Please help! Problem is attached
Darya [45]

Answer:

  (a)  -3

Step-by-step explanation:

The value of f(x) approaches 3cos(π) = -3 as x approaches π from either direction. The limit is -3.

__

<em>Additional comment</em>

The fact that the function is defined to have a different value at x=π simply means there is a jump discontinuity there. The function is <em>not continuous</em>, because the limit and the function value differ. That doesn't detract from the fact that there is a limit, and it is -3.

1. Data are from a normal distribution and the mean is 20 with a standard deviation of 2. a. What % of observations fall between
tangare [24]

Answer:

P(18

And we can find this probability with the normal standard distribution and we got:

P(-1

Step-by-step explanation:

Let X the random variable that represent the variable of a population, and for this case we know the distribution for X is given by:

X \sim N(20,2)  

Where \mu=20 and \sigma=2

We are interested on this probability

P(18

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(18

And we can find this probability with the normal standard distribution and we got:

P(-1
