Drop the percent sign so that you only have 96 then divide by 100 to get the decimal (or move the decimal place to the left two).
96% --- drop the percent
96 ----- move the decimal place over to or divide by 100
96/100
96.0
.96
Answer:
1. We can see that salesperson's weekly income is the sum of her constant weekly salary ($760) and a commission which is variable and depends on her weekly sales.
So, if we say that y is her weekly income and x is her weekly sales, we can write this as:
y = 760 + 0.075x
Note that we had to change percentage to decimal number dividing it by 100.
2 Since for each value of x there is only one corresponding value of y, we can say that this is a function. For any value of x we input there is only one solution we get - that is the main feature of function and a way to tell if something is really a function.
Since this is a function, it can also be written as:
f(x) = 760 + 0.075x
3. Domain of a function is, basically, set of all values of x for which the function can work. That practically means that, since x is weekly sale, it can not be negative (one cannot make -$500 sale, for example). However, it is possible that she doesn't make a sale one week, making it possible for x to be 0. Also, the value of her sales doesn't have to be integer (it is quite possible that she makes $673.50 sale).
All this means that appropriate domain for this function are positive real numbers including 0.
Probability of an event is the measure of its chance of occurrence. The event out of the listed events whose probability is 0.2957 is given by : Option C: 
<h3>How to get the z scores?</h3>
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z-score.
If we have

(X is following normal distribution with mean
and standard deviation
)
then it can be converted to standard normal distribution as

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

Also, know that if we look for Z = z in z tables, the p-value we get is

Using the z-table, we get the needed probabilities as:
Case 1:

Case 2:

Case 3:

Case 4:

Thus, the event out of the listed events whose probability is 0.2957 is given by : Option C:
