Answer:
14.8
Step-by-step explanation:
If you are allowed a calculator, the formula to find the percentage is found by multiplying the percentage by the whole number. For example, when you put in the calculator, 18.5% x 80= 14.8
14.8 being your answer. I hoped this helped!
Let's create a table, and use arbitrary values of x between -3 and 3 (if the solution is not in this interval, we can use another one later). If we call:

We want to find the x's for with f(x) = 0
This is the table:
And now we can evaluate f(x) in each value of x to complete the table:

The table is:
If we use this values and plot them in the cartesian plane.
We get:
And now if we plot a line that connects the points, we get the graph of the quadratic equation:
Since the problem ask us to find the value of x for which f(x) = 0, we can see both in the table and in the graph that this value is x = 2
Answer:
The answer is "0.0547".
Step-by-step explanation:

Using the binomial distribution:

Calculating the excel formula:


The answer is 200 because 100 plus 100 equals 200
