Answer:

The student whose marks between quarter grades & topic tests score has  maximum proportionate deviation

Step-by-step explanation:

Percentage change shows the proportionate change in a value, from the initial point. Formula  = ( Change / Old ) x 100

Percentage change in students' quarter grades from topic tests score =

[ ( Quarter topic test score - Topic test score ) / Topic Test score ]  x 100

Eg : Quarter Grade = 80, Test score = 60.

Percentage change = [ (80 - 60)/ 60 ] x 100 = ( 20 / 60 ) x 100 = 33%

So, student who has this maximum proportionate or percentage deviation between quarter grades & topic tests score - that student change would be represented by the point farthest from 0 on a number line.

How can Ari simplify the following expression? StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1
kirill [66]

Answer:

The simplification for the expression is given as =( 7 + 2(a-3))/(a-3)

Step-by-step explanation:

To simplify the expression we will first convert the words to values in numbers and alphabets.

StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1 Over a minus 3 EndFraction

= 5/(a-3) -4/2 + 2/(a-3)

Having done that, let's move on and simplify the expression.

5/(a-3) -4/2 + 2/(a-3)

= 5/(a-3) -2+ 2/(a-3)

= 5/(a-3) + 2/(a-3) -2

= 7/(a-3) -2

=( 7 + 2(a-3))/(a-3)

50 POINTS!!!
san4es73 [151]

Step-by-step explanation:

<u>Step 1:  Determine an ordered pair</u>

A solution of an equation just means that the point lies on the line.  We can find any y-value when we plug in a specific x-value.  For example, if we want to know what ordered pair lies at x=1, we just plug in y = -1/2(1) and solve for y which gives us -1/2.  This gives us an ordered pair of (1, -1/2).  We can continue to do this for any x value.

We can also reverse the order and plug in the y-value and get the x-value in order to accomplish the same goal but it's a bit harder.

Hope this helps!
