30 students.....14 are boys...that means (30 - 14) = 16 are girls

if 2 boys are dropped......14 - 2 = 12 boys
and 2 girls are added......16 + 2 = 18 girls

fraction of the class that are boys is : 12/30 which reduces to 2/5 <==

14/30 =amount of boys
(14-2)/30
12/30=new amount

16/30 =original amount of girls
(16+2)/30=new amount of girls

12/30=6/15=2/5
2/5 is your answer

Answer:

<h2>True the speed S in in Feet/second</h2>

Step-by-step explanation:

In this problem we are required to solve for the speed of an object.

given that the expression to solve for the speed is expressed as

speed= distance/time

given data

distance=100 feet

time=2.5 seconds

substituting our given data into the expression we can solve for speed as

speed (S)=100/2.5

S= 40feet/seconds

upon substituting our data the speed S was found to be 40feet/s

A video rental store keeps a list of their top 15 movie rentals each week. This week the list includes 6 action, 4 comedies, 3 d
azamat

Answer:

<h2>32/1125</h2>

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome of event/Total outcome.

If a video rental store keeps a list of their top 15 movie rentals each week, the total outcome is 15.

If the list for the week includes 6 action, 4 comedies, 3 dramas, and 2 mysteries and the store manager removes a copy of each of the 15 movies from the shelf, then randomly selects 3 of the 15 to show on the display monitors in the store, the probability that she selected 2 comedies and 1 action movie will be calculated as shown;

Probability of selecting 2 comedies  = 4/15*4/15 = 16/225 (Note that the expected outcome in this case is 4).

Probability of selecting 1 action movie = 6/15 = 2/5

<em>Hence, the probability that she selected 2 comedies and 1 action movie will be equivalent to 16/225*2/5 = 32/1125</em>

<em>Note that the rented movies will have to be returned hence reason for the replacement. </em>
