Answer:
see attached for sketch of Empirical Rule
Step-by-step explanation:
The Empirical Rule (also known is the "68-95-99.7" rule) states that nearly all of the data will fall within three standard deviations of the mean.
3(4x+3)=12x+9
i don't know what do you need,
if roots, let 12x+9=0
the root is x=-3/4
If the origin is not shaded the answer is C
Your answer is
B) 1/2
because there are 5 odd and 5 even numbers from 5 through 10, so it would be 1/2.
Glad I could help, and good luck!
