Mode = is the number with the highest frequency so the answer is 4.
Mean = the average so the answer is 3+4+5+4+6+4+7=33 so 33/7=4.7 (rounded to the nearest one decimal).
Median = the middle number, so the answer is 4.

The cost of a laptop computer in 2007 was $1,250. In 2009, the price decreased to $1,100.

sashaice [31]

Given : The Cost of Laptop in 2007 is $1250

Given : The Cost of Laptop in 2009 is $1100

Decrease in Price of Laptop from 2007 to 2009 : (1250 - 1100) = $150

A) Percent Decrease in the Price of the Laptop from 2007 to 2009 is :

$\mathsf{\implies \frac{Decrease\;in\;Price\;of\;Laptop\;from\;2007\;to\;2009}{Price\;of\;Laptop\;in\;2007} \times 100}$

$\mathsf{\implies \frac{150}{1250} \times 100}$

$\mathsf{\implies 12\%}$

Given : Decrease in Price of Laptop from 2009 to 2010 = $165

B) Percent Decrease in the Price of the Laptop from 2009 to 2010 is :

$\mathsf{\implies \frac{Decrease\;in\;Price\;of\;Laptop\;from\;2009\;to\;2010}{Price\;of\;Laptop\;in\;2009} \times 100}$

$\mathsf{\implies \frac{165}{1100} \times 100}$

$\mathsf{\implies 15\%}$

The cost of a phone has increased by 10% to £352 work out the original price

lions [1.4K]

The answer is £316.80.

This is because you're working out the original price from a percentage increase.

To do this, you do the original price ÷ (1- percentage increase as a decimal).

So it would be 352 ÷ (1 - 0.10) which is 352 ÷ 0.9.

And that equals to £316.80.
