Answer:
25%
Step-by-step explanation:
60% of couples ordered dessert and coffee
20% of the couples ordered dessert but not coffee.
Let x be the total number of couples that ordered dessert.
Let y be the total number of couples that did not order dessert.
Couple that ordered dessert but not coffee = 20% * x
= 0.2x
60 + 0.2x = x
60 = x - 0.2x
60 = 0.8x
x = 60/0.8
x = 75
Total no of couples that ordered dessert and didn't order dessert = 100
x + y = 100
75 + y = 100
y = 100 - 75
y = 25%
the probability that the next couple the waiter seats will not order dessert = 25%

Answer:
y = -2x - 8
Step-by-step explanation:
Slope-intercept form is y = mx + b. Slope is m, and y-intercept is b. To do this, we substitute -2 for m and -8 for b. When we do this, we get y = -2x + -8. We can simplify this to y = -2x - 8.
