A track coach made a two way table to show his runners gender and running category. Male: Sprints- 16 Middle distance- 11 Long d istance- 9 Female: Sprints- 12 Middle distance- 14 Long distance- 5 To the nearest hundredth, what is the probability that a randomly chosen long distance runner is male?

Answer: Our required probability is 0.134.
Step-by-step explanation:
Since we have given that
Sprints Middle distance Long distance Total
Male 16 11 9 36
Female 12 14 5 31
Total 28 25 14 67
So, the probability that a random chosen long distance runner is male is given by
Hence, our required probability is 0.134.
There are 9 long distance male runners and 5 long distance female runners. This makes a total of 9+5 = 14 long distance runners. Out of this total of 14 long distance runners, there are 9 males. So the probability as a fraction is 9/14 If you need the answer in decimal form, then use a calculator to get 9/14 = 0.642857 which is approximate.

Step-by-step explanation:
You start with the percents: You always start with 100%
100-5=95
Then you multiply
95 x 4
4 is how many votes he received the 2nd time
95 x 4= 380
Then you subtract
380-360= 20

Answer:
37.5
Step-by-step explanation:
so x% of 40 is 15
the equation for that is
x/100 * 40 = 15
40x/100 = 15
multiply 100 on both sides
40x = 1500
divide 40 on both sides
37.5
37.5% of 40 is 15
