Answer:
25%
Step-by-step explanation:
30 is what percent of 120
Is means equals
of means multiply
30 = P * 120
Divide by 120 on each side
30/120 = P*120/120
1/4 = P
.25 = P
Now put this in percent form
.25 * 100% = P
25 % = P
The moment generating function (mgf) of y is given by

Since the momoent generating function of x is given by

When p tends to 0, we have

Applying L'Hopital's rule we have:

This shows that y converges to <span>a chi squared random variable with 2r degrees of freedom</span>.
Answer:
yes, it is
Step-by-step explanation:
plug in the point (1, -1) (x,y) into the equation y = 9x - 10
-1 = 9(1)-10
-1 = 9-10
-1=-1
Answer:
-3y = 2x - 7
y = -2/3x - 7/3
Step-by-step explanation:
y cannot be negative nor a whole number.
To get y by itself you have to divide the -3 over to the other side.
