I assume you want the total of liters? 2 plus 1.5 equals 3.5 liters of juice all together :)

I'm Stuck On This Question Please Help Out

Brilliant_brown [7]

So with standard deviation, the greater it is the greater the spread is.

Since distribution 3 has the greatest standard deviation, it has the greatest spread.

What is the area of the entire triangle if the altitude is a perpendicular

kifflom [539]

Answer:

60cm^2

Step-by-step explanation:

use Pythagoras' theorem to find the height (attached)

24/2 = 12

h=5cm

are of a triangle = base x height /2

24 x 5 / 2 = 120/2 = 60

If y ?-x, and every Xi is i i d with a chi-squared distribution with 14 degrees of freedom, find the MGF of Y M(t) = What is the

Bumek [7]

Answer:

F. chi-squared(df-210)

Step-by-step explanation:

The Chi Square distribution is the distribution of the sum of squared standard normal deviates .

We have independent and identically distributed random chi square variables, each one with 14 degrees of freedom $X_i \sim \chi^2_{14}$ for $i=1,2,....,15$ . And let Y the random variable defined as :

$Y= \sum_{i=1}^{15}X_i$

We have a thorem that says that the distribution of Y is given by: $Y\sim \chi^2_{14+14+......+14=15*14=210}$

Proof

We need to find first the moment generating function for the random variable Y like this:

$M_Y (t) =\prod_{i=1}^{15}M_{X_i (t)}$

And the productory is satisfied because we have independent random variables. The moment generating function for a chi square distribution with r1 degrees of freedom is given by:

$M_X (t) =(1-2t)^{-\frac{r_1}{2}}$

And replacing for each of the 15 distributions we got :

$M_Y (t) =\prod_{i=1}^{15}M_{X_i (t)}= (1-2t)^{-\frac{14}{2}} (1-2t)^{-\frac{14}{2}}..... (1-2t)^{-\frac{14}{2}}$

And using properties of algebra we got this:

$M_Y (t) = (1-2t)^-{\frac{14+14+.....+14}{2}}, t$

And we can see that the moment generating function represent a chi square distribution with 14*15=210 degrees of freedom.

So then the correct option is given by:

F. chi-squared(df-210)
