Answer:
1112.25
Step-by-step explanation: Step 1: Divide 1483 by 100
In this case, the number that we are "comparing" to 100 is 1483, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:
1483
100
=
1483
÷
100
=
14.83
Step 2: Multiply 14.83 by 75 to get the solution
Now that we have our normalized number, 14.83, we just have to multiply it by 75 to get our final answer. The formula for this is obviously quite simple:
14.83
×
75
=
1112.25
Basically all you got to do is at each point go left and down 6 times!
Answer: (-9,0) (-3,0) (-2,-1) (-4,-2)
Answer:
The score of the dropped grade is 6
Step-by-step explanation:
To find the average of a set of numbers you need to add all the numbers and divide by how many numbers there are. The problem wants you to solve it in reverse. Let put this into an algebraic equation with a, b, c, d, and e being the variables of the test scores
(a+b+c+d+e)/5=10
Then we can multiply both sides by 5 and get
a+b+c+d+e=50
Lets assume that c is the lowest test score. To calculate the average of that we get
a+b+d+e/4=11
Doing the same thing, we know that a+b+d+e=44
Now compare the two:
a+b+c+d+e=50
a+b+d+e=44
We can now know that c=50-44=6
So, 6 is the score of the dropped quiz. Hope that helped!
