Answer:
3
Step-by-step explanation:
To evaluate the expression, we have to substitute the variable in the expression, z, for its stated value. Given that z = 6, substitute 6 for the z in the expression and solve:
Thus, the answer is 3.
Answer:
The 95% confidence interval is
The pivot function used is
Step-by-step explanation:
From the question we are told that
The data given is 246 242 248 245 250 244 252 248 248 247 250 248 246 242 248 244 245 246 250 242
The sample size is
Given that the confidence level is 95% then the level of significance is

The pivot function used is
The equation of the midline of the sinusoidal function is y =0.
We have to determine
What is the equation of the midline of the sinusoidal function?
<h3>The midline of the sinusoidal function;</h3>The mid-line of any Sinusoidal function is a line that goes between the highest and lowest values of y of that function.
Here we will take the middle value of y.
The formula is used to find midline is;
In the given graph, the Highest value of the function is 5 and the Lowest value of the function is -5.
Substitute all the values in the formula;
Hence, The equation of the midline of the sinusoidal function is y =0.
