Answer:

The Domain is where the line on your graph crosses the X axis.

The Range us where the line on your graph crosses the Y axis

And a arrow means it goes Into infinity

Step-by-step explanation:

Say you Have a line, it crosses the X axis at -3, your Domain would be -3!

Now say this line crosses the Y axis at -6, Your Range would be -6!

And now say if instead of the line ending at a dot after crossing -6 It has a arrow, that means you have infinity, Making your range instead of -6 it's be infinity! (If the arrow points up it's positive infinity, If the arrow points down it's negative infinity)

So for the first 2 numbers your answer would be [-3,-6] and in you have infinity itd be [-3, infinity) parenthesis isn't a error btw if you still don't get it I can just reply with a sheet I have on it

What is 2.5 x 7/10 =? and how did you get the answers?

Ivan

Answer:

1.75 or $\frac{35}{2}$

Step-by-step explanation:

2.5 * 7/10 is just like 2.5 * 0.7

so 2.5 * 0.7 = 1.75

You could also convert 2.5 to fraction which is 25/10

so you would have $\frac{25}{10} * \frac{7}{10}$ = $\frac{175}{100}$ reduced would equal $\frac{35}{2}$

How this helps you! :)

Answer:

The confidence interval would be more narrow if the confidence level were changed to 90%

Step-by-step explanation:

For a small sample size of n = 18 a pivotal quantity that we can use to form a confidence interval for $\mu$ is given by $T=\frac{\bar{X}-\mu}{S/\sqrt{n}}$ that has a t distribution with (n-1) degrees of freedom. We find a $100(1-\alpha)$ % confidence inverval using $P(-t_{\alpha/2}\leq T \leq t_{\alpha/2}) = 1-\alpha$ , where $t_{\alpha/2}$ is the t-value such that there is an area equal to $\alpha/2$ above this t-value and below the curve of the density of the t distribution with n-1 df. We find a 95% confidence interval with $P(-t_{0.025}\leq T\leq t_{0.025}) = 0.95$ and we find a 90% confidence interval with $P(-t_{0.05}\leq T\leq t_{0.05}) = 0.90$ . Because of $-t_{0.025} < -t_{0.05}$ and $t_{0.05} < t_{0.025}$ , the confidence interval would be more narrow if the confidence level were changed to 90%.
