Ineed :

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

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
