Well there is a total of 20 different outcomes and you can only get a sum of 7 four times and 11 once so in total 5 times out of 20 so that is 5 to the twentieth place beyond the decimal but you can round that up to 0.5%.
His final answer would be A. 0.0045
Vertical angles are congruent.
Answer: Ashley spent $18.70 and the friend spent $17.16
Step-by-step explanation:
Original cost of Ashley's meal = $ 15.85
tip left = 18% of 15.85
that is
tip left = 0.18 x 15.85 = $2.85
All together, Ashley will pay
$15.85 + $2.85
= $18.70
The friend's original cost = $14.30
tip = 20% of 14.30
= 0.20 x 14.30
= $2.86
All together , the friend will pay
$14.30 + $2.86
=$17.16
Therefore:
Ashley spent $18.70 and the friend spent $17.16
The equation is positive, so the graph should be on the other side. One way to check this would be to plug a number in the equation,
where x = -2
y= 3/2(-2)-1
y= -3-1
y= -4
on the graph you plotted you have y = 2 where x = -2
