MEAN:
(12 + 16 + 10 + 9 + 20 + 11 + 20) / 7 = 14
RANGE:
Highest value: 20
Lowest value: 9
Range: 20 - 9 = 11
INTERQUARTILE RANGE:
First quartile: 16 (It is between 12 and 10)
Third quartile: 11 (It is between 20 and 20)
Interquartile range: 16 - 11 = 5

Answer:
d. -3a3 – 3a² + a +8
Step-by-step explanation:
Simplify the expression.
There are 540 fuses in total and the original price of the internet is $55.91
<h3>
How to work with percentages?</h3>
a) We know that 5% of the fuses are faulty, and there are 27 faulty fusses, then we can write:
5% = 27
100% = x
We want to find x, to do that, we can write:
x = 27*(100%/5%) = 27*20 = 540
There are 540 fuses in total.
b) Now we know that the original price is P, and when we decrease it by 7%, then new price is $52.00
Then we can write:
$52.00 = P*(1 - 7%/100%)
$52.00 = P*(0.93)
$52.00/0.93 = P = $55.91
The original price is $55.91
