The dot plots below show the test scores of some mathematics students and some science students: Two dot plots are shown one below the other. The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score? The mathematics students The science students Both groups are similar. Not enough information is available to draw a conclusion.
Answer:
Science students
When you find the average both plots using median, mean, or interquartile range, you will find that the score for the science students will always be greater than the score of the mathematics students. This is because none of the mathematics students scored higher than the science students, so the mean will always be greater.
MATHEMATICS :
Plot interval = 30 to 50
MEAN :
(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324
Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9
Mean = 324 / 9 = 36
BOTTOM :
SCIENCE :
MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =
406
SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9
406 / 9 = 45.111

The distance from your front door to the mailbox is 18 4/5 meters. The distance from your front door to your basketball hoop is 13 7/10 meters. How much farther from your front door is the mailbox than the basketball hoop?
Answer:
5 1/10 meters
Step-by-step explanation:
18 4/5 can be changed to 18 8/10 so
18 8/10 - 13 7/10 = 5 1/10 meters

Hii! Please helpppp!! This was due like 3 days ago lol
Fergus has 3 1/4 cups of oats
= 13/4 cups of oats
Oatmeal bars = 2 2/3
= 8/3 cups of oatmeal used
Therefore cups of oats left = 13/4 - 8/3
= 39/12 - 32/12
= 7/12 cups of oats left
She borrowed 1 cup of oats from neighbour
7/12 + 1/1
= 7/12 + 12/12
= 19/12 cups of oats
Blueberry oats muffin = 1 3/4 cups of oats
= 7/4 cups of oats
Total she will have now = 19/12-7/4
= 19/12 - 21/12
= - 2/12
= -1/6
Which means she needs 1/6 cup of oats more
Therefore its option 4

What is the value of the expression shown below? 7 + (10 - 4 )^2 divided 4 x (1/2)
Answer:
43 / 2 = 21 1/2 = 21.5
Step-by-step explanation:
7+(10-4)^2/ 4 (12) you can either multiply by 4(1/2)/4(12) or do the following
Subtract 4 from 10 to get 6.
7+6^2 / 4×( 1/2)
Calculate 6 to the power of 2 and get 36.
7+36 / 4×( 1/2 )
Add 7 and 36 to get 43.
43 / 4× 1/2
Multiply 4 and 1/2 to get 2.
43 / 2 = 21 1/2 = 21.5

The sum of two consecutive integers is -92. Find the integers.
Answer:
x = -46.5
x + 1 = -45.5
Step-by-step explanation:
x + x + 1 = -92
2x + 1 = -92
-1 -1
------------------
2x = -93
---- ----
2 2
x = -46.5
x + 1
(-46.5) + 1
-45.5
Answer:
No solution
Step-by-step explanation:
We can set up an equation where x is the integer and x+1 is the next one
x+x+1=-92
2x+1=-92
2x/2=-93/2
x=-46.5
-46.5+1=-45.5
The problem is that integers do no include decimals so there is no possible whole number. This problem would be possible if it was consecutive odd integers.

A circle is cut from a square piece of cloth, as shown:
A square, one side labeled as 42 inches has a circle inside it. The circle touches all the sides of the square. The portion of the square outside the circle is shaded.
How many square inches of cloth are cut from the square? (π = 3.14)
131.88 in2
168.00 in2
1,384.74 in2
1,764.00 in2
Answer:
A
Step-by-step explanation:
I think you are supposed to do is 42x3.14=131.88 so the answer is 131.88
hope this helps :)
Answer:
Step-by-step explanation:
Given the choices of answers we have to consider that:
The cloth is cut from the square = Area of circle
Area of circle = π r² = 3.14 * 21² = 1,384.74 in²

please mark me as brainliest and correct me if im wrong
You could either use the propotional method or unitary method, but I am going to be using the porpotional method since it is more quick.
Step 1
So first we would convert the numbers givin into a fraction by putting 5 over 140 and 20 over x which is the question mark.
Step 2
Then we would cross multiply, so multiply numbers that are diagonal to each other .140 would multiply with 20 and 5 would multiply with x.
Step 3
After we multiply (we do not multiply 5 with anything so it is just 5)we would have the equation , x times 5=2800. Since we need to isolate x we would take 5 and put it under 2800 so it would be 2800 divided by 5.
Step 4
After we divide 2800 by 5 we would have 560 which equals to x , making it the ounces needed to feed 20 animals at the shelter .
Summarise
To briefly explain this the way to find the answer would be 20x40 divided by 5.
Hope this helped :D
Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers
1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number
Answer:
option 3.
Step-by-step explanation:
alright, ima explain each option.
1. "smallest odd numbers" 2 is an even number. that's out of the playing field.
2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.
3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]
4. they do multiply to 30, but this does not help break the composite numbers down.
5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.

My neighborhood is full of one-way streets. To drive from my house to the grocery store, I have to go 1 block south, then 1 block east, then 5 blocks north, then 2 blocks east. Each block is 1/16 of a mile. How much shorter would my trip be if I could fly like a bird (that is, travel in a straight line)?
I FOUND THE distance for non bird which is 9/16. I wanna apply the pythagoreum theorum and draw a straight line to make it a triangle so I can do so but don't know where to place it
