Answer:
Correct choice: D.
Step-by-step explanation:
The point-slope form of the equation of a line is:
Where m is the slope and (h,k) is a point through which the line passes.
According to the question, the slope of a line is m=4 and it contains the point (-3,-4), thus, replacing the values:
Operating:
Correct choice: D.
Answer:
Value is 1.
Step-by-step explanation:
To find the value of
is always equal to 1, but if zero to the power 0 is not defined.
Or simply we say that:
is always equal to 1
Here,
A non-zero number = 30 ≠0
then;
by definition:
Therefore, the value of is 1
Answer:

Step-by-step explanation:
Answer:
Option B is correct.
Use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.
Step-by-step Explanation:
The clear, complete table For this question is presented in the attached image to this solution.
It should be noted that For this question, the running coach wants to test if participating in weekly running clubs significantly improves the time to run a mile.
In the data setup, the mean time to run a mile in January for those that participate in weekly running clubs and those that do not was provided.
The mean time to run a mile in June too is provided for those that participate in weekly running clubs and those that do not.
Then the difference in the mean time to run a mile in January and June for the two classes (those that participate in weekly running clubs and those that do not) is also provided.
Since, the aim of the running coach is to test if participating in weekly running clubs significantly improves the time to run a mile, so, it is logical that it is the improvements in running times for the two groups that should be compared.
Hence, we should use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.
Hope this Helps!!!
Answer:
Area of circle = 201.09 ft²
Step-by-step explanation:
Given the following data;
Radius, r = 8 ft
To find the area of the circular area;
Area of circle = πr²
Area of circle = 3.142 * 8²
Area of circle = 3.142 * 64
Area of circle = 201.09 ft²
Therefore, the measurement which is closest to the area is 201.09 square feet.
