Answer:
This proves that f is continous at x=5.
Step-by-step explanation:
Taking f(x) = 3x-1 and , we want to find a such that
At first, we will assume that this delta exists and we will try to figure out its value.
Suppose that . Then
.
Then, if , then . So, in this case, if we get that . The maximum value of delta is .
By definition, this procedure proves that . Note that f(5)=14, so this proves that f is continous at x=5.
<u>3</u> x 4 = <u>12</u><u>
</u>5 x 4 = <u />20
Since 5 times 4 is 20, then you must also multiply 3 by 4 because what you do to one part of the fraction you must do to the other.<u>

Answer: This means that the salaries of their marketing professionals are not closely related to their job titles. In further explanation, this shows that a professional with a higher job title, may be paid a lower salary when compared to a professional with a lower job title.
A 0.85 R-Squared shows that the points are far from the trend lines. From this, we can assume that the marketing professionals are paid base on commission on sales, and not base on job position.
Step-by-step explanation: R-Squared is a measure used in statistics, to represent how much proportion of the dependent variables that is explained by the independent variables. A high value of R^2 shows a very low correlation between the dependent and independent variables, while a low value of R^2 shows that the dependent and independent variables are closely related. The R-Squared value are a measure of percentage value.
