Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 64
Sample mean = 22.3
Sample standard deviation = 8.8
We want to estimate 92% confidence interval.
92% Confidence interval:
Putting the values, we get,
Degree of freedom = n - 1 = 63
Answer:
38°
Step-by-step explanation:

Answer:
Step-by-step explanation:
hg(x) means you multiply h(x) times g(x) and then we will set it equal to .
hg(x) = which simplifies to
. Now set that equal to :
and get everything on the same side and factor:
. Factor by grouping:
and factor out what's common in each set of ( ):
which factors out to
. But factors somoe to:
(x + 1)(x - 1)(x - 1) = 0 So the solutions for this are
x = -1, 1
Answer:
70cm
Step-by-step explanation:
Answer:
Given equation of the line,
If x = 0,
Thus, the line intercepts y-axis at (0,-2)
If y = 0,
Thus, the line intercepts x-axis at (3.5,0)
By joining these two points in the graph,
We will get the graph of the given line ( shown below )
