The domain of the function is x > 0 and the range of the function is -∞ < f(x) < ∞
<h3>How to determine the domain?</h3>
The table represents a logarithmic function.
The domain represents the set of x values.
From the table, we can see that all the x values are positive values i.e. x > 0
Hence, the domain of the function is x > 0
<h3>How to determine the range?</h3>
From the table, the table outputs all zero, positive and negative numbers
This means that the range is the set of all real numbers.
Hence, the range of the function is -∞ < f(x) < ∞

One Fence Per Yard = $1.75
$73.50 - $3.50 (The Tax) = $70
$70 Divided by $1.75 = 40 Yards
Answer:
In order to calculate the expected value we can use the following formula:
And if we use the values obtained we got:
Step-by-step explanation:
Let X the random variable that represent the number of admisions at the universit, and we have this probability distribution given:
X 1060 1400 1620
P(X) 0.5 0.1 0.4
In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".
The variance of a random variable Var(X) is the expected value of the squared deviation from the mean of X, E(X).
And the standard deviation of a random variable X is just the square root of the variance.
In order to calculate the expected value we can use the following formula:
And if we use the values obtained we got:
