Answer:
The standard coordinates of the point are ; ( 0,0 )
Step-by-step explanation:
The standard coordinates of the point are ; ( 0,0 ) also the standard values of the means will also be ( 0, 0 )
This is because for the Positive Z-equal line, Negative Z-Equal line and Regression line to all pass through the same point indicates dependent and independent variables of the Z-score and regression lines respectively
Answer:
45 girls
Step-by-step explanation:
If 60% of the class is girls then 40% of the class is boys.
30 boys are in the class, meaning that 40% of the class comprises those 30 boys
First, we need the total number of class members: 30/x = 40/100 -> 40x=3000 -> x=3000/40 -> x=75
Now that we know the total class members, at 75, we can calculate the number of girls in the class. You can do this:
0.6*75=45
or
60/100=x/75 and solve for x
9514 1404 393
Answer:
no solution (parallel lines)
Step-by-step explanation:
You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...
The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
By answering the question and reading the question
Imani=i
Miguel=m
i=2m+3
i+m=87
i=-m+87
2i=m+90
i=(m+90)/2
2m+3=(m+90)/2
2m+3=m/2+45
4m+6=m+90
3m+6=90
3m=84
m=28
Hope this helps :)
