The sampling distribution for a goodness of fit test is the a. Poisson distribution b. t distribution c. normal distribution d.
Dmitriy789 [7]

The chi-square distribution serves as the sampling distribution for the goodness of fit test since it quantifies how well the distribution derived from the data fits the empirical distribution.

<h3>What is sampling distribution?</h3>

The sampling distribution is the probability distribution of a statistic that is obtained by repeated sampling of a certain population. The mean or mode of a population's mean or mode of a variable is one example of the many different choices for a statistic that are described in this passage. The sampling distribution of a proportion is obtained by repeating your survey or poll for each possible sample of the population. For instance, instead of asking 1,000 cat owners what cat food they prefer, you could conduct a number of polls.

Archimedes drained the water in his tub. 62.562.562, point, 5 liters of water were drained each minute, and the tub was complete
erma4kov [3.2K]

Answer:

500 liters

Step-by-step explanation:

We want to find the total amount of water that was drained.

He drained 62.5 liters of water per minute and this went on for 8 minutes. The total amount of water drained is:

62.5 * 8 = 500 liters of water

If (h + h) · (h. h) = 16, find the value of h.<br> — HELP ME PLEASEEEE
yKpoI14uk [10]

Answer:

h = 2

Step-by-step explanation:

I'm assuming your periods are multiplication signs.

(h + h) X (h X h) = 16

When adding two variables like the first set of parentheses, it would become 2h.  When multiplying two like variables, you add the exponents.  h is the same as writing h¹.  So h¹ x h¹   gives you the answer of h².

So now your equation would look like:

2h  X  h²  = 16

As above, when you multiply two like variables you would add the exponents.  Also if any number are in front of the variable you would multiply those numbers.  So you have 2h¹ x 1h² and that would be 2h³.  If it had been

2h¹ x 2h², your answer would have been 4h³.

But so far you have 2h¹ x 1h² = 16

2h³ = 16

Dividing both sides by 2 you get

h³ = 8

To find h you have to take the cubed root of 8.  What number multiplied by itself 3 times gives you 8?    2 x 2 x 2 = 8     2 x 2 = 4 and x 2 = 8.

h = 2

If you put this into the original equation you have:

(2 + 2) x ( 2 x 2) = 16

 ( 4 ) x ( 4 ) = 16

A hyperbola centered at the origin has a vertex at (9, 0) and a focus at (−15, 0). Which are the equations of the asymptotes? y
chubhunter [2.5K]
Well, we know is centered at the origing, thus h,k are just 0,0.

using the provided vertex and focus point, gives us a distance for "a" of 9 and a distance for "c" of 15, check the picture below.

\bf \textit{hyperbolas, horizontal traverse axis }\\\\&#10;\cfrac{(x- h)^2}{ a^2}-\cfrac{(y- k)^2}{ b^2}=1&#10;\qquad &#10;\begin{cases}&#10;center\ ( h, k)\\&#10;vertices\ ( h\pm a,  k)\\&#10;c=\textit{distance from}\\&#10;\qquad \textit{center to foci}\\&#10;\qquad \sqrt{ a ^2+ b ^2}\\&#10;\textit{asymptotes}\quad  &#10;y= k\pm \cfrac{b}{a}(x- h)&#10;\end{cases}\\\\&#10;-------------------------------

\bf \begin{cases}&#10;a=9\\&#10;c=15&#10;\end{cases}\implies c=\sqrt{a^2+b^2}\implies \sqrt{c^2-a^2}=b&#10;\\\\\\&#10;\sqrt{15^2-9^2}=b\implies \sqrt{144}=b\implies \boxed{12=b}\\\\&#10;-------------------------------\\\\&#10;asymptotes\qquad y=0\pm\cfrac{12}{9}(x-0)\implies y=\pm\cfrac{4}{3}x
