Step-by-step explanation:
First exercise:
We have a right triangle with the values of each side an we have to find the following trigonometic functions (taking into account the secant function is the inverse of the cosine, the cosecant is the inverse of the sine):
1)
2)
Then:
3)
Then:
4)
Then:
Second exercise:
5) Here, we are given another right triangle and we have to find the measure of the angle .
So, according to the figure, we can use the tangent function:
Finding the value of :
Answer: Tim x(x+7)(3x-15)=04x(x+7)=2(x+7)(x-3)2 - x(x - 4) = 5
Step-by-step explanation:
Answer: The sample mean and sample standard deviation is 74.004 millimeters and 0.005 millimeters respectively.
Step-by-step explanation:
The given values : 74.001, 74.003, 74.015, 74.000, 74.005, 74.002, 74.007, and 74.000.
The sample standard deviation is given by :-
Hence, the sample mean and sample standard deviation is 74.004 millimeters and 0.005 millimeters respectively.
