Okay. It would be written like this: n/7 - 2 = 10. Add 2 to both sides and then you get n/7 = 12. Multiply by 7 to isolate the “n”. Then, you should get n = 84. Plug it in. 84/7 is 12. 12- 2 = 10. There. n = 84.
Answer:
anything less than 133 would be true
Step-by-step explanation:
35 ≥ 0.15m + 15
solve for m
subtract 15 from both sides
20 ≥ 0.15m
divide both sides by 0.15
133.33 ≥ m
m cannot be more than 133 minutes

Answer:
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
The lower bound of the interval is:
The upper bound of the interval is:
In this problem, we have that:
So
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
Answer:
Answer:
Domain is
All real number except at x=0
Step-by-step explanation:
We are given
Firstly, we will find (fog)(x)
now, we can plug back g(x)
Domain:
we know that domain is all possible values of x for which any function is defined
and we know that denominator of any function can not be zero
so, we set denominator =0
so, function will be defined for all values of x except at x=0
So, domain will be
All real number except at x=0
Hope this helps!
