<h2>80</h2><em>Step-by-step explanation:</em>
The fastest and simplest way I got it is this...
There are 9 small squares that make up one big square, right?
The 5 out of 9 squares are shaded.
The area of the whole square is 144 (12 times 12).
The logical thing to do is figure out what's 5/9 (five-ninths) of 144.
So I believe the answer is 80.
Hope that helped! Tell me if it did, I don't want to mislead people. (So can I have brainliest?)

Answer:
The value of the test statistic is
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
In this problem, we have that:
Then
The value of the test statistic is
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.
