When you plot the points and use the vertical line test, you'll see that none of the vertical lines go through two points. Therefore verifying that this set of points represents a function.
Answer:The center is (-5,2)
The radius is 5
Step-by-step explanation:
Equation of a circle is:
(x-h)^2+(y-k)^2=r^2
(x+5)^2+(y-2)^2=5^2
Comparing both equations we get :
The center (-5,2)
The radius is 5
Answer:
And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence
Step-by-step explanation:
Information given
represent the sample mean
population mean
s= 5.2 represent the sample standard deviation
n=59 represent the sample size
Confidence interval
The confidence interval for the true mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence interval is 0.90 or 90%, the significance is
and
, and the critical value is
Now we have everything in order to replace into formula (1):
And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence
The answer is one and five eighths.
Answer:When you multiply a negative number to a positive number, your answer is a negative number. It doesn't matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.
