a store sells models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00. if the sales tax rate is 6%, what are the mean, median, mode, and range of the total cost of the cameras?

a) mean: 318 (median: 339.20) (mode: 445.20) (range: 21.20)

b) mean: 339.20 (median: 318) (mode: 445.20) (range: 243.80)

c) mean: 339.20 (median: 318) (mode: 445.20) (range: 21.20)

d) mean: 445.20 (median: 318) (mode: 339.20) (range: 243.80)

B. Mean: 339.20 (Median: 318) (Mode: 445.20) (Range: 243.80)

Step-by-step explanation:

A store sells models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00.

As a 6% tax will be levied on this as sales tax, the new prices will be, $201.40, $445.20, $286.20, $318, $445.20

Arranging them in ascending order,

201.40, 286.20, 318, 445.20, 445.20

Mean of the sample will be,

Median is the middle value of the sample. So median will be 318.

The highest number of occurrences is the mode of the set. So mode is 445.20

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
