In an ecological study, the sampling mean proportion is 0.28 and the sample size is 50. a) What is the margin of error with a confidence level of 95%?
The solution to a system of two linear equations is (4, -3). One equation has a slope of 4. The slope of the other line is the negative reciprocal of the slope of the first. The system described above is represented by the following equations: y --X-2 y - 4x - 19 Please select the best answer from the choices provided
Answer:
cot x and sec x
Step-by-step explanation:
Given are 4 trignometric functions defined in the interval [0,\pi]
We are asked to identity the functions which can take values more than 1.
We have
have values always between -1 and 1 for any value of x
Hence sinx and cosx cannot take values greater than 1.
This value being ratio of cos to sin will become greater than 1 whenever cos >sin value.
SO this function can take values >1
This function being reciprocal of cos function always can take values outside
(-1,1)
Hence this value can be greater than 1
What u have to do is find the absolute value and since it is in different quadrants you subtract so it would be 3 the expression would be |-6|-|3|=X
