Answer: 16.7%
I took the k12 unit test
The inflation rate is given by the percentage error and is given by the equation A = 16.71 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the inflation rate of percentage error be represented as A
Let the cost of the Jolly Peanut butter be = $ 3.59
So , the original cost = $ 3.59
Let the increased rate of Jolly Peanut butter be = $ 4.19
So , the increased rate = $ 4.19
Now , the inflation rate is given by the equation
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Inflation rate A = ( ( 4.19 - 3.59 ) / 3.59 ) x 100
On simplifying the equation , we get
Inflation rate A = ( 0.6 / 3.59 ) x 100
Inflation rate A = 0.16713 x 100
Inflation rate A = 16.71 %
Therefore , the value of A is 16.71 %
Hence , the inflation rate is 16.71 %

50,60,72 find the 8th term airthmetic and geometric sequence
Answer:
8th term is 179.15904
Step-by-step explanation:
The sequence is geometric with a common ration = 6/5
r = 60/50 = 72/60 = 6/5
Use the formula
[tex]a_{n} = ar^{n - 1}[/tex]
In your case a = 50, r = 6/5 and n = 8
[tex]a_{8} = 50(6/5)^{8 - 1} \\ = 50(6/5)^{7} \\ = 50(279936/78125)\\ = 179.15904[/tex]

what is opportunity sampling
Answer:
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.

Melinda takes readings of the depth of water in a
pond every day for 1 week. Here are her results in
meters:
6.5, 6.8, 7.2, 6.8, 6.6, 6.3, 6.4
What are the mean, median, and mode water levels
for the week, rounded to the nearest tenth?
Answer with supporting work:
Answer:
a) The Mean of the water levels for the week (μ) = 6.657
b) The Median of the water levels for the week = 6.6
c) Mode = 6.8
Step-by-step explanation:
Step(i):-
Given that the data per one week
6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4
we have to find the mean of the given data
Solution:-
Mean = ∑x /n
[tex]Mean = \frac{6.5+6.8+7.2+6.8+6.6+6.3+6.4}{7}[/tex]
Mean = [tex]\frac{46.6}{7}[/tex]
Mean(μ) = 6.657
The Mean of the water levels for the week (μ) = 6.657
Step(ii):-
Given that the data per one week
6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4
we have to find the Median of the given data
A median is the center value of a given data when arranged in an order
6.3 6.4 6.5 6.6 6.8 6.8 7.2
The Median = middle of the given data
The Median = 6.6
Step(iii):-
Given that the data per one week
6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4
we have to find the Mode of the given data
Mode = Value repeated the most number of times
The value 6.8 repeated two times
∴ Mode = 6.8
