Answer:
0.4
Step-by-step explanation:
These are the relative frequencies of each face (data are missing in the text of the problem):
Number Showing on Top Face Frequency
1 0
2 3
3 3
4 6
5 3
6 5
The probability to obtain a certain number when throwing the dice is given by

where
is the relative frequency of the number
to occur
is the sum of the relative frequencies
Here the sum of the frequencies is:

For number 5 here, we have:
(from the table)
So the probability of getting a 5 is

For number 6 here, we have

So the probability of getting a 6 is

So the probability to obtain either a 5 or a 6 in the next rolling is:

Irrational as 0.75 x 0.75 x 3.14......
Formula for the area of a face of a cube: A = length x width
Let's find the area of one face.
A = 5 x 5
A = 25
Now, let's multiply the area of one face by 6 because a cube has 6 faces.
25 x 6 = 150
A = 150 square centimeters
Hope this helps! :)
Answer:
40x - 300,000
7,500
Step-by-step explanation:
profit = revenue - cost
p(x) = 75x - (35x + 300,000)
p(x) = 40x - 300,000
Break even is when profit is zero
40x - 300,000 = 0
40x = 300,000
x = 7,500
