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;
The correct answer is A, or x + 1 = 4x + 5. We used the substitution method to replace y with x + 1.
Answer:
y = 2x - 81
Step-by-step explanation:
Equation in standard form:
Ax+By=C
We have:
3x-5+y=2y-4
3x+y-2y=-4+5
3x-y=1
Therefore:
A=3
B=-1
C=1
Answer: the equation in standard form would be: 3x-y=1; and the values of A, B and C would be: A=3; B=-1 and C=1.
Answer:
The answer would be -4.36.
