3. The cost of hotel rooms at Stay in
Comfort range from $49 to $229 per
night. Here are the rates charged, in
dollars, for one particular night:
70, 75, 85, 65, 75, 90, 70, 75, 60, 80, 95,
85, 75, 20, 65, 229

a) Calculate the mean, median,
and mode costs.

b) Identify the outliers.
How can you explain these costs?

c) Calculate the mean, median, and
mode costs without the outliers.
How is each average affected
when the outliers are not
included?

d) Should the outliers be used
when reporting the average cost
of a hotel room? Explain.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

answer: do we write it

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
