Define x:
--------------------------------------------
Let the tie be x
Tie = x
Shirt = x - 4.02
--------------------------------------------
Construct equation :
--------------------------------------------
The sum of the shirt and tie is $75.62
x + x -4.02 = 75.62
2x - 4.02 = 75.62
2x = 79.64
x = $39.82
--------------------------------------------
Find the cost of tie and shirt :
--------------------------------------------
Tie = x = $39.82
Shirt = x - $4.02 = $39.82 - $4.02 = $35.80
----------------------------------------------------------------------------------------
Answer: The price of the short is $35.80

Answer:
Step-by-step explanation:
It is given that The probability a person is infected by a certain cold virus is 0.2 that is p=0.2, then q=1-0.2=0.8.
Now, we have to find the probability that at least one person will be affected by the cold virus, that is P(x>1).
P(x>1)=1-(P(x=0)+P(x=1))
=
=
=
=
=
=
=
=
Thus, probability that at least one person will be affected by the cold virus will be=0.726.
Answer:
The function
f(x) = x3 + 2x2 − x − 2
is a trinomial and it is expected that it has three factors corresponding to the three roots. The possible roots could 1, -1, 2, or -2. Trying out 1
f(1) = 1 + 2 - 1 - 2 = 0
According to the remainder theorem (x - 1) is a factor. By doing synthetic division
1 | 1 2 -1 -2
1 3 2
1 3 2 0
f(x) = (x - 1)(x2 + 3x + 2)
which can further be factored into
f(x) = (x -1)(x +1)(x + 2)
The three factors are
x-1
x+1
x+2
which are all linear expressions
