This is a sampling technique used when natural groupings are evident in a statistical population. It is often used in marketing research.
Machine K y= 26x
y = 26 (11)
y = 286 candies in 11 minutes from Machine K
Machine J
90 / 3 = 30 candies a minute * 11 minutes = 330 candies
330 - 286 = 44
Machine J can pack 44 more candies than Machine K in 11 minutes.
Last week, Christopher drove 480 miles
This week, Christopher drove 360 miles
The difference in miles this week compared to last week = 480 - 360 = 120 miles.
The percentage of decrease in miles compared to last week's = (Difference in miles ÷ Total miles last week) multiplied by 100 = (120 ÷ 480) x 100 = 0.25 x 100 = 25%
Answer:

Now since we have the same units for the scale model and the real one we can find the scale factor like this:

And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
Step-by-step explanation:
For this problem we know that the scale model had a widthof 6 inches. And the actual model has a width of 4ft. First we need to convert the 4ft to inches and we got:

Now since we have the same units for the scale model and the real one we can find the scale factor like this:

And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
