Answer:
a) 10.6; 48.7; within
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 29.6
Standard deviation = 6.35
"According to the Empirical Rule, the ages of nearly all lead actresses will be between______________and_____________ years.
Nearly all(99.7%) will be within 3 standard deviations from the mean.
So from 29.6 - 3*6.35 = 10.6 years to 29.6 + 3*6.35 = 48.7 years.
Anna was 11-years old, so she was within this range.
So the correct answer is
a) 10.6; 48.7; within

I don't know if this is the right answer
Answer:
So in standard form equation will be 
Step-by-step explanation:
We have given expression 
Let first we solve first part of the expression
So 
Now second part 
We know the algebraic identity 
So by using this identity
Now adding first and second part
So in standard form equation will be
Answer:
What you want to do is solve for m in whichever equation it's easier to so in, then substitute that in to the other equation. For instance:
X=3m-4
Y=6-m
Solve the 2nd equation to get m=6-y
Plug that into the first equation to get x=3(6-y)-4
X=18-3y-4
X-14=-3y
14-x=3y
Y=(14-x)/3
