The median and mode of the given data is 30 and 32 respectively.
Step-by-step explanation:
Given,
The number of stories in 11 buildings are 17,19,20,21,24,30,33,37,38,40,40
To find the median and mode of the data.
Formula
Mean = sum of the data ÷ number of terms
If the number of term is odd, the median = th term
Mode = 3 Median - 2 mean
Now,
Mean = (17+19+20+21+24+30+33+37+38+40+40)÷11 = 29
Median = th term = 6th term = 30
Hence,
Mode = 3×30-2×29
= 90-58 = 32
Answer:
x = 1178 games
Step-by-step explanation:
Let the number of games = x
Let the total cost = Tc
Let the total revenue = Tr
Given the following data;
Investment = $10,000
Cost of each game = $1.50
Selling cost = $9.99
Total cost, Tc = (Cost of each game * Number of games) + Investment
Tc = 1.50x + 10000
Total revenue, Tr = Selling cost * Number of games
Tr = 9.99x
Breakeven point is when total cost is equal to total revenue;
Tc = Tr
x = 1177.86 ≈ 1178 games.
<em>Therefore, the number of games that must be sold before the business breaks even is 1178 games. </em>
