Jin’s mother estimates there is a half gallon of fruit punch remaining in the container. There is actually 72 ounces of fruit punch in the container. What is the percent error of Jin’s mother’s estimate, rounded to the nearest tenth?
PLS I NEED HELP ITS DUE IN 10 MINUTES!!!!!!
Answers
Answer: 0.7 I think
Step-by-step explanation:
The percent of error of Jin's mother's estimate is 4,9% (4,9 percent)
The Percent of error of Jin's mother's estimate can be calculated as follows ?
The first step is to convert a half gallon to ounces
1 gallon = 153,722 ounces
= \(\frac{1}{2}\) × 153,722
= 76,861 ounces
The next step is calculate the error between Jin's mother's estimate (76,861 ounces) and the actual amount of fruit punch in the container (72 ounces)
The error = 76,861 - 72
= 4,861
Third step is to round the calculated the percent error to the nearest tenth.
4,861 ÷ 100 = 4,861%
The final step is to round it to the nearest tenth by round the second digit behind the coma which has value more than 5 to the higher number of the first digit behind the coma.
4,861% = 4,9%
Hence, the percent error of Jin's mother's estimate is 4,9% (4,9 percent)

Answer:

Step-by-step explanation:
Simplifying
6x + -7 = 180
Reorder the terms:
-7 + 6x = 180
Solving
-7 + 6x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 6x = 180 + 7
Combine like terms: -7 + 7 = 0
0 + 6x = 180 + 7
6x = 180 + 7
Combine like terms: 180 + 7 = 187
6x = 187
Divide each side by '6'.
x = 31.16666667
Simplifying
x = 31.16666667

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 state of colorado is 4 cm long and 3 cm wide on a map. A cartographer wants to use a scale factor of 2.5 to enlarge the map. What is the area of the enlarged map?
A:12 square cm
B:30 square cm
C:35 square cm
D:75 square cm
Answers
Answer:
D. 75 cm²
Step-by-step explanation:
We are asked to find the area of a scaled map.
What is a Scale Factor?A scale factor is a change in the size, or ratio of a shape, or object.
The value of the scale factor represents how much larger the shape or object will become.
First, let's identify what is given to us.
Given:
The map of Colorado is 4 cm long and 3 cm wide.We have to enlarge the map with a scale factor of 2.5.We should begin by enlarging the map with the given scale factor. In order to find the dimensions of the scaled map, we should multiply the given dimensions of the original map by the scale factor.
Multiply:
\(4 \times 2.5 = 10 \ cm\)
\(3 \times 2.5 = 7.5 \ cm\)
Next, we should find the area of the scaled map by multiply the dimensions together.
\(A = L \times W\)
Multiply:
\(A = 10 \times 7.5\)
\(A = 75 \ cm^{2}\)
The area of the scaled map is D. 75 cm².

well, it was truly 12.5 mL, however she said 13 mL, well, she was off by 13 - 12.5 = 0.5 mL.
Now, if we take 12.5(origin amount) to be the 100%, what is 0.5 off of it in percentage?
\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} 12.5 & 100\\ 0.5& x \end{array} \implies \cfrac{12.5}{0.5}~~=~~\cfrac{100}{x} \implies 12.5x=50 \\\\\\ x=\cfrac{50}{12.5}\implies x=\stackrel{\%}{4}\)
For this problem, it is asking for a percentage error, which is basically how far off the student was from the true value. (But in percentages)
First, we need to find how far off the student was in millimeters, which is calculated by finding the difference between the guess and the true value:
13-12.5=0.5
So the student was 0.5 millimeters off of the total, from here, we can use this number to find our answer.
Percentages also have regular number counterparts. For example, 1 is 100%, because you have one whole thing. 0.5 is 50% because 0.5 is half of a whole number. .33 is 33% etc.
To calculate how far the guess was from the actual amount, we divide the difference (0.5) by the true value (12.5)
0.5/12.5=0.04
0.04 converted to a percentage is 4%. (You move the decimal two places to the left, or multiply by 100)
This works because you can calculate how much a value takes up of the total by dividing. For example, to find out how much 1 takes up of 4, you would calculate 1/4, which equals .25, or 25%, and we know this is true.
I hope this helps!
