Answer:
. The inverse function is y=x−24 .
Step-by-step explanation:
$115,850 (70%*$165,500) is the cost for the land and $49,650 (30%*$165,500) represents the cost for the building. The total cost for the land and the building is represented by the equation $165,500 (150,000 + [7%*$150,000] + $5000). The company must gain (70% and 30%) by dividing each of the values by the total value (($87,500+$35,000)/($87,500+$35,000+$52,500)for land; $52,500/($87,500+$35,000+$52,500) for building.
Answer:












And replacing we got:

And the best anwer is
10.12
Step-by-step explanation:
We have the following data given:
62 63 68 72 79 80 83 93 94 95
And we need to begin finding the mean with the following formula:

And replacing we got:

Now we can find the mean absolute deviation like this:










And finally we can find the mean abslute deviation with the following formula:

And replacing we got:

And the best anwer is
10.12
Answer:
P(X = x, Y = y) = f(x, y)
Step-by-step explanation:
Let X be a discrete random variable, and suppose that the possible values that it can assume are given by x1, x2, x3, . . . , arranged in some order. Suppose also that these values are assumed with probabilities given by
P(X = xk) = f(xk) k = 1, 2, . . . (1)
It is convenient to introduce the probability function, also referred to as probability distribution, given by
P(X = x) = f(x)
If X and Y are two discrete random variables, we define the joint probability function
of X and Y by
P(X = x, Y = y) = f(x, y)
where f(x, y) ≥ 0
