Find the mean absolute deviation of each data set. Use a pencil or paper. What do you notice about the mean of the two data sets

Gnoma [55]

Answer:

Dataset 1 = 3.6

Dataset 2 = 24.8

Step-by-step explanation:

Given the dataset :

Data Set 1: 47, 46, 51, 54, 57

Data Set 2: 15, 25, 51, 77, 87

Mean absolute deviation :

Σ|x - mean| / n

Dataset 1 :

Mean = (47 + 46 + 51 + 54 + 57) / 5 = 51

Mean absolute deviation :

(|47 - 51| + |46 - 51| + |51 - 51| + |54 - 51| + |57 - 51|) ÷ n

(4 + 5 + 0 + 3 + 6) / 5

= 3.6

Dataset 2:

(15 + 25 + 51 + 77 + 87) / 5

Mean = 51

(|15 - 51| + |25 - 51| + |51 - 51| + |77 - 51| + |87 - 51|) ÷ 5

(36 + 26 + 0 + 26 + 36) / 5

= 24.8

Which graph represents the solution set for the inequality 8z≤ 16?

uysha [10]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$8z\leq 16$

Solve for z

Divide by 8 both sides

$z\leq 16/8$

$z\leq 2$

The solution for z is the interval ----> (-∞,2]

All real numbers less than or equal to 2

In a number line the solution is the shaded area at left of z=2 (closed circle)

using a graphing tool

see the attached figure

Answer:x=9

Step-by-step explanation:so this is a isosceles triangle so that means the two sides are equal so set up the equation as 3x-7=20. And by moving the 7 over it will be 3x=27 and then you want you separate the x and to do that you have to divide x and 27 by 3 and you answer is x = 9

The U.S. Senate is composed of 2 senators from each of the 50 states. In order for a treaty to be ratified, at least two thirds

Sholpan [36]

There are 2 senators from each of the 50 states.
All senators are present, therefore there are 100 senators.

48 senators voted in favor of a treaty.
Let x = the number of additional senators who should vote in favor of the treaty to achieve 2/3 of 100.
That is,
48 + x ≥ (2/3)100
x ≥ 200/3 - 48
x ≥ 18.667

x should be an integer, therefore
x ≥ 19

Answer: 19 or greater
