Answer:
The 2nd and last options.
Step-by-step explanation:
By looking at the table we know that the 2nd one is an answer for sure.
Also by looking at the table we know that the 3rd and 4th are not true.
put in -1/2 in the function to see if you get -2
1/2(-1/2)+3/2
-1/4+3/2
-1/4+6/4
5/4
So The first one doesn't work either.
Now the last one:
1/2(4)+3/2
4/2+3/2
7/2
So the last one works too.
Hope this helps :)
Answer:
0.708
Step-by-step explanation:
The calculation of the value of the linear correlation coefficient R is shown below:-
Cost Number
9 85
2 52
3 55
4 68
2 67
5 86
9 83
10 73
Value of linear correlation coefficient R is 0.70772136
or
= 0.708
For clarification look at the spreadsheet which has been attached and uses the following steps which are as follows
Step 1
To activate the data analysis option:- Go to file menu click on add-in option and choose the manage option and select Excel Add-in option click on Ok after that choose Analysis Tool Pak
Step 2
After following step 1 choose data tab and select data analysis tab and select correlation and click ok
Step 3
After selecting correlation to select the range from $A$2:$B$9 and then click OK to reach the value of linear correlation coefficient R.
6 = -2b (cancel -2b on both sides)
6/-2 = b (divide both sides by -2)
-3 = b (simplify 6/2 to 3)
now switch sides
Answer: b = -3
-23
2x+2y/2w+3z
2(-5)+2(8)/2(-2)+3(-3)
-10+16/-4-9
-14-9
-23
