The answer is 25% of 250 that is 62.5. If you round off it will be 63
Answer:
10.6 and 9/10
Step-by-step explanation:
To better understand the expression let us reformat it as
-10.6+ (9/10) + (2/5)m - 2.4n + 3m
From the above expression we now have a better knowledge/ idea of how the constant terms
The constant terms are terms/numbers standing alone without an attached variable, they are independent.
The constants are
-10.6 and 9/10
The triangle (call it <em>T </em>) has base and height 4, so its area is 1/2*4*4 = 8. Then the joint density function is
where <em>T</em> is the set
(a) I've attached an image of the integration region.
(b) <em>X</em> and <em>Y</em> are independent if the joint distribution is equal to the product of their marginal distributions.
Get the marginal distributions of one random variable by integrating the joint density over all values of the other variable:
Clearly, , so they are not independent.
I think that is a and c and b isbejejejjeejje
