Answer:
$16.80
Step-by-step explanation:
20/100 = 0.20
14 x 0.20 = 2.8
14 + 2.8 = 16.8
substitute y = 3x-12 into -4x + 3y = -11
-4x +3 (3x-12) = -11
distribute
-4x +9x-36 = -11
combine like terms
5x - 36 = -11
add 36 to each side
5x = 25
divide each side by 4
x = 5
noe we need to find y
y = 3x -12
y = 3(5) -12
= 15 -12
y = 3
answer (5,3)
Answer:
Step-by-step explanation:
each of the 6 number has a 1/6 chance of being rolled
1 2 3 4 5 6
1/6 1/6 1/6 1/6 1/6 1/6
Every time the cube is rolled there is a 6/6 chance of any number comes up
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1
What is the probability of NOT rolling a 2? Any other number
1 2 3 4 5 6
1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333
