Step-by-step explanation:
Both are essentially same questions, considering 30 = 25 + 5.
<u>Solving c)</u>
Answer:
The student's mean score in the class is 80.6
Step-by-step explanation:
we know that
To find out the student's mean score in the class, multiply each score by its worth and adds the numbers

therefore
The student's mean score in the class is 80.6
Answer:
2
Step-by-step explanation:
f(-1)=2(-1)+2+1
f(-1)=-2+2+1
f(-1)=1
f(0)=2(0)+2+1
f(0)=0+2+1
f(0)=3
Use slope formula for the average rate of change.
(y2-y1)/(x2-x1)
(3-1)/(0+1)
(2)/(1)
2
Hope this helps!
If not, I am sorry.
So the equation is parallel and the slope will be 2
y=0.6x+b
sub in(-2,2) for x and y to find b
2=0.6(-2)+b
2+1.2=b
b=3.2
therefore the equation is y=0.6x+3.2
The arrangement should be based on the decreasing degree of the terms which may be determined by the variable x as it should come first in alphabetical order. The polynomial is then,
10x³ + 2x²y + 2xy^4 - 3y²
The degree is equal to the sum of the exponents. Thus, the answer is 5 and it is letter D.
