Answer is E. u could plug in the values for x and see if u get the same y in the equation
Answer: a. Number of visitors
b. average() amount spent per person by visitors to the park
c. Yes , we know the average amount spent per person byvisitors to the park. It is $28 per person.
Step-by-step explanation:
- A population is a group of all members according to the researchers's subject of interest.
- A parameter is a number that gives the measure of a factor generated from population (for ex Population mean () , population proportion (p) ).
- A sample is a finite subset of the population that represents the population in an analysis.
- A statistic is a number that gives the measure of a factor generated from sample (for ex sample mean () ,sample proportion () ).
For the given situation, A researcher wishes to estimate the average amount spent per person by visitors to a theme park.
Population by researcher's point of interest : "Number of visitors"
Parameter of interest : "average() amount spent per person by visitors to the park"
Since he takes a random sample of forty visitors and obtains an average of $28 per person.
Here , sample : forty visitors
And average amount spent per person by visitors to the park from sample :
$28 per person.
The sample means is the best point-estimate for the population mean.
So , the best point-estimate for average amount spent per person by visitors to the park here is $28 per person.
Answer:
The answer is 0.426
Step-by-step explanation:
10 to the power of 2 is 100 because 10 x 10= 100 when you divide a decimal by 100 just move the decimal point 2 times to the left
Complete question is;
Mia is tracking her savings account balance. She knows the equation y = 8000p^(t) can be used to find her balance y in any year t, but she can't remember what p represents. Her balance 3⅔ years after opening her account, is $9,905.54. What is the value of p?
Answer:
p = 1.06
Step-by-step explanation:
We are told that the equation y = 8000p^(t) can be used to find her balance y in any year t.
Now, we are given t = 3⅔ = 11/3 years
Also, we are given balance after 11/3 years as;
y = $9,905.54
Thus;
Plugging the relevant values into y = 8000p^(t), we have;
9,905.54 = 8000p^(11/3)
p^(11/3) = 9905.54/8000
p = (9905.54/8000)^(3/11)
p = 1.06
To the nearest hundred is 800
