The equation representing Max's number is 
.
<h3>What is an equation?</h3>
In its simplest form in algebra, the definition of an equation may be a mathematical statement that shows that two mathematical expressions are equal. It consists of variables dependent and independent variables. They can be linear or non-linear in nature.
Let the number Max is thinking be 'x'
He adds 8 to the number and then he doubles the sum.
Sum means we are adding a number to x, in this case it is 8.
Double the number means twice the given number in this case it is twice the sum of number with 8.
As per the statement:
The expression to represents Max's number
=

Answer:
B) A one-sample t-test for population mean would be used.
Step-by-step explanation:
The complete question is shown in the image below.
The marketing executive is interested in comparing the mean number of sales of this year to that of previous year.
The marketing executive already has the value of mean from previous year and uses a sample to calculate the mean and standard deviation of sales for the current year.
Since, data is being collected for one sample only this limits us to chose between one sample test for mean. So now the possible options are one sample t-test for population mean and one sample t-test for population mean.
If we read the statement we can see that we have the value of sample mean and sample standard deviation. Value of population standard deviation is unknown. In cases where value of population standard deviation is not known and sample standard deviation is given, t-test is used.
Therefore, we can conclude that A one-sample t-test for population mean would be used.
Is the question what c is?
if so just subtract 3 from 10
3-10 = -7
therefore c = -7
hope that helps :)
