A method for determining whether a critical point is a minimum. True or false?

Mathematics

Answer:

We can find if a critical point is a local minimum or maximum by looking at the second derivatives.

Step-by-step explanation:

If you take the first derivative, you will find the slope at the given point, which if it is a minimum or a maximum will be 0.

Then we take the second derivative. If that number is a positive number, then we have a local minimum. If it is a negative number, then it is a local maximum.

Answer:

1,3,5

Step-by-step explanation:

81 is a perfect square so it can be written as an integer

11.8 is rational because it can be written as a fraction (107/9)

sqrt(6) isn't a perfect square so it is irrational

3/7 is a fraction so it is rational

Answer:

D. \frac{2}{5}

Step-by-step explanation:

Since we know that the odds of an events can be found by dividing the probability that an event will occur by the probability that the event will not occur.

\text{Odds of an event}=\frac{\text{Probability that event will occur}}{\text{Probability that event will not occur}}

Probability of an event not occurring can be found by subtracting probability of the event occurring from 1.

\text{Odds of an event}=\frac{\text{Probability that event will occur}}{1-\text{Probability that event will occur} }  

We have been given that probability of an event is 2/7.  

Upon substituting our given values in above formula we will get,

\text{Odds of the given event}=\frac{\frac{2}{7}}{1-\frac{2}{7}} }

\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{7-2}{7}} }

\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{5}{7}} }

\text{Odds of the given event}=\frac{2}{7}\times \frac{7}{5}

\text{Odds of the given event}=\frac{2}{5}

Therefore, the odds of the same event are \frac{2}{5} and option D is the correct choice.
