Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = , if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = = 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
Answer:
Step-by-step explanation:
Let<em> x</em> = 2 because x > 0
See which expression is equal to 4√22 when <em>x</em> = 2
The expression is option A
We will conclude that:
- The domain of the exponential function is equal to the range of the logarithmic function.
- The domain of the logarithmic function is equal to the range of the exponential function.
<h3>Comparing the domains and ranges.</h3>
Let's study the two functions.
The exponential function is given by:
f(x) = A*e^x
You can input any value of x in that function, so the domain is the set of all real numbers. And the value of x can't change the sign of the function, so, for example, if A is positive, the range will be:
y > 0.
For the logarithmic function we have:
g(x) = A*ln(x).
As you may know, only positive values can be used as arguments for the logarithmic function, while we know that:
So the range of the logarithmic function is the set of all real numbers.
<h3>So what we can conclude?</h3>- The domain of the exponential function is equal to the range of the logarithmic function.
- The domain of the logarithmic function is equal to the range of the exponential function.
