Answer:
Answer is 3
Step-by-step explanation:
x/3-2x/1+3 =x-3/5
x/3-x/3 = x-3/5
0=x-3/5
0=x-3
3=x
sothat, x = 3 ans

Answer:
B
Step-by-step explanation:
The transformation is proved through comparing the size of the bigger triangle to the smaller triangle in the individual sides. So the size of A F/ AB should be equal to AG / AC due to transformations making A F and AG the same times longer as AC and AB. By performing those calculations, you get 3.
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.
