To express sin O as a fraction in simplest term is 5/6
<h3>
How to determine the expression</h3>
Using the formula:
Sin O = opposite/ hypotenuse
Where opposite = The side directly opposite the angle
hypotenuse = The longest side of the triangle
Sin O = 5 / 6
Therefore, to express sin O as a fraction in simplest term is 5/6

The observed results would be very unlikely if the alternative hypothesis were true.
What does the alternative hypothesis mean?
A statement used in experiments using statistical inference is known as the alternative hypothesis. It is indicated by Ha or H1 and runs counter to the null hypothesis.
Alternatively, it is only a null-free option, as we can also state. An alternative theory is a claim that a researcher is testing in a hypothesis test.
What is an illustration of a different hypothesis?
Just like the null, the alternative hypothesis is an option. For instance, if your null is "I'm going to win up to $1,000" and your alternate is "I'm going to win $1,000 or more," you're essentially determining whether there is sufficient variance in the alternate hypothesis to allow you to reject the null hypothesis.

Answer:
Expenditure x (in hundreds of dollars) = $2,000
Step-by-step explanation:
Given:
Profit p (in hundreds of dollars)
Expenditure x (in hundreds of dollars)
p(x) = -0.5x² + 20x + 23
Find:
Expenditure for advertising .
Computation:
x = -(Cofficient of x) / 2(Cofficient of x²)
x = -(20) / 2(-0.5)
x = 20
Expenditure x (in hundreds of dollars) = 20 × $100
Expenditure x (in hundreds of dollars) = $2,000
