Answer:
x=9
Step-by-step explanation:
-9x + 1 = -80
-9x = -81 substract 1 from both sides
x= 9 divide both sides by -9
The two dice have PMFs


The sum of the two rolls can take on 8 different values:

The outcome of either roll is independent of the other, so that

a. Then PMF of
is

b. The histogram is nothing special, same as the discrete uniform distribution over the interval [0, 7].
I hope this helps you
2x+5y+3x-5y=-24+14
5x+0=-10
x=-2
2. (-2)+5y=-24
-4+5y=-24
5y=-20
y=-4
Answer:
$5,376
$47,376
Step-by-step explanation:
Given :
Price of current model = $42,000
Percentage increase in price = 12.8%
Price increase in dollars :
12.8% of $42000
0.128 * $42000
= $5,376
Price of the next model :
Price of current model + increase in price
$42000 + $5376
= $47,376
