Answer:
The value is 
Step-by-step explanation:
From the question we are told to obtain the area to the of the z-score 1.39 and to the left of the z-score 1.53, this is mathematically represented as
From the z table on the question the area under the normal curve to the left corresponding to 1.53 and 1.39 is
and
So
=>
Y=18-12x
I believe this is it
Answer:
In order to answer this you would need to use this equation: <em>A = πr² </em> (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is <em>A = πr² </em>
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for <em>A = πr² .</em>
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :<em>A = π10.35² </em>
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n
Do the right first. It's the one that you have to pay the most attention to because it is any intuative. y = 1/(x - 7) That looks like it should shift to the left. But it does not. Take a simple example
if y = 1/x is used first then if x = 1 then y = 1/1 = 1
if y = 1/(x - 7) is considered then if x = 1 then y = 1/(1 - 7) = -1/6
The question is where does 1/x = -1/6 the answer is when x = -6
So the same answer is obtained with a shift to the right. Try this a couple of times to convince yourself of it.
To shift the graph up, all you need do is add 12.
y = 1/(x - 7) + 12 is your answer. I'll put a graph up to show you how it works.
Notice the blue function. It is shifted up 12 (which you can see from the portion that starts from the left and eventually heads down. And then it is also going right (same part of the blue graph.
The red graph is y = 1/x
It should be D. Because the equation is 2(width+ height + length
