Answer:

a.the average size of a seventh-grade class is larger and varies more than that of a kindergarten class

Step-by-step explanation:

ok so we know the mean and the m.a.d of both data sets, so now all we have to do is analyze the data

so the class ranges for kindergarten is 17-21

and the class ranges for 7th grade is 25-34

here's where i prove 'a' to be the correct answer;

21-17=4

34-25=9

the ranges for 7th grade is 5 more than that of a kindergarten class making 'a' the right answer

**i know i'm not an expert but an ace, i've just been trying to become a genius, sorry :(**

good luck :)

hopefully, this helps

have a nice day !!

Answer: you got this try your best

Step-by-step explanation:

Answer:

Step-by-step explanation:

1 - a) I can't see it clearly but if it's: 2/3 × 2/4 it will be 2/3 × 1/2 = 3/6 = 1/2

1 - b) 1/2 × 3/8 = 3/16

1 - c) 7/8 × 3/5 = 21/40

1 - d) 2/7 × 5/8 = 10/56

2 - a) 2/3 × 5 = 10/3

2 - b) 4 × 7/8 = 28/8 = 7/2

2 - c) 3/5 × 12 = 36/5

2 - d) 8 × 4/7 = 32/7

3 - a) 3×1/8 × 4 = 3/8 × 4 = 12/8 = 3/2

3 - b) 5 × 7×1/2 = 5 × 7/2 = 35/2

3 - c) 3×2/3 × 6 = 6/3 × 6 = 2 × 6 = 12

3 - d) 10 × 1×2/3 = 10 × 2/3 = 20/3

4 - a) 2×1/2 × 3×1/3 = 2/2 × 3/3 = 1 × 1 = 1

4 - b) 1×1/5 × 3×3/4 = 1/5 × 9/4 = 9/20

4 - c) 2×1/2 × 2×1/2 = 2/2 × 2/2 = 1 × 1 = 1

4 - d) 4×1/3 × 2×3/5 = 4/3 × 6/5 = 24/15 = 8/5

We need to do 90-61, which is 29. X = 29, because the base of 61 and the right of the x is equal to a right angle.

Answer:

x=29 degrees

Step-by-step explanation:

Both angles shown ad up to a 90 degree angle. We can see this because on the adjacent side there is a box indicating that it is a right angle. The three angles add up to 180, thus if we subtract 90 degrees due to the angle on the left of the y axis, the angles on the right of the y axis must add up to 90 as well.

Since the angles on the right must add up to 90, we set an equation to solve for x:

61+x=90(subtract 61)

x=29 degrees

The equation that represents the total number of students in Bryan's

homeroom is m + 8 = 40.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Let, 'm' be the number of students in Bryan's homeroom.

Given, Four more than half of the students in Bryan’s homeroom have tickets to attend the school’s musical which is 20.

Therefore, The equation to find the number of students in Bryan's homeroom is, (1/2)m + 4 = 20.

m + 8 = 40.

Answer:

For 25, the answer is C

Step-by-step explanation:

How I got the answer for 25 is:

To find the mean absolute deviation of the data, start by finding the mean of the data set.

How you do this is first you need to find the sum of the data values, (add all the numbers together) and divide the sum by the number of data values.(and divide that number by how many numbers you added together in the first place)

In this case, we'd be adding 44 + 39 + 47 + 38 + 38 + 41 + 40, and that equals 287. Now we'll divide 287 by how many numbers we added together, which is 7 numbers. 287 ÷ 7 = 41. That's the mean of the data set.

Next, we'll find the absolute deviation of the mean. How we do this is, we find how far away all the numbers are from 41.

44 is 3 away from 41

39 is 2 away from 41

47 is 6 away from 41

38 is 3 away from 41

41 is 0 away from 41

40 is 1 away from 41

So now, we add all of the distances together (3, 2, 6, 3, 0, and 1), and that equals 15! Now we do 15 ÷ 6, which is 2.5 and the reason we're dividing by 6 is because we're dividing by the number of distances we added together. Now, if you look on your worksheet, the closest answer to 2.5 is C, (2.6) so I'd chose that as the correct answer. I hope that helped!
