Answer:
0.674
Step-by-step explanation:
If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is
and its cumulative distribution function (CDF) is
So, <em>the probability that X is less than 28 minutes is
</em>

Answer: M{x°}=89
A triangle has 3 sides, and the total degree is 180°. So make a equation to find the third degree (x).
Step-by-step explanation:
if a^2 +b^2 <c^2,
then abc is not a right triangle since for a right triangle a^2+ b^2 = c^2
So it says that Y, is K times X. So X times blank is Y. In 2 and 8, 2 times what is 8? the answer is 4. Same with 3 and 12. 3 times 4 is 12. etc. The answer is 4.
