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

Write 45 as a product of prime factors.

Marina CMI [18]

First, we determine the factors of 45. We can immediately note that 45 is the product of 9 and 5. Out of 9 and 5, 9 can further be expressed into the product of 3 and 3. The prime factorization therefore is,
45 = 3 x 3 x 5
Since the factors in the right-hand side of the equation are already prime numbers then, this factorization can no longer be written in simpler forms.
