Answer:
0.43
Step-by-step explanation:
2+3+1+1=7
7*4+28==Area of full shape
(2*4)+(1*4)=12==Area of shaded shapes
12/28=0.428571>rounded up>0.43

Hello!
The solution is where the lines intersect. As you can see, they only intersect at one point.
A) It as one solution.
To find our solution, we just see what the point is they intersect at.As you can see, they intersect at (4,4).
B) (4,4)
I hope this helps!
There would be $13410 because 4500 x 0.22 x 9 = 8910
4500 + 8910 = 13410
Answer:
Its standard deviation is 3.79.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
So
Its standard deviation is 3.79.
