A survey of 100 randomly selected high school students determined that 51 play organized sports. (a) What is the probability that a randomly selected high school student plays organized sports? (b) Interpret this probability.

(a)0.51

Step-by-step explanation:

Total number of Selected Students =100

Number who play organized Sports=51

We are to determine the Probability that a student selected at random plays organised sports.

Probability=Number of Required Outcome ÷ Total Number of Outcome.

(a) P(a student plays organised sports)=51÷100=0.51

(b)A probability of 0.51 means that there is a 51% chance that a student selected at random plays organised sports. The chances a just a little higher than the probability that a student does not play organized sports.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

24+x=y
