5) Rolanda scored 20, 15and 16 on hefirst three mathquizzes. Jetta scored 16, 19and17 on her quizzes Usingthe mean to compare, whohas the higher math quizscores so far?
Answers
The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52
Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)
51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)
Mean: The mean is the average of the numbers; a calculated (central) value of a set of numbers.
How to find it? We add all of the scores together and then divide them by the number of scores.
They gave us the numbers 20, 15, and 16
1st. Lets add
20 + 15 + 16 = 51
2nd. Divide by 3 since their are 3 test scores
51 ÷ 3 = 17
So rolanda's mean is 17!

So jetta's mean is 17.333333333333333
Now lets compare:)
Rolanda's mean = 17
Jetta's mean = 17.33333333333333333
Obviously, whos is bigger?
Jetta's Mean is bigger :)
Hope this helps!

how do you solve for x?
1) write the equation
y=5x-8
2) substitute 12 for y
12=5x-8
3) Add 8 to each side
20=5x
4) divide each side by 5
x=4

the choices:
0 solutions: means the lines don't intercect at all, meaning same slope but different y intercept or they ar paralell
1 solution: lines intercect in 1 point
2 solutions: curvy line with a straight line thorugh middle
infinetly solutions: same line
to find slope you do
slope=(y1-y2)/(x1-x2)
first line is
(2,-7)
(0,6)
(x,y)
x1=2
y1=-7
x2=0
y2=6
subsitute
(-7-6)/(2-0)=-13/2
slope=-13/2
subsitute
y=-13/2x+b
subsitute one of the points
(0,6)
x=0
y=6
6=-13/2(0)+b
6=0+b
6=b
y=-13/2+6
now solve for the other equation
(3,0)
(0,-3)
x1=3
y1=0
x2=0
y2=-3
subsitute
(0-(-3))/(3-0)=(0+3)/(3)=3/3=1
y=1x+b
subsitute
(3,0)
x=3
y=0
0=1(3)+b
0=3+b
subtract 3
-3=b
y=x-3
we have the lines
y=-13/2x-6 and
y=x-3
solve for a common solution
y=x-3 and y=-13/2x-6 therefor
x-3=-13/2x-6
add 6 to both sides
x+3=-13/2x
multiply both sides by -2
-2x-6=13x
add 2x to both sides
-6=15x
divide both sides by 15
-2/5=x
subsitute
y=x-3
y=-2/5-3
y=-3 and 2/5 or -17/5
the solution is (-2/5, -17/5)
there is only one solution
the answer is B

Written in y=mx+b form: m is the slope and b is the y-intercept.First you need to use the two points to find the slope, the formula is .
So now to find the y-intercept, You can use either or of the (x,y) points since the answer will be the same, but for this I'm going to use (5,2).
Now that we have the slope and the y-intercept, we can put it together to make the equation .
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
