Step-by-step explanation:it is a linear relationship and it is changing at a constant rate
The arithmetic mean provides a single measure for a certain population, also called the average.
The sum of a set of numbers divided by the total number of numbers in the set is known as the arithmetic mean or arithmetic average in mathematics and statistics.
The ratio of the total number of observations divided by the sum of all the given observations is known as the arithmetic mean. For instance, if the data set contains 5 observations, it is possible to get the arithmetic mean by adding all 5 of the given observations and dividing by 5.

Answer:
D
Step-by-step explanation:
AC is a line, and lines are equal to 180°
BXC is 90°, as indicated
So this means that BXA has to equal 90° in total
This means the angles a and b can't be complimentary, nor supplementary
Vertical angles are angles with equal degrees, vertical to one another. so, we can cross that off.
We are left with none of the above.
Answer:
Step-by-step explanation:
Put hypotheses as:
(Two tailed test at 4%)
Since population std deviation is given we can do Z test.
Test statistic t = mean diff/se =
p value=0.075
Since p >0.04 our alpha, we accept null hypothesis.
At alphaequals0.04, we cannot reject the company's claim
