A logarithmic function without a subscript means that it must be log base 10.
When learning about logarithms, a textbook/teacher provides their students with the following general equations
Hopefully you are familiar with this. Using the equations that I just showed, we can change the equation to
This would make answer choice C correct.
Answer: (-1,7)
if a plane is reflected across the y-axis, it’s being reflected horizontally. S (1,7) from the first quadrant is being reflecting across the y axis into the second quadrant, where we have both negative and positive points.
Yes indeed Yes indeed Yes indeed
Answer:
There is not enough evidence to support the claim that the true average penetration is at most 50 mils.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 50
Sample mean, = 52.8
Sample size, n = 45
Alpha, α = 0.05
Sample standard deviation, s = 4.5
First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
The calculated test statistic is greater than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Conclusion:
There is not enough evidence to support the claim that the true average penetration is at most 50 mils.
