. a. answers vary b. Yes; the taller the person is, the longer his or her reach. c. The independent quantities were represented by the x-axis, while the dependent _quantities were represented using the y-axis. d. A trend line can generalize the trend in the data. 1-18. a. The graph is in the first quadrant because negative lengths do not exist; the range of the data determines the kind of graph. b. Counting by 10’s makes the graph a reasonable size. c. In this situation, including the origin with the graph is not suggested. It is easier to see the trend line when the data are not bunched together, and this can be done by changing the range of the graph to exclude the origin. d. The graph should include the maximum height (that of Yao Ming) on the x-axis and the height of the tunnel on the y-axis. 1-21. a. b. c. d. e. f. g. h. 1-22. a. –8 b. 29 c

1. Use distributive property

2. Simplify 2 to the 2nd power to 4

3. Simplify 9 to the 2nd power to 81 (4/81)

The answer to the 2nd problem would be C) 3/8.

1. 3/10 * 5/4

2. 3 * 5 over 10 * 4

3. 15 over 10 * 4

4. 15/40

5. 3/8.

What is the property of the equation 3x+5 - 5 = 20-5

Shalnov [3]

Answer:

x=5

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand

3x+5-5=20-5

We move all terms containing x to the left and all other terms to the right.

+3x=+20-5-5+5

We simplify left and right side of the equation.

+3x=+15

We divide both sides of the equation by 3 to get x.

x=5

A __________ contains all the subset of superset. A superset. B proper subset. C null set 2.Positive square root of 1/3 is______

aivan3 [116]

Answer:

i) superset (A)

ii) 0.577 (A)

Step-by-step explanation:

i) A subset is a set which has all its elements contained in another set.

For two sets A and B, if each element of set A is an element of set B, then A is a subset of B.

A superset is a set that houses another set. So if set A is a subset of set B, then B is a superset of A.

Proper subset

For a set (A) to be a proper subset of another (B) every element of A would be in B but there exists at least one element in B that is not in A.

An Empty Set (or Null Set) doesn't have aren't any elements in it. It is empty.

Since every element of the superset is in the superset. Therefore, A superset contains all the subset of superset.

ii) Square root of 1/3 = √⅓

= ± √⅓ = +√⅓ or -√⅓

+√⅓ = +(√1/√3) = +(1/√3)

+√⅓ = +(1/1.7321)

+√⅓ = +0.577

Therefore Positive square root of 1/3 is 0.577 (A)

Dima020 [189]

Answer: 2.36

Step-by-step explanation:

Using the μ=∑[x⋅P(X=x)

U will need to do

2/11 because you have 2 labeled 1

3/11 because you have 3 labeled 2

6/11 because you have 6 labeled 3

Then you will do:

1 x 2/11 = 0.18

2 x 3/11 = 0.5454 = 0.55

3 x 6/11 = 1.63

Then add them all together to find the μ

0.18 + 0.55 + 1.63 = 2.36

Hope that helps, plz put a good rating
