Answer:
$7,500
Step-by-step explanation:
You said it in the question.
To solve this equation, we have to isolate the variable f, or get it alone on one side of the equation.
1/7f - 5 1/2 = 9/14
To do this, we need to add 5 1/2 to both sides of the equation to 1) cancel out the - 5 1/2 on the left side of the equation, and 2) maintain equality both sides of the equation.
1/7f - 5 1/2 + 5 1/2 = 9/14 + 5 1/2
1/7f = 6 2/14
Next, we have to divide both sides by 1/7, to get rid of the coefficient of f on the left side of the equation.
1/7f ÷ 1/7 = 6 2/14 ÷ 1/7
f = 43
Therefore, the the value of f is 43.
Answer:
it is clear that at 95% confidence that the bonus plan has increased the sales significantly, because if we observe you will notice that sales after is greater than sales before in all six cases.
Step-by-step explanation:
A 95% confidence interval as we have above is the range of values that we can say with utmost certainty and confidence that 95% chance it contains the true mean of the population. in other words we can say that a 95% confidence interval defines a range of values that you can be 95% certain contains the population mean.
