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.

help me please, due today
Answer:
Part A: 0.21
Part B: 50
Step-by-step explanation:
Part A:
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.
Hope this helps!

Answer: 65.94
Step-by-step explanation:
Find the area of the middle circle.
3.14 x 2² = 12.56
Pretend the white area doesn't exist and find the area of the shaded region.
3.14 x 5² = 78.5
Then subtract.
78.5 - 12.56 = 65.94

5/2square __ 12.06 use =, ,inequality
Thanks!
Answer: 15 for the first part
(5/2)² < 12.06 but
If y is supposed to be a factor, like multiply by 2, then
(5/2)²y > 12.06
Step-by-step explanation: substitute 2 for y
20y - 5² = 2
20(2) - 25 =
40 - 25 = 15
__________
(5/2)² = 5²/2²
25/4 = 6.25 . So that is less than 12.06
But if y is supposed to be a factor, like multiply by 2, then
(5/2)²y > 12.06

Answer:
4410.8
Step-by-step explanation:
We don't know the height of the cylinder, but we know the sum. A sphere has an equal radius along all sides towards the center. The radius is half of the diameter, and in this case, the diameter is 12 so the radius is 6. We know that the height must be 6 since it is a semisphere and therefore we will subtract 6 from 41 giving us 35; the height of the cylinder. Now apply the formula πr^2h and we would get 3958.406744. Now we can apply the formula 4/3πr^3 which would give us 904.778642 (remember the RADIUS is 6 which is r and the DIAMETER is 12 which is d.) This value however is for a sphere, not a semisphere, so divide the answer by 2, giving us 452.3893421 and by adding 3958.406744 and rounding to the nearest tenth, we get 4410.8. Hope this helps!

Jason’s tub has a capacity of 2 gallons.
Mark’s tub has a capacity of 20 gallons, Louis’ tub can hold 30 quarts, and Jamie can fill his tub with 50 pints of water.
Which friend has a tub with the greatest capacity?
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.

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?
Answer:
"3S + 4C = 66"
Step-by-step explanation:
(6 + 2 + 14 = 22s)
(8 + 17 + 19 = 44c)
22 + 44 = 66
(The math above are examples)
So, it's "3S + 4C = 66"
