Answer:
0
Step-by-step explanation:
I am going to simplify the top before simplifying the rest.
tan = sin/cos, so tan * cos simplifies down to sin in the numerator. which leaves sin/sin which equals 1.
to make a long story short the answer is 1
Answer:
Standard Error of the difference = 0.0695
Step-by-step explanation:
Its given that : In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport

Also, in the same district, 19 of 67 randomly selected high school juniors play a varsity sport

Now, finding the standard error of the difference :

Hence, Standard Error of the difference = 0.0695
Answer:
<u>The best prediction will be B) 35 </u>
Step-by-step explanation:
By looking at the scatterplot ,
<em>we can see that it the City MPG vs Highway MPG approximately falls on a straight line.</em>
we can either find the slope of it ( which might be a little out of syllabus ) or <em>we can extend the line connecting the maximum number of points.</em>
When we do so, We get a line as attached in the diagram.
And we extend it.
<em><u>From the graph attached we find that the value of City MPG falls somewhere in between the lines of 30 and 35</u></em><u> (</u><em><u> </u></em><u>though this is just and approximation).</u>
thus the more appropriate answer would be : 35
