Answer:
Expected number of matches that occur = 4 matches
Step-by-step explanation:
First of all, let X_i be the event that when we turn over card i if it matches the required cards face.
Thus, for example X_1 is the event that turning over one card results in an ace while X_2 is the event that turning over second card reveals a deuce.
The number of matched cards "N" is given by the sum of this indicator random variable as shown in the attached file;
Anything below 2 would fit into the inequality
7x = 35 (divide by 7 on both sides to get x by itself)
x = 5
Answer:The answer is 0.1875, or 3/16 (in fraction form)
Step-by-step explanation: 3/4 divided by 4, (a square is equal on all 4 sides)
And there you have it!!!

Answer:
A
Step-by-step explanation:
A is equal to 5d-5
I just went through all eh choices
It can’t be b or c becuase when distributed, it automatically is -5d+25 or vice versa with a different sign so their out
D is impossible becuase you can’t jsut flip a subtraction problem
And A is possible because adding a negative basically means subtracting so if flipped The signs have to change
