Based on visual inspection of the dot plots, it appears that Grade 7 has a lower mean score than Grade 8.
What is dot plot?A dot chart, also known as a dot plot, is a type of statistical chart that consists of data points plotted on a relatively simple scale, typically using filled in circles.
Based on a visual examination of the dot plots, Grade 7 appears to have a lower mean score than Grade 8.
In Grade 7, the majority of students scored in the 70s, with fewer scoring in the 50s and 80s, whereas in Grade 8, the majority of students scored in the 60s, with fewer scoring in the 70s, 80s, and 100s.
This suggests that the mean score in Grade 8 is higher.
Thus, this can be concluded regarding the given scenario.

The manager of a student bowling team bought 3 shirts and 4 caps for $66. At another time, he bought 7 shirts and 3 caps for $116 at the same unit prices as for the first purchase.
If S = cost of a shirt and C = cost of a cap, what is one of the equations that can be used to solve the problem?
Answers
Answer:
"3S + 4C = 66"
Step-by-step explanation:
(6 + 2 + 14 = 22s)
(8 + 17 + 19 = 44c)
22 + 44 = 66

Answer:
The measure of angle N is A. 30 degrees
Angle N is similar to angle Y, we can assume this by the way the triangles are named (xYz and mNo).
A triangle's inner angles must equal 180.
Angle Y is 30 degrees because 180-90-60=30.
So angle N is also 30 degrees.

I would recommend a calculator for this.
Start by adding all the candies which would add to 24. Now take the number of yellow candies, 5, and divide it by 24 which would give us 0.2083, but they want it in hundredths which would be 8 rounded to give us 0.21.
Part B:
The best way is to see by what 24 was multiplied by to equal 200, so divide 200 by 24, which would give us a decimal of 8. Now multiply the number of green candies, 6, by our answer and you would get 50.

Which friend has a tub with the greatest capacity?
Answers
Answer:
Mark's Tub is the biggest out of them all at 20 gallons.
Step-by-step explanation:
First, Let's calculate everything into Gallons.
We already know that Jason and Mark's capacities don't need calculations.
Louis's 30 quarts can be calculated to 7.50 Gallons.
Jamie's 50 pints can be calculated to 6.25 Gallons.
Conclusion:
Jason's Tub is the least at 2 gallons.
Jamie's Tub is more than Jason's at 6.25 gallons
Louis's Tub is more than Jamie's at 7.50 gallons.
Mark's Tub is the biggest out of them all at 20 gallons.
Answer:
Mark's tub can hold the most.
Step-by-step explanation:
Jason has 2 gallons.
Mark has 20 gallons.
Louis has 30 quarts, which is basically 7.5 gallons.
Jamie has 50 pints, which is basically 7.50594 gallons.
Mark's tub can hold the most.

Step-by-step explanation:
I think its easier to break it up to find the answer, in doing so, the top rectangle would be 6 units "long", 4 units "tall".
The bottom shape would be 4 units long, and 3 units tall.
*It would be 4 because the two isn't part of the bottom shape, so you would subtract 2 from 6, giving you 4.*
Then you simply multiply:
6x4=24
4x3=12
Now you have the area for both shapes, you would then add them together to get the full shape:
24+12= 36
Therefor: The area is 36 Units. or A.
