Answer:
Step-by-step explanation:
A. 2x+3y+z
X = -2
Y= -3
Z= 5
2(-2)+3(-3)+5
-4-9+5
=8
B. X-Y
-2–3
-2+3
=1
C. 2(x+y/z)
2(-2-3/5)
2(-1)
=-2
D. 3x^2-2x+1
3(-2)^2-2(-2)+1
3(4)+4+1
=17
E.3y(x+x^2-y)
3(-3)(-2+-2^2-(-3))
-9(1)
=-9
F.-z^2(1-2x)/y-x
5^2(1-2(-2)/-3–2
25(5/5)
25(1)
=25

6 is answer...............
In order to find out where your holes and asymptotes are is to factor both the top and the bottom of that rational function. The numerator factors to (x+2)(x-2) and the denominator factors to x(x+1)(x-2). So since there is an (x-2) in both the numerator and denominator, that is called a removable discontinuity which we also know as a hole. The other factors in the denominator, the x and the (x+1) are vertical asymptotes, or values of x that make the rational function undefined (you're NEVER allowed to have a 0 in the denominator of a fraction!). So your correct choice is c. The way you find the y coordinate for the hole is to plug in 2 for x and solve it for y. No biggie.
Answer:
The expected number of vehicles owned to two decimal places is: 1.85.
Step-by-step explanation:
The table to the question is attached.
∑
Where:
E(X) = expected number of vehicles owned
∑ = Summation
x = number of vehicle owned
p(x) = probability of the vehicle owned

The expected number of vehicles owned is 1.85.
