<span>may result in an expected value that is even, odd, or a decimal.</span> The expected value is equal to the product of the theoretical probability of rolling a 2 on 1 die roll, or <span>1/6</span>,
and the number of die rolls. A total of 300 rolls gives an expected
value of 50, which is even. A total of 200 rolls gives an expected value
of 33.3, which is a repeating decimal. A total of 30 rolls gives an expected value of 5, which is odd.
Answer:
Interval within 1 standard deviation: (16.3,19.7)
Interval within 2 standard deviation: (14.6, 21.4)
Interval within 3 standard deviation: (12.9, 23.1)
Step-by-step explanation:
We are given the following in the question:
Population mean, 
= 18
Standard deviation, 
= 1.7
We have to find the following intervals:
Interval within 1 standard deviation:
Interval within 2 standard deviation:
Interval within 3 standard deviation:
4 more than a number = x + 4
is more than = >
thirteen = 13
x + 4 > 13
Thats easy the answer is b
Cost of goods = 1,500
Selling expense = 500
Total cost in selling = 1500 + 500 = 2000
Profit = Total Revenue - Total cost in selling = 3000 - 2000 = 1000
Profit = 1000
Hope this explains it.
