Answer:
-4
Step-by-step explanation:
Assuming that the following equation is correct, begin by solving the operations within parentheses and absolute value expressions.
|3 - 8| -
|-5| -
The absolute value of -5 is 5; -5 is five units away from 0. 12/4 is equal to 3.
5 -
5 - 9 = -4
The simplified expression is equal to -4.
The range of is the set of all real values
The function is given as:
The above function is a parent logarithmic function.
The parent logarithmic function have a range of the set of all real values
Hence, the range of is the set of all real values

Answer:
B
Step-by-step explanation:
In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:
Now we just need to solve for b:
and
so
Answer:
a. 19.68 miles per gallon.
b. 26.32 miles per gallon.
Step-by-step explanation:
Mean gas mileage (μ) = 23.0 mpg
Standard deviation (σ) = 4.9 mpg
In a normal distribution, for any length X, the z-score is determined by the following expression:
In a normal distribution, the 25th percentile (first quartile) of a normal distribution has a corresponding z-score of z = -0.677 and the 75th percentile has a corresponding z-score of z = 0.677
a. The first quartile of the distribution of gas mileage is
19.68 miles per gallon.
b. The third quartile of the distribution of gas mileage is
26.32 miles per gallon.
