Answer:
C. $29.20
Step-by-step explanation:
The difference between using an electric stove and a gas stove everyday is 13 cents - 5 cents= 8 cents.
Saving 8 cents everyday.
Therefore for a year, Bryce will save 8 cents × 365days = 2920 cents
Then 2920 cents = $(2920÷100)
=$29.20
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is 
The number of observation is 
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
The cost of 12.7 gallons gasoline at $2.15 each is $27.305 or $27.31.
You simply have to multiply 12.7 by $2.15 to get $27.31.
Hope this helps :)
Answer:
20
Step-by-step explanation:
0 to 1 = a difference of 1
1 to 2 = a difference of 2-1 = 1
===============
2 to 4 = a difference of 2
4 to 6 = a difference of 2
===============
6 to 9 = a difference of 3
9 to 12 = a difference of 3
===============
12 to 16 = a difference of 4
16 to 20 = a difference of 4
