Answer:
The probability of a customer buying carrots is 0.10.
Step-by-step explanation:
Here, given:
P (Customer buying apples) = 12%
⇒ P(A) = 12 \100 = 0.12
P(Customer Buying apples AND Carrots) = 5%
⇒ P(A ∩ C ) = 5 /100 = 0.05
P(Customer buying apples OR carrots ) = 17%
⇒ P(A∪ C) = 17/100 = 0.17
Now, we know that:
<h3>
P(X ∪ Y) = P(X) + P(Y) - P(X ∩ Y ) </h3><h3>
</h3>
Now, here substituting the values, we get:
P(A∪ C) = P(A) + P(C) - P(A ∩ C )
⇒ 0. 17 = 0.12 + P(C) - 0.05
or, 0.17 - 0.07 = P(C)
or, P(C) = 0.10
or, P(Customer Buying Carrots) = 0.10
Hence, the probability of a customer buying carrots is 0.10.
Answer:
![\$10.70](https://tex.z-dn.net/?f=%5C%2410.70)
Step-by-step explanation:
Let
x-----> the number of miles
y ---> the total charge in dollars
we know that
The total charge must be equal to the flat fee ($3) plus the number of miles multiplied by $1.10 per mile
so
The linear equation is
![y=1.10x+3](https://tex.z-dn.net/?f=y%3D1.10x%2B3)
For x=7 miles
substitute in the equation and solve for y
![y=1.10(7)+3](https://tex.z-dn.net/?f=y%3D1.10%287%29%2B3)
![y=\$10.70](https://tex.z-dn.net/?f=y%3D%5C%2410.70)
y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
