Answer:
y = 2x - 9
Step-by-step explanation:
Use slope intercept form, y = mx + b
Plug in the slope, x, and y, then solve for b:
y = mx + b
1 = 2(5) + b
1 = 10 + b
-9 = b
Then, plug in b and the slope into y = mx + b
y = mx + b
y = 2x - 9
So, the equation of the line is y = 2x - 9

Answer:
(b) $1.15
Step-by-step explanation:
The expected value is the sum of products of payoff and probability:
$0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05
= $0 +0.25 +0.20 +0.20 +0.50
= $1.15 . . . . expected value of the scratch ticket
Answer:
just insert the x numbers in the calculation.. so for x = - 3 - > (- 3) / 2 +4 = 2.5
Step-by-step explanation:
x - 2 = y 3
and so on
So discount means 33% of £999 is subtracted from £999 so 33% of 999 is 329.67 so to calculate the discounted price 999-329.67
