At a certain time, the number of people that enter an elevator is a Poisson random variable with parameter λ. The weight of each

person is independent of other person’s weight, and is uniformly distributed between 100 and 200 lbs. Let Xi be the fraction of 100 by which the i th person exceeds 100 lbs, e.g., if the 7th person weighs 175 lbs, then X7 = 0.75. Let Y be the sum of the Xi .(a) Find MY(s).(b) Use MY(s) to find E[Y].(c) Verify your answer to part (b) by using the law of iterated expectations.

Whixh statement is true about the graphs of the functions shown below?
Nata [24]

Answer:

Step-by-step explanation:

Since G(0) = g(0) = 20, the parabolic graphs of these functions share a y-intercept:  (0, 20).

Completing the square puts these equations into vertex form, which simplifies comparisons of the graphs:

G(x) = 2x^2 - 12x + 20 becomes

          2(x^2 - 6x + 9 - 9) + 20, or

          2(x - 3)^2 - 18 + 20, or 2(x - 3)^2 + 2.  Comparing this result to

          a(x - h)^2 + k, we see that the vertex is located at (3, 2).

Going through the same process for g(x) 2x^2+12x+20, we get:

g(x) = 2(x + 3)^2 + 2, whose vertex is at (-3, 2).

Next time, please include ALL info pertaining to your question, including the set of possible answer choices.  Thank you.

Help me with this please and thank you!! :)
Ann [662]

Answer:

Step-by-step explanation:

  • A \cap C denotes the set of elements in both A and C, which is \{20, 24, 28\}.
  • B^{C} denotes the complement of set B, which is the set of all elements that are in the universal set that are not in set B. In this case, this set is \{3, 4, 5, 6, 8, 11, 13, 16, 17, 19, 20, 22, 23, 24, 25, 26, 27, 28\}

HELP PLEASE !!!! Rosana used linear combination to solve the system of equations shown. She did so by multiplying the second equ
Allisa [31]
She must have multiplied it by 5.

That would've given her:

x - y = 15
2.5x + y = 25

Now we can add them and the y-terms will eliminate each other. Because one is -y, and the other is positive y. -y + y = 0.
