I believe that $10.80 is the answer :) hope this helps
Equation for linear relationship is y=mx+b, where m is slope (rate of change), and b is y-intercept. Y-intercept is where you start of at. Like if I had 20 dollars and started earning 5 dollars each day, my y-intercept would be 20 dollars.
Your rate of change is $5 dollars PER HOUR, and y-intercept is $15 dollars. this is because it is a flat fee. She could walkyour dog for 5 minutes but she still charges 15 dollars.
y=5x+15
Answer:
As confidence level decreases, the interval width decreases too.
Step-by-step explanation:
The confidence interval is an interval in which is probable that the true value of an unknown variable is contained. The confidence level is the probability that this true value is within the limits of the interval.
The degree of confidence or confidence level is defined and affects the width of the confidence interval.
If the true value of the mean foot length is within 21.71 and 25.09 with a 95% confidence level, if we decrease the confidence level to 90%, we expect to have an interval with smaller width.
When we increase the confidence level, we expect to be more sure about the true value being contained in the interval. As we do not count with new information, the only way to be more sure is to have a wider interval.
If the confidence level decreases, we can have a narrower confidence interval as we are not so severe with the probability of containing the true level.
For the number line, an open circle will be drawn on the value of 6 and the arrow pointing to the right side.
<h3>Number line and inequality</h3>
Given the inequality expression as shown
-2x + 9 < x − 9
Collect the like terms
-2x - x < -9 - 9
-3x < -18
Divide through by -3
x > -18/-3
x > 6
