We have been given the function
We know that the range is set of y values for which the function is defined. Therefore, we will find the value for x and then observe the restriction is y's values.
Now, we know that logarithm function is not defined for negative values. Hence, the value for y is always greater than zero.
Therefore, the range of the function is given by y>0
B is the correct option.
Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have
This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k
The unit rate is the same that the slope
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2
Conditional relative frequency is the ratio of the the value of somthing with the total value for a set in data table. The value of the letter <em>a</em> is 0.1 and the value of the letter <em>b</em> is 0.85.
Given information
In the given table,
For the 16 year old weekend curfew is 0.9 before 10 pm and <em>a </em>after 10 pm in total 1.
For the 17 year old weekend curfew is <em>b</em> before 10 pm and 0.15<em> </em>after 10 pm in total 1.
There is total are with 0.88 before 10 pm and 0.12 after 10 pm in total of 1.
<h3>Conditional relative frequency-</h3>Conditional relative frequency is the ratio of the the value of somthing with the total value for a set in data table.
As for the relative conditional frequency the sum of the frequencies of each column should be equal to the one.
Hence for column two given in the table,
Solve for<em> a</em>,
Thus the value of the letter <em>a</em> is 0.1.
Hence for column three given in the table,
Solve for<em> a</em>,
Thus the value of the letter <em>b</em> is 0.85.
