The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,
S = (n/2) (2a1 + (n - 1) x d)
Substituting the known values,
S = (365/2) (2 x 1 + (365 - 1) x 1)
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
The difference between fixed expenses and variable expenses is that fixed expenses do not change, regardless of how many items are produced. Variable expenses change based on the number of items produced.
An example of a fixed expense is the rent. The rent is always the same amount, regardless of production.
Materials would be a variable expense. You need enough material to make each item, so the more items you produce, the more material you need.
Answer:
g(0)=4^0 = 1
g(1) = 4^1 = 4
g(2) = 4^2 = 16
Average :
(1+4+16)/3
=(5+16)/3
=21/3
= 7
Take a sum, divide by 3 because the counted datas are 3.
Answer:
60
Step-by-step explanation:
A 3-digit number can be odd only when the third digit in it would be odd.
So,
The 3rd digit becomes the most limiting which can be (1, 3, or 5).
Now,
Since we have 3 alternatives to pick the third digit, it can be done in three ways. For every of these 3 ways, 5 digits will be left to select the 1st. Thus, the number of ways to select 3rd and 1st digit = 3 * 5 = 15 ways
After picking the 1st and 3rd digits, we are left with 4 ways to pick the other 4 digits. Thus, the total number of ways to select all the digits would be;
3 * 5 * 4 = 60 ways
Hence, 60 is the correct answer.
