The table below gives percent of flights that were delayed and on time during good and bad weather.

Good weather Bad Weather

Delayed 7.5% 17.5%
On Time 42.5% 32.5%

Given these percentages, during bad weather, is it more likely that your flight will be delayed or on time? How much more likely?

More likely: on time

By 0.3 or 30%

Step-by-step explanation:

Bad weather is column 2

P(delayed) = 17.5/(17.5+32.5)

= 17.5/50 = 0.35

P(on time) = 32.5/(17.5+32.5)

= 32.5/50 = 0.65

0.65 - 0.35 = 0.3

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
