The correct one would by 9h because you are asking how much will Ursula make per hour. So let's say that h is 10, then in order to know how much Ursula makes per hour, you have to add 9 ten times. A short way to do that would be to simply multiply 9 with 10 so that you can get the answer of 90. It cannot be 9/h because then answer will be much lower than it is supposed to be. So the answer to the question is really 9h.
I think it would be 300, because 15% of x=45, so .15x=45, x= 45/.15=300

Using correlation coefficients, it is found that a coefficient of -1 represents a strong negative correlation.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
For this problem, we have a correlation coefficient of -1, hence it means that:
- The relation is negative, as -1 is a negative number.
- The relation is strong, as the absolute value of the coefficient is of 1, which is greater than 0.6.
