Answer:
Class second have higher score and have greater spread.
Step-by-step explanation:
For first box plot
For second box plot
First class has greater minimum value, it means first class has lower grades.
First quartile of both classes are same, it means equal number students in both classes have less than 62 marks.
First class has greater median.
second class has greater third quartile.
Second class has greater Maximum value. It means second class have higher score than first class.
Second class has greater range. It means the data of second class has greater spread.
Second class has greater inter quartile range. It means the data of second class has greater spread.
Therefore, the class second have higher score and have greater spread.
I did this problem last year, if I remember you do this:
64 pounds of gravel and <span>108 pounds of mulch will be the outcome
</span>
*2 1/4 will be equal to 2.25
*1 1/3 will be equal to 1.33
------------------------------------
2.25 / 1.33 = 1.7 is fine (rounded up)
------------------------------------
*ratio of gravel = 1.7: 1
------------------------------------
FOR MULCH:
1.7/2.7 from 172 you will use the outcome 0.629 * 172 to get 108.2 pounds
------------------------------------
FOR GRAVEL:
172 - 108.2 = 63.8 pounds
------------------------------------
Totals sold will be:
- 108 Pounds
- 64 Pounds
Answer:
Answer below
Step-by-step explanation:
The y-intercept is 2, so you know that one point will be (0,2). The slope is 2/3 so you go 2 units up and 3 units to the right from (0,2).
Answer:
37
Step-by-step explanation:
-3 ^2 = 9
9 * 5 = 45
45 - 8 = 37
7x-5y=21 when x=4 from the coordinate point of (4,y)
Next,
7x-5y=21
Substitute x with 4
7(4)-5y=21
28-5y=21
Add 5 to each side
28-5y+5y=21+5y
28=21+5y
Subtract 21 to each side
28-21=21+5y-21
7=5y
Divided 5 to each side
7/5=5y/5
y=7/5
Or
y=1 2/5
Check:
7x-5y=21
Substitute x with 4 and y with 7/5
7(4)-5(7/5)=21
28-7=21
21=21. As a result, (4,7/5) is your correct answer. Hope it help!
