Answer:
4 is included in the domain
Step-by-step explanation:
The answer is 9. you start with 1+2 in the parenthesis and then divide 6 by 2. that gives you 3x3 which is 9
Answer:
Brand 1 Brand 2 Difference
37734 35202 2532
45299 41635 3664
36240 35500 740
32100 31950 150
37210 38015 −805
48360 47800 560
38200 37810 390
33500 33215 285
Sum of difference = 2532+ 3664+740+150 −805+ 560 +390 +285 = 7516
Mean = 
Mean = 
a) d= 939.5
=1441.21
b)SD= 1441.21
c)Calculate a 99% two-sided confidence interval on the difference in mean life.
confidence level =99%
significance level =α= 0.01
Degree of freedom = n-1 = 8-1 =7
So, 
Formula for confidence interval 
Substitute the values

To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.
2. Therefore, let's call
x: the smaller one.
y: the larger one.
3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:
x+y
4. So, the area of the room is:
(x+y)(x+y)
(x+y)</span>²
Therefore, the answer is: (x+y)²
Answer:
The value of b would be $25 since it's the initial amt. The value of m would be $8. The equation would be y=8x+25
