Answer:
C
Step-by-step explanation:
x = -1 and -7
The value of the y coordinate of any point on the x axis is always 0.
<u><em>Explanation</em></u>
Suppose, the co ordinate of any point is .
It means, the distance of the point from x-axis is '' and distance from y-axis is ''.
Now if the point lies on the x-axis, that means the distance of the point from x-axis will be 0. Thus, the value of '' will be 0.
So, the value of the y coordinate of any point on the x axis is always 0.
The driver's tip was $1.45 because the trip cost $8.55 (2.25+1.5+1.5+1.5+1.5+ 0.3) and Eric gave the driver $10 so to find how much the driver got tipped, you need to subtract 8.55 from 10 so $10 - $ 8.55 = $1.45
Answer:
b. False
Step-by-step explanation:
P(X & Y) = 0.77 + 0.65 - 0.9 = 0.52
P(X) × P(Y) = 0.65×0.77 = 0.5004
Since P(X&Y) and P(X)×P(Y) are not equal, they are not independent
