Answer : 0.55%
Step-by-step explanation:
The complete table related to the answer given above is attached below
using a 0.10 level of significance the percentage of the variance in the Y-values that shows a linear relationship with the X-values = 0.55%
The values for X^2 , y^2 and x*y is determined an entered into a table ( attached below as well )
Answer:
Let v = no. of students in a van
b = no. of students in a bus
5v + 6b = 393 7v + 6b = 411
9 students in each van 58 students in each bus
Step-by-step explanation:
Let v = no. of students in a van
b = no. of students in a bus
School A School B
(1) 5v + 6b = 393 (2) 7v + 6b = 411
Change all the signs in (1) to get -5v - 6b = -393
Add that to (2) 7v + 6b = 411
<u>-5v - 6b = -393</u>
2v = 18
v = 9 students in each van
Substitute 9 in for v in (1) and we get 5(9) + 6b = 393
45 + 6b = 393
6b = 348
b = 58 students in each bus
Multiply 8 to 4x and 7 so it looks like 32x +56=56 then you subtract 56 from to 56 which equals zero. Your equation should look like 32x=0. Divide 32 by 0 which equals 0. X=0
