Answers:
1: y = 1x + 0.5
3: the y-intercept shows that the original data began above 0 and has had a steady increase since. (not sure abt this one)
4: I'm sorry i don't know this one
5: the data collection shows that the height to arm span has a ratio of 1 throughout you can tell this by using the line of best fit.
6: according to the line of best fit the height of the person will also be about 66 inches.
7: according to the line of best fit the arm span will also be about 74 inches.

Answer:
Step-by-step explanation:
Given that there are two vectors U = (-8,0,1)
V = (1,3,-3)
To find projection of u on V and also projection of V on U
First let us find the dot product U and V
U.V = 
Projection of U on V =
Similarly projection of V on U
=
Julia has 1.44 and Ana has 5.76
7.20
1.44
(2 − 3i) + (x + yi) = 6
We add the left hand side
(2+x) + (-3+y)i = 6
6 can be written in a+ib
6 can be written as 6 + 0i
(2+x) + (-3+y)i = 6 +0i
Now we frame 2 equations
2 + x= 6
-3 + y =0
Solve the first equation
2 + x = 6
Subtract 2 from both sides
x = 4
solve the second equation
-3 + y =0
Add 3 on both sides
y= 3
So x+yi is 4+3i
