Answer:
A
Step-by-step explanation:
The mean is a good measure of central tendency because it takes into account all of the data compared to other. One of the instance where the mean is not good measure is when there are outliers ( extreme values) in the data in this case the median is better. In the scenario in the question the data set is nearly symmetrical therefore the mean is best central tendency measure to use
The correct answer is s = 9. Option C
Step-by-step explanation:
Given,
s³ = 729
To find the value of s.
Formula
If then, a=b
First we will factorize 729 in the power of 3.
So,
729 = 9×9×9 = 9³
Now,
s³ = 9³
Hence,
s = 9
Complete question is;
The function f(x) = (25000 + 280x)/x models the average cost per unit, f(x), for Electrostuff to manufacture x units of Electrogadget IV. How many units must the company produce to have an average cost per unit of $390?
Answer:
227 units
Step-by-step explanation:
We are given the function;
f(x) = (25000 + 280x)/x
Where;
f(x) is the average cost per unit
x is the number of units
Now, we want to find out how many units the company must produce to have an average cost per unit of $390.
Thus, plugging $390 for f(x), we have;
390 = (25000 + 280x)/x
When we cross multiply, we get;
390x = 25000 + 280x
390x - 280x = 25000
110x = 25000
x = 25000/110
x ≈ 227
A debt is a required amount a debtor owes a creditor
The best correct option is the option;
It does not represent the debt because <u>the result should be a positive number </u>since a dollar amount cannot be negative
Reason:
The given equation is presented as follows;
The given equation represents the debt because Ryan owes , and Khalil owes , while Ryan, also owes 12 dollars
However the amount Ryan owes is a positive number and not a negative number
Therefore, the correct option is <u>it does not represent the debt</u> because the result should be a positive number since a dollar amount cannot be negative
