A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%
Answer:
-0.0526
Step-by-step explanation:
Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).
Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is
and probability of failure is
. For a win, X takes value 35 and for a loss X takes value -1. So the model is,
![P(X=35) = \frac{1}{38}](https://tex.z-dn.net/?f=%20P%28X%3D35%29%20%3D%20%5Cfrac%7B1%7D%7B38%7D%20)
![P(X=-1) = \frac{37}{38}](https://tex.z-dn.net/?f=%20P%28X%3D-1%29%20%3D%20%5Cfrac%7B37%7D%7B38%7D%20)
![P(X=i) = 0 \;if\; i \neq 38, i\neq -1](https://tex.z-dn.net/?f=%20P%28X%3Di%29%20%3D%200%20%5C%3Bif%5C%3B%20i%20%5Cneq%2038%2C%20i%5Cneq%20-1%20)
The mean for one bet is ![E(X) = \sum xP(X=x) = 35\times\frac{1}{38} - 1\times\frac{37}{38} = -0.0526](https://tex.z-dn.net/?f=%20E%28X%29%20%3D%20%5Csum%20xP%28X%3Dx%29%20%3D%2035%5Ctimes%5Cfrac%7B1%7D%7B38%7D%20-%201%5Ctimes%5Cfrac%7B37%7D%7B38%7D%20%3D%20-0.0526%20)
Answer:
Weakest value = 0.0196
Strongest value = 0.5929
Step-by-step explanation:
Given:
Choices
0.691
-0.14
-0.24
-0.77
Computation:
0.691² = 0.477481
-0.14² = 0.0196
-0.24² = 0.0576
-0.77² = 0.5929
Weakest value = 0.0196
Strongest value = 0.5929
The answer is A
if you add them all together, there are 15 employees, and only 5 have at least 10 years of experience. 5/15 simplifies to 1/3
