Help me pls also the answer must be a mixed number
Oksi-84 [34.3K]

Answer:

2 wholes and 5/26

Step-by-step explanation:

convert the mixed number to improper fraction

= -19/6 / -13/9

since there is 2 negatives and (-)/ (-) means your answer is positve

to divide by a fraction multiply by the reciprocal of that fraction.

19/6 x 9/13

reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.

19/2 x 3/13

multiply 19/2 x 3/13

= 57/26

= 2 wholes and 5/26

= 2.1923076

A debate team of 4 members for a high school will be chosen randomly from a potential group of 15 students. Ten of the 15 studen
iragen [17]

Answer:

A) 0.1538

Step-by-step explanation:

4 members are going to be chosen:

M1 - M2 - M3 - M4

We have to find the probability that for each member, one without experience is chosen. There is no replacents.

Initially, we have 15 students, of which 10 have none experience. So the probability that M1 is chosen as a student with no experience is \frac{10}{15}.

Then, there are 14 students, of which 9 have no experience. So the probability that M2 is chosen as a student with no experience is \frac{9}{14}.

For the third member, there are 13 students, of which 8 have no experience. So the probability that M3 is chosen as a student with no experience is \frac{8}{13}.

For the last member, there are 12 students, of which 7 have no experience. So the probability that M4 is chosen as a student with no experience is \frac{7}{12}.

What is the probability that none of the members chosen for the team have any competition experience?

This is

P = \frac{10}{15}*\frac{9}{14}*\frac{8}{13}*\frac{7}{12} = 0.1538

The correct answer is:

A) 0.1538
