Remember that if an x=value makes a denominator 0, the entire equation is undefined.
So whenever x = -3/2 or x = 0 the equation is undefined, and that means that
x cannot be -3/2 or 0.
4/5 is in its simplest form.
Answer:
In the time(x) column add 3 every time (start with 3 in first column). For the steps (y) add 126 every time (start with 126 in first column.
Step-by-step explanation:
Answer:
slope
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Since m is the coefficient of the x- term, then
The coefficient of the x- term gives the slope
Answer:
The critical value can be founded in the normal standard distribution table using the value of 
and we got 
. Replacing the info given we got:
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the sample mean
represent the sample size
And we want to find the margin of error for a confidence level of 95%. So then the significance level would be 
and . The margin of error is given by:
The critical value can be founded in the normal standard distribution table using the value of and we got . Replacing the info given we got:
