It would be helpful if you draw the situation in the problem. We will see that a right triangle is made from the system. By using knowledge on trigonometric functions, we can calculate for the height of the roller coaster. We do as follows:
tan (65) = height / 130
height = 278.79 ft
Hope this answers the question.
The expected frequency of east campus and passed is C. 42 students
<h3>How to calculate the value?</h3>
The table for expected frequency is ,
East Campus West Campus Total
Passed (84*100)/22=42 (84*100)/200 =42 84
Failed (116*100)/200=58 (116*100)/22=58 116
Total 100 100 200
Passed = 84×100/200
= 42
Therefore, the expected frequency of East Campus and Passed is 42 students.

Step-by-step explanation:
Answer:
For a=0.9876 and b=0.9887 mid point will be 0.98815
Step-by-step explanation:
We have given a = 0.9876 and b = 0.9887
And N = 2
We have to find the mid point
For finding mid point we know that formula
Midpoint , here we have given a=0.9876 and b = 0.9887
So midpoint will be
So for a=0.9876 and b=0.9887 mid point will be 0.98815
