Answer:
Rewriting without an exponent we get
Step-by-step explanation:
We need to rewrite the following without an exponent.
We need to solve the exponent to find the result.
We know the exponent rule:
Now using this rule to solve the equation:
So, Rewriting without an exponent we get
Answer:
In average, houses in the particular area use 119,6 therms of gas during the month of January.
Step-by-step explanation:
The μ formula is:
μ= ΣXi/N
ΣXi= is the sum of each xi. xi is each observation in the sample.
N= Total number of observations.
For this case:
ΣXi= 125+103+118+ 109+ 122+ 82+ 99+ 138+ 151+ 149
ΣXi= 1196
N= 10
μ= 1196/10
μ= 119,6
In average, houses in the particular area use 119,6 therms of gas during the month of January.
