Answer:


And the slope would be:

Now we can find the means for x and y like this:


And we can find the intercept using this:

So the line would be given by:

And the best option is:
A. y = 0.894x + 0.535
Step-by-step explanation:
We have the following dataset given
x: 5,6,9,10,14
y: 4,6,9,11,12
We want to find the least-squares line appropriate for this data given by this general expresion:

Where m is the slope and b the intercept
For this case we need to calculate the slope with the following formula:

Where:


So we can find the sums like this:





With these we can find the sums:


And the slope would be:

Nowe we can find the means for x and y like this:


And we can find the intercept using this:

So the line would be given by:

And the best option is:
A. y = 0.894x + 0.535
Answer:
56 meters.
Step-by-step explanation:
Please find the attachment.
Let the leaning tower's be h meters tall, when it was originally built.
We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.
Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

Upon substituting our given values we will get,



Therefore, the leaning tower was approximately 56 meters, when it was originally built.
Answer:
<em>P=1620</em>
<em>Third option</em>
Step-by-step explanation:
<u>Horizontal Asymptotes</u>
A given function is said to have a horizontal asymptote in y=a, if:
Or,
For the given function, the population of the species of bird is given by
:
Where t is the time in years. To find the horizontal asymptote, we should compute both limits to check if they exist.
When t tends to plus infinity, P tends to 1620
.
The second asymptote is computed by:
When t tends to minus infinity, P tends to zero. Since the domain of P is
, this asymptote is not valid, thus our only asymptote is
