Answer:
4
Step-by-step explanation:
Hey there! Hello!
For this problem, you first need to figure out how many questions Nicholas got right, got wrong, and didn't answer. Then, you need to compare these to how many points he gets for each one. To do the first thing I mentioned, you need to add together how many problems your question accounts for, then subtract these from 100 and assume that these are questions he got wrong.
So, he has a total of 86 problems correct (times 1 will be 86 points added to his total score), 6 problems unanswered (times 0 will be 0 points that won't affect his score), and 8 problems incorrect (times –1/4, or –0.25, will be 2 points taken away from his total score).
Then, plug them into an equation. Since the unanswered questions don't count for anything, they can be omitted.
Your final answer will be C.
Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
Answer with explanation:
Table Wrote By Mika:
x : 0 3 6
y : 2 5 8
→Ratio of difference of y values to x values between two points,when represented on two dimensional plane
Since,slope is same, so it is linear relationship.
If we represent these points on a line ,and get a straight line,it means the function is linear ,and if this line passes through point (0,0),then the relationship will be proportional.
Equation of line passing through two points can be obtained by the formula
→y-b=m(x-a)
→y-2=1×(x-0)
→y=x+2, is equation of linear function.
Checking whether the line passes through (0,0) or not
LHS, at ,(0,0)=0
RHS at (0,0)=0+2=2
LHS≠RHS
So,the given points when combined forms a linear function, does not have proportional relationship.
→If the linear function has the type : y= k x, then there would have been proportional relationship means ratio of y values to x values of each point given, is same.
