X is around 8.66666666, so you could possibly but that in fraction form like 8.666666/1 (8.6 repeating) and put it over one. I hope this helps!
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.

Step-by-step explanation:
Given
(5y + 6)² = 24 ( take the square root of both sides )
5y + 6 = ± 
= ± 2
( subtract 6 from both sides )
5y = - 6 ± 2 ( divide both sides by 5 )
y = 
and y = 
Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
