Question

I NEED HELP:


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? HELP

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)

Answer 1

Answer:

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,

$\overline{x}=\dfrac{201.40+286.20+318+445.20+445.20}{5}=\dfrac{1696}{5}=339.20$

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

Answer 2

Answer:

( LESSON 5 Measures of Central Tendency and Dispersion )

1 ) Find the mean, median, and mode of the data set. Round to the nearest tenth.  15,139,9,7,1,11,10,13,1,13

C ) mean= 9.3  ,median= 10  ,mode= 13

2 ) Find the mean, median, and mode of the data set. Round to the nearest tenth.  test scores on a math exam:

88, 89, 65, 62, 83, 63, 84, 63, 74, 64, 71, 82, 66, 88, 79, 60, 86, 63, 93, 99, 60, 85

B) mean=75.8 ,median=76.5 ,mode=63

3 ) The table shows the number of hours that a grouped of students spent studying for the SAT.......

B ) Mean-18.3   Median- 19   Mode- 14   Range-9

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

B ) mean = $339.20   median =$318.00   mode = $445.20   range=$243.80
