The solution of the expression ( -x²y)/(-xy)² will be ( -1 / y).
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
( -x²y)/(-xy)² = ( -x²y)/(-x²y²)
Divide -x² by -x² it will become -y / y²
= -y / y²
Divide -y by -y² then it will become -1 / y.
= -1 / y
Therefore, the solution of the expression ( -x²y)/(-xy)² will be ( -1 / y).

Answer:
he paid 168.75
Step-by-step explanation:
multiply 225 by .25 and you would get 56.25 and then subtrsct that from 225 and you would get your answer od 168.75
<h3>
The both events are <u>
not independent</u>
as the intersection of outcomes of both the events is 3 and not equal to Ф.</h3>
Step-by-step explanation:
Here, the total number of cards in a deck = 52
The total number of heart cards = 13
The total number of red faces in the deck = 6 ( 3 of heart and 3 of diamonds)
Now, out of the TOTAL 6 red face cards, 3 are of hearts.
So, (Red cards) ∩ (Heart cards) = 3 cards ( J, Q and K)
Now let E : Event of picking card which is of heart.
![P(E) = \frac{\textrm{Total number of red hearts}}{\textrm{Total cards}} = \frac{13}{52} = (\frac{1}{4})](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%5Cfrac%7B%5Ctextrm%7BTotal%20number%20of%20red%20hearts%7D%7D%7B%5Ctextrm%7BTotal%20cards%7D%7D%20%20%3D%20%5Cfrac%7B13%7D%7B52%7D%20%20%3D%20%28%5Cfrac%7B1%7D%7B4%7D%29)
So, the probability of picking a heart = ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Now let F : Event of picking card which is of red face.
![P(E) = \frac{\textrm{Total number of red faces}}{\textrm{Total cards}} = \frac{6}{52} = (\frac{3}{26})](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%5Cfrac%7B%5Ctextrm%7BTotal%20number%20of%20red%20faces%7D%7D%7B%5Ctextrm%7BTotal%20cards%7D%7D%20%20%3D%20%5Cfrac%7B6%7D%7B52%7D%20%20%3D%20%28%5Cfrac%7B3%7D%7B26%7D%29)
So, the probability of picking a red face card = ![\frac{3}{26}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B26%7D)
Hence, the both events E and F are <u>not independent</u> as the intersection of outcomes of both the events is 3 and not equal to
