Answer:
16.5 meters
Step-by-step explanation:
The length of an arc of a circle = 2πr(C/360°) ;where:
C is the central angle of the arc,
R is the radius of the arc
Length of the arc = 2π(7)(135/360)
= 16.493
= 16.5 metres (approx.)

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:
x = 105°
Step-by-step explanation:
Question :
![\frac{12}{35} =\frac{36}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B35%7D%20%3D%5Cfrac%7B36%7D%7Bx%7D)
You can use cross multiplication to solve this.
Let us solve now
![\frac{12}{35} =\frac{36}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B35%7D%20%3D%5Cfrac%7B36%7D%7Bx%7D)
12 × x = 35 × 36
12x = 1260
Divide both sides by 12.
x = 105°
Hope this helps you :-)
