Answer:
2 yards
Step-by-step explanation:
12 inches=1 ft
72 inches=1/12×72=6 ft
3 ft=1 yard
6 ft=1/3×6=2 yards
Given, Sylvie needs $110 for a concert ticket.
Sylvie has $16.
Her hourly earnings = $h
Sylvie is working 10 hours at her job.
She is getting in 1 hour = $h
So, 10 hours she will get = $ = $
So the total amount she has now = $16 + $(10h) = $()
So we can write the equation as,
110=16+10h
We can move 16 to the left side also. 16 is added to the right side. We can move it by using reverse operation of addition. Reverse operation of addition is subtraction. So we will subtract 16 from both sides. Subtracting 16 we will get,
110-16=16+10h-16
110-16=10h
We have got the required answer.
To find Sylvie's hourly income the correct options are option A and option D.
Answer:
The 95% confidence interval for the true proportion of all teams that had a season winning percentage better than 0.500 is (0.1853, 0.6147).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
.
For this problem, we have that:
8 out of the 20 teams in the sample had a season winning percentage better than 0.500. This means that 
.
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the true proportion of all teams that had a season winning percentage better than 0.500 is (0.1853, 0.6147).
