Answer:

Step-by-step explanation:

The complete question tells us  that;

A dataset from a government survey contains variables for 87 adults age from 18 to 85. The variables include iron level ( µ g/dL), cholesterol level (mg/dL), and systolic blood pressure (mmHg). The researchers built a multiple regression to predict the mean iron level based on 2 variables, cholesterol level and systolic blood pressure.A partial regression ANOVA table is provided. Complete the ANOVA table aning. Use a significance level of a 0.05. Regression ANOVA Table Source df SSMSF Statistic p-value regression104535226.5 error 84 53813 640.6 Give the degrees of freedom as a whole number, the value of F to at least two decimals, the the p-value to at least three decimals. Then form the conclusion based on your results.

Suppose that $g(x)=f^{-1}(x)$. If $g(-15)=0$, $g(0)=3$, $g(3)=9$ and $g(9)=20$, what is $f(f(9))$?
never [62]

Answer:

0

Step-by-step explanation:

\text{If } g(x)=f^{-1}(x);$ and:$\\g(-15)=0,$  g(0)=3,  g(3)=9,  g(9)=20

We are to determine the value of f(f(9)).

Now:

g(0)=f^{-1}(0)=3\\g(3)=f^{-1}(3)=9

From:

g(3)=f^{-1}(3)=9\\f(9)=3

From:

g(0)=f^{-1}(0)=3\\f(3)=0

Therefore:

f(f(9))=f(3)=0
