Answer:
a) Computing the expected value E(XY) gives 1/4
b) The probability density function fZ(z) of Z = XY is calculated in the attached picture.
c) Computing E(Z) gives 1/4
Step-by-step explanation:
Comparing the computation of E(Z) using the answer to b), it shows that the values are equal.
Answer:
Hello! answer: x = 15
Step-by-step explanation:
Here is a visual i created of what the complementary angle would look like!
The formula is
A=p e^rt
A future value 900
P present value 800
E constant
R interest rate 0.11
T time?
We need to solve for t
T=[log (A/p)÷log (e)]÷r
T=(log(900÷800)÷log(e))÷0.11
T=1.07 years round your answer to get 1 year
Answer:
<em>0.5 < x < 14.5</em>
Step-by-step explanation:
<u>Triangle Inequality Theorem
</u>
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining those inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We are given two of the triangle side lengths as y=7.5 and z=7, thus the third side length (x) can be in the range:
7.5 - 7 < x < 7.5 + 7
0.5 < x < 14.5
<u>Note: The latter is the correct answer but none of the choices is accurate. Choice D is closer to the correct answer but the endpoints cannot be included.</u>
Answer: About 5.8 mph.
Step-by-step explanation: Divide 26.2 by 4.5 and it’ll give you 5.82222222... round to the nearest tenth and you get 5.8
