Mary’s grade on her research paper counts for 20% of her final grade in english. if there are a total of 400 points possible how many points can she earn for her research paper

80 points

Step-by-step explanation:

Total percentage is always 100%

Total points is 400

The research paper has a weight of 20% of the total (which is 400 points).

The highest possible points is 20% of 400

First, we need to convert percentage to decimal by dividing by 100. Then we will multiply that decimal with 400. Shown below:

20% = 20/100 = 0.2

Now,

0.2 * 400 = 80 points

So, she can earn 80 points for her research paper

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
