Answer:
the answers are : A , B , and E. i just took the assignment.
Step-by-step explanation:
Since the .16 is in the hundredths place, the fraction is 2 16/100, or 216/100
But if you need to simplify it it's 2 4/25, or 54/25
Answer: 12
Step-by-step explanation:
The formula to find the sample size is given by:-
, where
is the population standard deviation,
is the z-value for the
confidence interval and E is the margin of error .
As per given , we have
Population standard deviation : 
z-value for 95% confidence interval : 
Margin of error : E= 3
Then, the required minimum sample :-

Hence, the required minimum sample size = 12
1. Carl's constant rate of speed is the slope of the straight line graph.
This straight line passes through: (0,0), (5,1), (10,2) etc
We can use the slope formula with any two points to find the slope of this line.
The slope formula is
.
Let
and 
Then
,
.
Carl's speed is
miles per minute.
But we must leave our answer in miles per hour
Hence Carl's speed is
miles per hour
After 2 hours, Carl will travel
miles.
2. The given line has equation 
We write this in slope-intercept form by solving for y.

This is in the form
, where
is the slope.
When x=3, 

When x=3, y=22
3. The given straight line graph that models the situation passes through:
(0,0) and (20,30).
The slope of this line is
Therefore the rate is $ 15 per ticket.
If the theater sells 150 tickets, the earnings will be:
dollars.
