Of the last 6 flights to arrive at Wildgrove Airport, 3 were late. Considering this data, how many of the next 14 flights would you expect to arrive late? *

7 flights

Step-by-step explanation:

To solve this problem we can establish a rule of three using the information that the question gave:

In the last 6 flights, 3 were late, so from the next 14 flights, how many we expect to be late:

6 total flights -> 3 flights late

14 total flights -> X flights late

6/14 = 3/X

X = 14 * 3 / 6 = 7

From the 14 flights, we expect 7 flights to be late.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
