Suppose you are running a racing tournament with 12 horses. All eligible horses run in the race at once, and after the first rac
borishaifa [10]

Answer:

a)  66

b)  45

Step-by-step explanation:

We have 12 horses and after the first race 2 of them have to be eliminated

that condition is equal to consider that 10 horses will be available for the second race.

The number of possiblities we have for the first race is the combination of 12 horses in group of 10

C¹²₁₀   =  12!/ (2!)* (12-2)!   =  12*11/2   = 66

For the second race

C¹⁰₈  = 10! / 8! * (10-8)!   =   10*9/ 2   = 45

LiRa [457]

Answer:

The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.

Step-by-step explanation:

We take the estimate from the website, and expand for all buyers, to find the proportion that use their smartphones.

400 users of the website were randomly sampled from the existing database and 180 were found to have used their smart phones.

180/400 = 0.45

The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.

Can someone please help me with # 2 #13 thanks show work how it's done, please
zavuch27 [327]

Problem 13

10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get

10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q

so we get the original expression again. Here 10 is the GCF of the two terms.

--------------------------------------------------------------

Plug p = 1 and q = 2 into the factored form

10*(p+q) = 10*(1+2) = 10*(3) = 30

As a check, let's plug those p,q values into the original expression

10*p+10*q = 10*1+10*2 = 10+20 = 30

We get the same output of 30
