We have the equation:

Given the slope-intercept formula for the equation of the line, we have the following:

Now, since we have that t is the number of hours the electrician spends working, the slope of the function represents the hourly rate charged.

Step-by-step explanation:
people define trapezoids to have one and only one pair of opposite sides parallel, Squares are quadrilaterals with equal side lengths and four right angles.
Answer:
30.5
Step-by-step explanation:
Let ;
Sunny = S ; Medium = M ; Cold = C
_____ S _____ M ___ C
__X : 50 ____ 35 ___ 10
P(X) : 0.2 ____ 0.5 __ 0.3
P(M) = 1 - (0.2 + 0.3)
P(M) = 1 - 0.5 = 0.5
Expected profit per day, E(X)
E(X) = sum of (X * p(x)
E(X) = (50 * 0.2) + (35 * 0.5) + (10 * 0.3)
E(X) = 10 + 17.5 + 3
E(X) = 30.5
