y + 3 =
(x - 5)
the equation of a line in point- slope form is
y - b = m ( x - a )
where m is the slope and (a, b) a point on the line
here m =
and (a,b) = (5 , - 3 )
y + 3 =
(x - 5 ) ← in point-slope form
The margin of error of the random selection is 0.29
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:

So, we have:


The z-value for 90% confidence level is 1.645.
Substitute 1.645 for z


Take square roots

Multiply

Approximate

Hence, the margin of error is 0.29

The independent would be the base amount (0.25 in this case) The dependent would be :
the sum of the minutes x 0.25 or the entire phone bill
Ummmmmmm yeah..what is this
Let x = total games played
16% = 0.16
0.16x = 40. Divide each number by 0.16.
x = 250
