Use the given times and velocities to make two points: (1,4) and (2,2)
Part A:
Slope is the change in Y over the change in X from the two pints you made:
Slope = (2-4) / (2-1 )= -2
Now you have the slope, calculate the Y-intercept
y = -2x + b
Using (1,4)
4 = -2(1) + b = 4 =-2 +b. b = 6
Equation is: y = -2x+6
Part B:
using the above equation replace x with 1, 2, 3, and 4 and solve for the Y
then plot those onto a graph
Answer:
69
Step-by-step explanation:
420 - 69 = 69
Answer:
Step-by-step explanation:
We can treat 20v as a regular number and not a term.
To simplify this square root, we need to break it down into parts which can be squared.
Square root of 4 is 2, so that goes outside the radical.

Answer:
850000
Step-by-step explanation:
0\/4,round down.
5/\9,round up
A simple event is the one which has only one possible outcomes, hence such an event does not involve addition or multiplication of probabilites.
The option B gives only such a probability which can represent a simple event. The rest of the options belong to the compound events as they are sum or product of probabilities.
So, the correct answer is option B
