Answer:
=2 7/12 is needed on sunday
Step-by-step explanation:
Friday + Saturday + Sunday = total time studying
1 1/4 + 2 2/3 + sunday = 6 1/2
Get a common denominator of 12
1/4*3/3 =3/12
2/3 *4/4 =8/12
1/2 *6/6=6/12
1 3/12 + 2 8/12 + sunday = 6 6/12
Combine terms
3 11/12 + sunday = 6 6/12
Subtract 3 11/12 from each side
3 11/12 - 3 11/12 + sunday = 6 6/12 - 3 11/12
sunday = 6 6/12 - 3 11/12
Borrow 1 from 6 in the form of 12/12
sunday = 5 + 12/12+ 6/12 - 3 11/12
= 5 18/12 - 3 11/12
=2 7/12

Hello!</h2>
The answer is:
The x-coordinate of the solution to the system of equations is:

<h2>
Why?</h2>
We can solve the problem writing both equations as a system of equations.
So, we are given the equations:

Then, solving by reduction we have:
Multiplying the first equation by 2 in order to reduce the variable "x", we have:


Now, substituting "y" into the first equation, to isolate "x" we have:

Hence we have that the x-coordinate of the solution to the system of equations is

Have a nice day!

Step-by-step explanation:
Selected theme park admission prices has the lower standard deviation.
Specific home stereo system's distribution is more spread out since the ratio between the standard deviation and the mean is greater compared to that of selected theme park admission prices.
specific home stereo system: 3.99/59=0.0676.
selected theme park admission prices: 4/1499=0.002668
0.0676>0.002668
12/3=4
so m=4
6x4=24
6x1=6
24-6=18
