Answer:
-6x^2+21x+18
Step-by-step explanation:
Answer:
Table1
-1 undefined since we cannot take the sqrt of a negative number
0 0
1 -1
4 -2
Step-by-step explanation:
f(x) = sqrt(x)
A reflection over the x axis is-f(x)
g(x) = -sqrt(x)
x -sqrt(x)
-1 undefined since we cannot take the sqrt of a negative number
0 0
1 -1
4 -2
Remember that percent means parts out of 100
x/100
discount is the decrease
so we divide the decrease by the original total and get
100/5775=0.0173
convert to fraction
0.0173/1
make bottom number 100
multiply by 100/100
1.73/100=1.73%
round
2%

Z = (X-Mean)/SD
<span>z1 = (580-600)/20 = - 1 </span>
<span>z2 = (620-600)/20 = + 1 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean +/- 1*SD covers 68% of the values </span>
<span>Therefore, required percent is 68%
hopes this help :) :D :)</span>
