Answer:
Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
Two points are given: (-6,4) and (-2,2). Calculating the slope:
The equation of the line is, so far:
To calculate the value of b, we use any of the given points, for example (-6,4):
Solving:
b = 1
The equation of the line is:
We can see none of the choices is correct.
Answer:
$ 1.96
Step-by-step explanation:
Number of spots with outcome of $1 = 9
Number of spots with outcome of $2 = 18
Number of spots with outcome of $10 = 1
Total number of spots = 28
Probability that ball will land on $1 = 
Probability that ball will land on $2 = 
Probability that ball will land on $10 = 
The amount that player should expect to win on average in equal to expected value of the game. Expected value is calculated as the summation of product of probabilities with their respective outcomes.
i.e. for this case:
Expected Value will be:
This means, on average the player should expect to win $ 1.96
It's simply 4,2,0,-2..... the pattern is just subtracting two as you go on.
Original is 100
1/4 off is 25 off
75 left
10% what's left is 75-7.5=67.5
this was already out of 100
100=67.5=32.5
1/4 off and then 10% off is the same as 32.5% discount
