Using the Pythagorean theorem we can find the distance from the swimming pool to the courthouse:
Swimming pool to courthouse:
Distance = √(3^2 + 4^2)
Distance = √(9+16)
Distance = √25
Distance = 5 kilometers
Now total the distance the bird flew:
Courthouse to Library is given as 3 kilometers.
Library to swimming pool is given as 4 kilometers
Swimming pool to courthouse we calculated as 5 kilometers.
Total distance = 3 + 4 + 5 = 12 kilometers.
Answer:
Step-by-step explanation:
12 boxes of hay
1.50*12 = $18
18 < 1800 so that is not true, she made a mistake.
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.
I am not sure about point slope, but I can find an equation in slope-intercept form and convert it, so
y=mx+b, m=slope
slope=(y1-y2)/(x1-x2)
we have points
(4,5)
(-3,-1)
(x,y)
x1=4
y1=5
x2=-3
y2=-1
subsitute
(5-(-1))/(4-(-3))=(5+1)/(4+3)=6/7
y=6/7+b
sybsitute and solve for b
(4,5)
x=4
y=5
5=6/7(4)+b
5=24/7+b
5=35/7
subtract 24/7 from both sides
11/7=b
y=6/7x+11/7
convert to the point slope form and find equivilent fraction
since the question asks for 2 answers that are correct and only 2 of the equations have slope of 6/7 I can guess that the answers are B and C
