The function is f(x) = x^2 - 36. => y = x^2 - 36. To find the inverse function, you can exchange the variables (x,y) and the solve for the new y => x = y^2 - 36 => y^2 = x + 36 => <span>y = +/- sqrt of x + 36. So, the answer is +/- square root of the quantity x plus 36</span>
Answer:
-21
Step-by-step explanation:
put in -3 where x is
-3^2 9
-9-12 = -21
Answer:
The null hypothesis is 
Step-by-step explanation:
According to the Centers for Disease Control and Prevention, the proportion of U.S. adults age 25 or older who smoke is .22
This means that at the null hypothesis, it is tested if the proportion is in fact 0.22, that is:
A researcher suspects that the rate is lower among U.S. adults 25 or older who have a bachelor's degree or higher education level.
At the alternative hypothesis, it is tested if the proportion is lower than 0.22, that is:
Answer:
the second one would be more effective because $800*12 will cost a lot more than $650+2 months penalty if u leave
The random variable is the number of cars held up at the intersection.
A random variable is one whose value is aleatory, then you can not know anticipatedly the outcome for sure. In this case, the number of cars held up at the intersection may be different at any time inside the range given and you cannot know the number of cars that there will be in a future moment.
