A rug layer can put down 7/8 square yard of carpeting in 1/20 hour. What is the unit rate in square yards per hour?
Answers
Answer:
17/5 sq yd per hour
Step-by-step explanation:
7/8 sq yd per 1/20 hr = x sq yd per 1 hr
We can set up equivalent proportions and cross-multiply.
\(\frac{ \frac{7}{8} sq yd}{\frac{1}{20}hr}= \frac{x sq yd}{1 hr}\)
7/8 × 1 = 1/20 × x
7/8 = 1/20 x
Multiply both sides by 20.
x = 7/8 × 20
= 140/8
= 35/2
x = 17.5 sq yd
Answer:
Step-by-step explanation:
7/8 divided by 1/20
= 17.5 hours

Khalid and Jesse took different overnight trains.
The graph shows the relationship between the total distance Khalid traveled and the time in hours.
The distance Jesse traveled after x hours is given by the equation y = 150x. Who, if anyone, traveled at a faster speed?
Khalid’s rate is (120, 140, 150 or 280) miles per hour.
Jesses rate is (120, 140, 150 or 280) miles per hour.
So (Jesse, Khalid or Neither)'s train traveled at a faster speed.

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.

2B. Derek makes 10 bracelets in 5 hours.
Step-by-step explanation:
Question 1An ordered pair is a pair of two numbers written in a specific order (x, y), representing the coordinates of a point in a two-dimensional plane.
To write the ordered pairs of each point in the given table, take the x-value from the first column and the y-value from the second column from each row, and write them as an ordered pair (x, y) in the third column:
\(\begin{array}{|c|c|c|c|}\cline{1-4}&\textsf{x-coordinate}&\textsf{y-coordinate}&\sf Ordered\\&&&\sf Pair\;(x,y)\\\cline{1-4}\sf A&4&9&(4,9)\\\cline{1-4}\sf B&6&3&(6,3)\\\cline{1-4}\sf C&1&3&(1,3)\\\cline{1-4}\sf D&8&7&(8,7)\\\cline{1-4}\sf E&8&9&(8,9)\\\cline{1-4}\end{array}\)
To plot each ordered pair on a coordinate plane, locate the x-value of each point along the x-axis, and then move vertically until you reach the the y-value of the point. Mark the point with a dot and add the corresponding label. (See the first attachment for the completed graph).
\(\hrulefill\)
Question 2Part AWe are told that Derek can make 2 bracelets in 1 hour. Therefore, his rate is 2 bracelets per hour. So, he can make 4 bracelets in 2 hours, 6 bracelets in 3 hours, and 8 bracelets in 4 hours. Add this information to the given table:
\(\begin{array}{|c|c|c|}\cline{1-3} \textsf{Time in hours}&\textsf{Total Number of}&\sf Ordered\\\textsf{(x-coordinate)}&\sf Bracelets&\sf Pair\;(x,y)\\&\textsf{(y-coordinate)}&\\\cline{1-3}1&2&(1,2)\\\cline{1-3}2&4&(2,4)\\\cline{1-3}3&6&(3,6)\\\cline{1-3}4&8&(4,8)\\\cline{1-3}\end{array}\)
Plot the ordered pairs on the coordinate plane and join them with a line. (See the second attachment for the completed graph).
Part BThe point (5, 10) represents the ordered pair (x, y) where x is the time in hours and y is the total number of bracelets Derek makes. So, the meaning of the point (5, 10) is that:
Derek makes 10 bracelets in 5 hours.

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answers
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

combined
Answers
Answer:
40.5 inches
Step-by-step explanation:
I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.
Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.
February and March combined: 8.5+5.1 = 13.6
Since the question asked how much more, that means you subtract:
26.9 - 13.6 = 13.3
