A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.
What is the unit rate for canned juice, in cases per minute? Explain how you found this unit rate.
Answer: 50 cases per minute
Step-by-step explanation:
1. Select one of the points on the graph. Let's use (2, 100) in this case.
2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.
3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

Explain why you divide by 2 for triangles and why you divide by 3 for pyramids
Answer:

Answer:
c. 384 square feet
Step-by-step explanation:
First, you must find the total area of the pool and deck combined. Because the deck is 4 feet wide and it wraps around the entire pool, 8 feet can be added to both the length and the width of the pool to get the measurements of the whole rectangle combined.
25+8=33
15+8=23
To get the total area you multiply 33 by 23
33 x 23= 759
Then you get the area of the pool alone by multiplying 15 by 25
15 x 25= 375
Then you subtract the area of the pool from the total area to get the area of the deck
759-375=384
The mean of four numbers is 7. Three of the numbers are 5, 7, and 7. What is the fourth number? Show your work.
Answer:
4th number = 9Step-by-step explanation:
let 4th number = X
mean = 7
observations = 5, 7, 7, X
..............................................
mean = sum of observations ÷ numbers of observations
7 = 5+7+7+X ÷ 4
28 = 19 + X
28 - 19 = X
9 = X
The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7. So, the 4th number would be 9.
How to find the mean value of a data set?The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
[tex]x_1, x_2, ..., x_n[/tex]
, then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7.
let 4th number = X
Mean = 7
observations = 5, 7, 7, X
Mean = sum of observations / numbers of observations
[tex]7 = 5+7+7+X / 4\\28 = 19 + X\\28 - 19 = X\\9 = X[/tex]

The data set shows the individual scoring totals for the players on the losing team in the 2012 NBA Finals.
Answer:
Median: 7.5
Lower Quartile: 1
Upper Quartile: 12.5
Step-by-step explanation:
First, arrange the numbers in numerical order.
0,0,1,2,3,7,8,11,13,16,27,32
Now find the middle of the data set, which is 7.5, because you add the 2 middle numbers (7 and 8) and then divide by 2. So your median is 7.5
Now you need to find the medians of the upper and lower quartiles. Spilt the data set into thirds.
(0,0,1,2),(3,7,8,11),(13,16,27,32)
Now find the medians.
For the lower quartile, the median is 1. For the upper quartile, the median is 12.5 .
Please let me know if this correct!! Have a great day!! :)
