Answer:
Hi i think that the correct answer is B
Answer:
And we can find this probability with this difference:
If we use the normal standard table or excel we got:
And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %
Step-by-step explanation:
Let X the random variable that represent the birth weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And we can use the z score formula given byÑ
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
If we use the normal standard table or excel we got:
And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %
Answer:

Step-by-step explanation:
Given
The attached graph
Required
Determine the range of the graph
First, we list out the coordinate of each point on the graph:
The points are:

A function has the form: (x,y)
Where
y = range:
From the coordinate points above,

Order from least to greatest"

Hence, the range are: 
Answer:
Yes, because when the values are substituted in, the equation becomes a true statement
Step-by-step explanation:
plug in the values for x and y and see if the equation makes sense
x=3
y=11
1/3(3)+11=12
1+11=12
12=12
Since the above equation is true, the point is a solution for the linear equation.
