Hope this helps!!!!!!!
looking at the two triangles, the smaller triangle was reduced by a factor of 3.
the value of the missing side can be gotten by multiplying the corresponding side in the smaller triangle by 3
the value of the missing side is 12
Answer:
Step-by-step explanation:
For this case we can use the moment generating function for the normal model given by:
And this function is very useful when the distribution analyzed have exponentials and we can write the generating moment function can be write like this:
And we have that the moment generating function can be write like this:
And we can write this as an infinite series like this:
And since this series converges absolutely for all the possible values of tX as converges the series e^2, we can use this to write this expression:
and we can use the property that the convergent power series can be equal only if they are equal term by term and then we have:
And then we have this:
And then we can find the
And we can find the variance like this :
And first we find:
And then the variance is given by:
Answer:
v=7
Step-by-step explanation:
You want to write your equation and it should look like this:
12 - 3V+ 12Y = 4
next you wanna plug in y which in this case it is 3 now your equation should look like this:
12 - 3V+ 12(3) = 4
next you wanna multiply 12 and 3 so keep everything the same your new equation should look like this:
12 - 3V+ 36 = 4
now you wanna combine like terms and the like terms here would be 12 and 36 so you wanna subtract 12 from 36 to get you 24 and your new equation should look like this:
3V+ 24 = 4
next you want to subtract 24 from 4 and it should look like this:
3V= -20
now you want to get the variable by itself and you can do that by dividing 3 from -30 and your new equation should look like this:
v=-6.666666666666667
but you cant submit that so you wanna say v=7

<u><em>If you ask '' How do I solve these questions?'' I say:</em></u>
<em>We look at the tens digit to find the nearest hundred. If the number is 1,2,3 or 4, the tens and ones digit is reset. If it is 5,6,7,8 or 9, another hundred is added to the hundreds place of the number. The remaining tens and hundreds digits are reset</em>.
