What is the slope of the line represented by the equation y = - 글 x + 끝?
1 answer:
Given:
Consider the given equation is:
To find:
The slope of the line that is represented by the given equation.
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get
Therefore, the slope of the given equation is .

Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
