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.
First, let's convert 0.77 to a fraction.

Multiply by 100

Now make the denominators the same, to make it easier to find which fraction is greater. We can do this by finding the LCM of the denominators, then however many times the denominator goes into that number, we multiply the numerator by the same amount.
For example, the LCM of 100 and 6, is 300. 6 goes into 300 50 times, so the numerator for 4/6 is 200 (4 x 50 = 200). :)

The answer is 0.77 is greater than 4/6. :)

Answer:
surface area of cuboid=2(lb+bh+hl)
surface area of cuboid=2(12×5+5×2+2×12 )
surface area of cuboid=188in²
One quarter (25%) of the data is in any quartile. That is the meaning of the term "quartile."
25% of data is in quartile 1
If x=2, the equation would be 6 (2) + 3y = 15.
This simplifies to 12 +3y = 15. Subtract 12 from both sides and you get 3y = 3. Divide both sides by 3 and you get y = 1.
So if x = 2, y =1
If x = 5, the equation becomes 6 (5) + 3y = 15.
This simplifies to 30 + 3y = 15. Subtract 30 from both sides and you get 3y = -15. Divide both sides by 3 and you get y = -5.
So if x =5, y = -5.
I hope this helps!
