Answer:
The expected value of lateness 
hours.
Step-by-step explanation:
The probability distribution of lateness is as follows:
Lateness P (Lateness)
On Time 4/5
1 Hour Late 1/10
2 Hours Late 1/20
3 Hours Late 1/20
The formula of expected value of a random variable is:
Compute the expected value of lateness as follows:
Thus, the expected value of lateness hours.
Transitive Property of Equality<span>: If a = b and b = c, then a = c.
This is one of the equivalence </span>properties of equality<span>.
Hence, the answer is C.</span>
6.7*6.7 to find the surface area of the base which is 44.89
4*1/2*10.1*6.7 to fix the surface area of all four triangular faces which is 135.34
Plus them together 44.89+135.34 which is 180.23
The y intercept is 17. You can see it clearly in the equation.
