = 8%
Retail value of a car today = v dollars
Amount of decrease in the value of the car after 1 year = (8/100) * v
= 2v/25 dollars
Then
The equation that represents the value of the car after 1 year = v - (2v/25) dollars
= (25v - 2v)/25 dollars
= 23v/25 dollars
So following this expression the value of the mid sized car can be easily determined after 1 year. I hope this is the answer you were looking for and the procedure is also clear to you.

You borrow $10,000 to buy a car. The simple interest rate is 3%. You pay the loan off after 6 years. What is the total amount you paid for the loan?
Answers
Answer:
The total amount of money needed to pay off the car after 6 years would be $11,800.
Step-by-step explanation:
Write down the facts:
The car costs $10,000The interest rate is 3%And you finished paying the loan off after 6 yearsInterest = $10,000 * 0.03 * 6
This being $10,000, 3% interest rate and over 6 years.
Interest= $1800
This amount we found is the additional amount (interest) you have to pay with the $10,000. Now, to find the total amound we add the interest and $10,000.
Total amount = 10,000 + $1800
Total amount = $11,800
Therefore the total amount paid over 6 years (including the 3% interest rate) would be $11,800. I hope this helped!!!
$11800 is the answer

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides

Noah’s recipe for sparkling orange juice uses 4 liters of orange juice and 5 liters of soda water. a.Noah prepares large batches of sparkling orange juice for school parties. He usually knows the total number of liters, , that he needs to prepare. Write an equation that shows how Noah can find , the number of liters of soda water, if he knows . b.Sometimes the school purchases a certain number, , of liters of orange juice and Noah needs to figure out how much sparkling orange juice he can make. Write an equation that Noah can use to find if he knows .
Answers
Answer: x = T - 4
T = y + 5
Step-by-step explanation:
a. To find the number of liters of soda water (x) if Noah knows the total number of liters (T) of sparkling orange juice he needs to prepare, the equation can be written as:
x = T - 4
b. To find the number of liters of sparkling orange juice (T) Noah can make if the school purchases a certain number of liters of orange juice (y), the equation can be written as:
T = y + 5
In both equations, x represents the number of liters of soda water, T represents the total number of liters of sparkling orange juice, and y represents the number of liters of orange juice.

If there are 2 red balls, 2 blue balls, and 4 green balls in a pail, what is the probability of pulling out a green ball?
(step-to-step pls)
Answers
Answer:
Step-by-step explanation:
Step 1 is to find the total number of balls in the pail.
There are 8 balls in total
Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.
Since 4 out of the 8 balls in the pail are green, you can write this as 4/8
The last step is to simplify to get 1/2 which in other terms is 50%.
So the probability of you pulling a green ball is 50%

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.

Cell phone company A charges $40 a month, with 500 free minutes and $0.10 a minute after that. Cell phone company B charges $25 a month and all minutes cost $0.05.

B = 25 + .05M
20 minutes a day for 30 days = 600 minutes per month
A(600) = 40+.1(100) = $50
B(600) = 25 + .05(100) = $30
Plan B is less expensive
40+.1(M-500)= 25+.05M
40-25- .1(500) = .05-.1M
.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B
40+.1(200) = $60 under plan A
