Answer:
number of people / land area = population density
57,714 / 836,109 ≈ 0.07 people/[tex]mi^2[/tex]
Answer:
.07 people per square mile
Step-by-step explanation:
We can just divide the people by area
57714/836109=.06902688525 or about .07 people per square mile
I think you got confused about the division and what to divide by what
Look over here we divide the PEOPLE by the AREA so we get the amount of PEOPLE per square mile
If we did it the opposite way we get THE AREA that EACH PERSON HAS

You used 15.6 kWh to recharge an EV at a cost of 11.6 cents per kWh. How
much did you spend to recharge the car?
$180.96
$18.00
$1.36
$1.81
Answer:
1.81
Step-by-step explanation:
the reason is because many may think by using a calculator, and make a mistake by putting 15.6 x 11.6, and think "Oh its 180.96" but they forget that they are multiplying cents, but with money you round the nearest decimal to a cent, so they get 1.81
15.6 x 11.6 = 180.96
flip it and jump the 1 a single spot to the left. (1 80.96)
Now jump the decimal between the 1, and the 8. (1.8096)
Now round the thousandth and ten thousandth to remove the zero and make it one. (1.8096= 1.81)
And that's how you get 1.81

You wonder what is the average number of credits Le Moyne students take per semester. You speak with the Le Moyne registrar, and they tell you that Le Moyne students take an average of 17 credits per semester with a population standard deviation of 2.5 credits. We plan to take a sample of 49 students and ask each student how many credits they plan to take. Assume that the population mean is 17 credits and the populations standard deviation is 2.5 credits. What does the CLT say about the distribution of the sample mean of 49 students
Answer:
The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Assume that the population mean is 17 credits and the populations standard deviation is 2.5 credits.
This means that [tex]\mu = 17, \sigma = 2.5[/tex]
What does the CLT say about the distribution of the sample mean of 49 students?
It is approximately normal.
The mean is 17.
Due to the sample of 49, n = 49, and the standard deviation is [tex]s = \frac{2.5}{\sqrt{49}} = 0.3571[/tex]
The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.

Answer:
B) f = (6 x 8) + 4
Step-by-step explanation:
Remember this: 1 cup = 8 fl oz
They're asking for the total number of fluid ounces of detergent, and we're given 6 cups and 4 fl oz.
Set up a proportion to find the total number of fl oz from the 6 cups, let variable x be the total oz of the 6 cups:
[tex]\frac{1 cup}{8 oz} = \frac{6 cups}{x oz}[/tex]
The answer should be 48 fl oz, then you add the 4 fl oz to have the total of 52 fl oz.

can someone find the length of the spine plss
Answer:
48.2 cm
Step-by-step explanation:
The bottom side of the large triangle has length 78 cm.
The bottom side of the right triangle has length 78 cm/2 = 39 cm.
Now we use the Pythagorean theorem to find the vertical side, the spine.
39² + s² = 62²
s² = 3844 - 1521
s² = 2323
s = 48.2
Answer: 48.2 cm
The amount of interest accrued on
a $7,000 loan with 6% interest after t years.
Answer:
$420t
Step-by-step explanation:
Given data
Principal= $7000
Rate= 6%
Time= t years
The expression for the amount is
Simple interest= PRT/100
Sustitute
Simple interest= 7000*6*t/100
Simple interest= 42000t/100
Simple interest= 420t
Hence the amount after t years is $420t

What is the area of the obtuse triangle given below?
2 9
Answer:
The area is 9 unit squared
Step-by-step explanation:
Given
The right parameters are:
[tex]Base = 2[/tex]
[tex]Height = 9[/tex]
Required
The area of the triangle
This is calculated as:
[tex]Area = 0.5 * Base * Height[/tex]
So, we have:
[tex]Area = 0.5 * 2 * 9[/tex]
[tex]Area = 9[/tex]
Hence, the area is 9 unit squared
Consider the function g(x) = StartLayout Enlarged left-brace first row negative 9, x less-than 11 second row 7, x greater-than-or-equal-to 11 EndLayout.
What is Limit of g (x) as x approaches 11, if it exists?
–9
–1
7
DNE
The limit as g(x) approaches 11 doesn't exist.
[tex]\lim_{x \to 11} g(x) = DNE[/tex]
It looks like you are working with the following piecewise defined function:
[tex]g(x)=\left \{ {{-9;x<11} \atop {7;x\geq11}} \right.[/tex]
There is a rule in calculus that tells us that for a limit to exist, both lateral limits must be the same as x approaches a given value. This is:
[tex]\lim_{x \to a^{-}} f(x)=\lim_{x \to a^{+}} f(x)[/tex]
if and only if this is true, then:
[tex]\lim_{x \to a^{-}} f(x)=\lim_{x \to a^{+}} f(x)=\lim_{x \to a} f(x)[/tex]
if that condition isn't met, then the limit doesn't exist.
So let's calculate the lateral limits for this function:
[tex]\lim_{x \to 11^{-}} g(x) = -9[/tex]
This means that as x approaches 11 from the left, the function will return a value close to -9
Now, let's calculate the lateral limits for this function:
[tex]\lim_{x \to 11^{+}} g(x) = 7[/tex]
This means that as x approaches 11 from the right, the function will return a value close to 7
You can better visualize this in the graph of the function which I attached to this answer.
Notice that both lateral limits are different, from the left you got a -9 and from the right you got a 7. Therefore, according to the rule I wrote above, the limit does not exist.
