It is equal. .21 ia the same as 21%
Well i bevel that you r cool an dcan answer it by your self <span />
Let`s assume that points M, N and P are the touching points of those 3 circles:Then:Y M + M Z = 14,Z N + N X = 20X P + P Y = 18And also: M Z = ZN, Y M = P Y and N X = X P.Now we have a system of 3 equations ( Y M, M Z and X P are the radii of each circle ):Y M + M Z = 14M Z + X P = 20X P + Y M = 18 Y M - M Z = - 14+X P + Y M = 18 X P - M Z = 4Y M - M Z = - 14+M Z + X P = 20 X P - Y M = 6 /* ( - 1 )X P - M Z = 4 X P + Y M = - 6 X P - M Z = 4 Y M - M Z = - 2 Y M + M Z = 14 2 Y M = 12 => Y M = 6M Z - 6 = 2 => M Z = 8X P + 6 = 18
X P = 12
Radii of the circles are: 12, 8 and 6.
Start at -4 and go to the right 6 times on the number line and you should end up with 2
Answer:
question seems incomplete but with the limited information one can deduce that the professor was trying to investigate how students CGPA is affected by the length of period spent on video games.
A
Step-by-step exp
independent variables are constants. they do not change or depend on any other variable.
dependent variables, they do depend on other variables, we call them resulting variables..
