Tw = Time traveled west
Tn = Time traveled north
Tw + Tn = 9 hours
22Tw + 12Tn = 158 miles
Solve the 2 equations and you get
Tw = 5 hours
Tn = 4 hours
12 x 4 = 48 miles traveled north
Equation
Y=P%*X
Y= 25%*75
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 75
Y = 18.75
A)
The relationship between the amount of hours
spent studying and the test scores increase with time in a positive direction showing a positive correlation.
B) Y=8x+40
Y=8(3) +40
Y=24+40
Y= 64
C)
The 40 stands for the initial score the student
can get without any studying
