If a student is selected at random find the probability the student is a senior given that it's a female round to the nearest whole percent

Answers

Answer:

16%

Step-by-step explanation:

It says to find the probability the student is a senior given that it's a Female. So let's see. There are 19 females in total, and we're trying to figure out the probability that one of them will be a senior. Well, there are 3 female seniors.

[tex]\frac{3}{19\\}[/tex]

Divide 3 by 19 (not 19÷3, 3÷19)

=.157894736etc

You'll get a continuous decimal, but that's ok. The directions say round to the nearest whole percent. That means the percent should end up with no decimals.

16% (not 15.7, round it up instead to 16%)

Therefore, the answer is 16%. Hope this helps! :)

The probability of the student is a senior and female is 16%

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

It says to find the probability the student is a senior given that it's a Female. There are 19 females in total, and we're trying to figure out the probability that one of them will be a senior. Well, there are 3 female seniors.

The probability of the student being a senior and female is calculated  as below:-

Divide 3 by 19 (not 19÷3, 3÷19)

Probability = 0.157894736 = 0.16

Probability = 0.16  x 100 = 16%

Therefore, the probability of the student is a senior and female is 16%

Multiply each side by 6 to get rid of the fractions

6*2/3 ( 1+n) =6* -1/2 n

4(1+n) = -3n

Distribute

4+4n = -3n

Subtract 4n from each side

4+4n -4n = -3n -4n

25. Leena and Ricky went for jogging in the morning. Leena ran 2/3 of the track and Ricky ran 5/6 of
the same track. Who ran more and by how much?

Answers

Answer:

Ricky ran 16.66% more of the track than Leena

Step-by-step explanation:

First, we find how much each ran as a percentage.

Leena ran 2/3 of the track

As a percentage, Leena ran:

2*100%/3 = 66.67%.

Ricky ran 5/6 of the same track.

As a percentage, Ricky ran:

5*100%/6 = 8333%

Thus Rick ran more, by 83.33% - 66.67% = 16.66%.

Can anyone tell me what the answer to this problem is and the explination?

Answers

The figure shown above is triangle. The area of the triangle is a= 1/2base times height.

Base  is 10 .  The height is 6.

A= 1/2bh

A= 1/2*10*6

A= 1/2*60

A= 30

Or you can find the area of the triangle separately and add them up.

First triangle :

The half of the base is 10/2= 5

B= 5  H= 6

A= 1/2*6*5

A=  15

Second triangle :

b= 5

h= 6

a= 1/2*5*6

a= 15

Add up them both areas 15+15= 30

         

In southern California, a growing number of individuals pursuing teaching credentials are choosing paid internships over traditional student teaching programs. A group of eleven candidates for five local teaching positions consisted of six who had enrolled in paid internships and five who enrolled in traditional student teaching programs. All eleven candidates appear to be equally qualified, so five are randomly selected to fill the open positions. Let Y be the number of internship trained candidates who are hired. (a) Does Y have a binomial or hypergeometric distribution

Answers

Answer:

Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.

Step-by-step explanation:

Difference between hypergeometric and binomial distributions:

In the hypergeometric distribution, trials are dependent of other trials, while in the binomial distribution, they are independent. This can be examplified that in the hypergeometric distribution, the candidates are chosen from a set without replacement, while in the binomial distribution they are chosen with replacement.

In this question:
