Answer:
amplitude = 2
Step-by-step explanation:
the amplitude is the distance from the x- axis(midline ) to the maximum value , that is
amplitude = 2
Answer:hello
Step-by-step explanation:
<h3>
Answer: Bottom left corner (southwest corner)</h3>

The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as
which is like saying 
Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

where
a is the initial value or y-intercept
b is the base of the exponential function
r is the rate in decimal form
b=(1+r)
In this problem we have
x ----> the number of days
y ----> the number of shoppers
a=120
r=10%=10/100=0.10
b=1+0.10=1.10
substitute the values

First day

Second day
For x=1 day
substitute the value of x in the equation and solve for y

Third day
For x=2 days

Fourth day
For x=3 days

Fifth day
For x=4 days

Sixth day
For x=5 days

Seventh day
For x=6 days

Adds the numbers

To find the range you subtract the largest number from the smallest 20-13=7. To find the interquartile range you have to find the median of the data set. The median is 18.5, now there are two sets split in half. The median for the lower quartile is 14.5 and the median for the upper quartile is 19. Range=7 and IQR=18.5-14.5=4. IQR=4
