Answer:
Step-by-step explanation:
P (blue) fraction = 2/8 decimal=.25 percent=25%
P(purple) fraction=0/8 decimal=0 percent =0%
P(not green) fraction=5/8 decimal=.625 percent= 62.5%
P(not brown) fraction=8/8 decimal=1 percent =100%
2)Refer to the table on air travel selected airports. Suppose a flight that arrived at <u>El Centro</u> is selected at random. What is the probability that the flight <u>did not arrive on time?</u> write your answer as a fraction, decimal and percent.
80% on time so 20% are not on time
20/100 ÷ 20 =1/5
20%, .2, 1/5

Answer: 7.3
Step-by-step explanation:
To find the distance between these two points, find the difference in the x and y values then square them and add them then finally find the square root of that added number obtained.
5 - 7 = -2
9 - 2 = -7
-2^2 + -7^2 = d^2 where d is the distance
4 + 49 = d^2
53 = d^2
d =
d= 7.2801 rounded to the nearest tenth is 7.3
