Answer: If you are looking for Slope-Intercept form (y=mx+b), It would be...
y=-5.4x+10840.4.
If you are looking for Point-Slope form, it would be...
y=-5.4x+10840.4.
Step-by-step explanation: Write in Slope-Intercept from, y=mx+b.
Point-Slope form : Use the Point-Slope formula, y-y1=m(x-x1) to find the equation of the line.
I hope this helps you out! ☺
$1.66 because 50-39.59=10.40 so it would also add $8.75 so that = $1.66
Answer:
The sample 2 has a lowest value of SE corresponding to the least sample variability.
Step-by-step explanation:
As the value of the sample means and standard deviations are not given, as similar question is found online from which the values of data is follows
The data is as attached with the solution. From this data
Sample 1 has a mean of 34 and a SE of 5
Sample 2 has a mean of 30 and a SE of 2
Sample 3 has a mean of 26 and a SE of 3
Sample 4 has a mean of 38 and a SE of 5
As per the measure of the sample variability is linked with the value of SE or standard error. Which is lowest in the case of sample 2 .
So the sample 2 has a lowest value of SE corresponding to the least sample variability.
Answer:
It will take nine years and four months for the refrigerator to pay for itself.
Step-by-step explanation:
The new refrigerator which costs $1200, saves the family 22% annually in energy cost.
Since the old refrigerator costs $580 to run, we want to determine how many years it will take for 22% of $580 per year to make $1200.
22% of $580
= 580 × 0.22
= 127.6
That is, it saved then $127.6 per year.
Now,
$1200/127.6
≈ 9.4
Which means, it will take 9 years and 4 months for the refrigerator to pay for itself.
