Isn't that simply asking you to compute 30% of 20?
30 x
----- = ------
100 20
100x = 600
x = 6
So, out of those 20 numbers, you would expect that 6 of them would begin with the digit 1.
The correct answer is a) $382.50.
He works 3 events and averages 150 pretzels; this is 3(150) = 450 pretzels. Since his cost is $0.85 each, we have
450(0.85) = 382.50
Answer:the median is 20 and the lower quartile is 16.5
Step-by-step explanation:
1) Work out what 1/5 of 12 is
To do this, we divide 12 by 5
12/5 = 2.4
2) Multiply 2.4 by 15
2.4 x 15 = 36
<em>If you don't like decimals, you can also do it this way...
</em>
This can be rewritten as 15 x 1/5 x 12
Multiplications alone can be performed in any order
1) Work out what 1/5 of 15 is
1/5 of 15
15/5 = 3
2) 3 multiplied by 12
3 x 12 = 36
