Select the correct answer. Twenty students in Class A and 20 students in Class B were asked how many hours they took to prepare
Lunna [17]

Answer:

B: The mean study time of students in Class B is less than students in Class A.

Step-by-step explanation:

To find out why answer B is the right answer, I will give you facts from each option.

Option A is false. <em>The mean study time in Class A is 4.8. Meanwhile in Class B it is 4. For Class A, sum up the 20 study times which is 96 and divide them by 20, you will get 4.8 hours of mean study time. For Class B, the sum of the 20 study times is 80, which divided by 20 will be 4. </em>

Option B is True. <em>See previous explanation. </em>

Option C is False. <em>The median study time in Class B is 4. The median study time in Class A is 4.8, </em>

Option D is False. <em>The range in Class A is from 2 to 8. The range in Class B is from 2 to 7. </em>

Option E is False: <em>The mean and median study time of these classes is different.</em>

One month Ashley rented 2 movies and 5 video games for a total of $33. The next month she rented 8 movies and 3 video games for
Ray Of Light [21]

To answer this question, you should set up and equation before doing anything else. So for this question you 're going to set up two equations.

The first equation is 2x+5y=33

The second equation is 8x+3y=30

Once you do that you have to solve for either X or Y by canceling out the other one. In this problem figuring out the Y is easier because you can cancel the X's more easily than the Y. To cancel a variable, they have to add up to 0.

So to cancel the X you multiply the equation 2x+5y=33 by -4.

That gives you -8x-20y= -132

Then you set up the two equations and add them together.

(-8x-20y= -132) + (8x+3y=30)

That gives you -17y = -102

So then you solve for Y by dividing by -17. You find out that Y is equal to 6. Then you plug the 6 back into the ORIGINAL equations and solve for X, which turns out to be 1.5

Hope this helped and if you get confused or have questions please ask :)
