1 answer:
Using proportions, it is found that the amount of the novel she would have read is:
D. 14/15.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:
Hence option D is correct.

Answer:
Step-by-step explanation:
Before you add 2 fractions, the denominator needs to be the same. If they are the same, which they are, then add the 2 numerators.
1 plus 2 equals 3.
So the answer is 3 over 5.
Answer and Step-by-step explanation:
To calculate a confidence interval for a proportion:
1) Determine the proportion
p = 0.616
2) A 90% confidence interval has z-score that is 1.645.
3) Calculate margin of error
where
n is the sample size
So
ME = 0.02175
Then the interval is given by
p ± z(ME)
0.62 ± 1.645(0.02175)
0.62 ± 0.035
The interval will be
0.585 < p < 0.655
What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.
