Please provide the Box and whisker plot so that we can answer the question.
Answer:
C = 56.6 cm
Step-by-step explanation:
The circumference of a circle is
C = 2 * pi *r
C = 2 * 3.142 * 9
C =56.556
Rounded to 1 decimal place
C = 56.6 cm
Answer:
A) Linear Expression
Step-by-step explanation:
Answer:

Step-by-step explanation:
Geometric sequence
Each term in a geometric sequence can be computed as the previous term by a constant number called the common ratio. The formula to get the term n is

where
is the first term of the sequence
The problem describes Georgie took 275 mg of the medicine for her cold in the first hour and that in each subsequent hour, the amount of medicine in her body is 91% (0.91) of the amount from the previous hour. It can be written as
amount in hour n = amount in hour n-1 * 0.91
a)
This information provides the necessary data to write the general term as

b)
In the 8th hour (n=8), the remaining medicine present is Georgie's body is



Using the z-distribution, it is found that the 95% confidence interval for the proportion of all U.S. adults who play video games is (0.4681, 0.5119). It means that we are 95% sure that the true proportion of all U.S. adults who play video games is between 0.4681 and 0.5119.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have that:
- 95% confidence level, hence
, z is the value of Z that has a p-value of
, so
.
- 49% out of 2001 U.S. adults play video games, hence
.
The lower bound of the interval is:

The upper bound of the interval is:

The 95% confidence interval for the proportion of all U.S. adults who play video games is (0.4681, 0.5119). It means that we are 95% sure that the true proportion of all U.S. adults who play video games is between 0.4681 and 0.5119.
