Answer:

Students on Honor Roll had no advantage to get the Science class requested. It was a fair class assignment. In fact No Honor Roll students had advantage over honor Roll Students in obtaining Science Class as requested.  

Step-by-step explanation:

Here let us streamline the information we are given one by one

1.) Honor Roll

Get Requested Science Class                : 64

Did Not get  Requested Science Class : 80

Total                                                         : 144

Percentage of Honor Roll Students getting Science class as requested =

\frac{64}{144}

= 44.44%

2.) No Honor Roll

Get Requested Science Class               : 315

Did Not get Requested Science Class :  41

Total                                                         : 356

Percentage of Non Honor Roll Students getting Science class as requested = \frac{315}{356}

= 88.8%

By observing the above result , we can assume that Honor Roll students did not have any advantage over non Honor Roll students in getting Science Class as they requested.

7x+2y=4 <br> y=x+1<br> Solve the system of equations.<br> (1/3,4/3)<br> (2/9,11,9)<br> no solution
Lunna [17]

Answer: SECOND OPTION

Step-by-step explanation:

You can solve the system of equations by the method of substitution:

- You must susbtitute the second equation into the first equation and solve or x:

7x+2(x+1)=4\\7x+2x+2=4\\9x=4-2\\9x=2\\x=\frac{2}{9}

- Now, you must susbtitute the value of x obtained above into the second equation to calculate the value of y. Then, you have:

y=\frac{2}{9}+1\\\\y=\frac{2+9}{9}\\\\y=\frac{11}{9}

Therefore, you obtain:

(\frac{2}{9},\frac{11}{9})

tresset_1 [31]

P=s1+s2+s3

Move +s1 to the other side. Sign changes from +s1 to -s1

P-s1=s1-s1+s2+s3

p-s1=s2+s3

Move s2 to the other side. Sign changes from s2 to -s2

p-s1-s2=s2-s2+s3

p-s1-s2=s3

Answer: p-s1-s2=s3
