You should use the Mean or avg as the central tendency. why? because you want to find the avg of the 6 scores.
89 +81+85+ 82+ 89+ 89 = 515
515/ 6 = 85.833
or 86 when rounded to the nearest whole number
Answer:
-34/3
Step-by-step explanation:
2/3(1/4x-2)=1/5(4/3x-1)
2/12x-4/3=4/15x-1/5
1/6x-4/3=4/15x-1/5
1/6x-4/15x=-1/5+4/3
-1/10x=-3/15+20/15
-1/10x=17/15
x=(17/15)/(-1/10)
x=(17/15)(-10/1)
x=-170/15
x=-34/3
Answer:
x intercepts: (-1,0) and (2.5,0)
It will be a minimum because the coeficcent for the degree is positive. The coordinates of the vertex are: (.75,-6.125)
To graph this I would first draw points on the vertex (.75,-6.125) and the x intercepts (-1,0) and (2.5,0). I would then simply just sketch a parabola that met all those points.
Step-by-step explanation:
Work Below (can clarify anything if needed)
we call n - the number
2×n + 15 = 3×n + 8
2×n - 3×n = 8 - 15
-n = -7 │ ×(-1)
n=7
