I'm not sure which one is the scale size so i'll solve for both...
Ratio is 2cm:4m
0.02m:4m or 2cm:400cm also work as ratios
400cm/2cm=200 (so the scale is 200X smaller than the original)
Option 1::
If the scale of the item is:
l=12cm and w=6cm
then we can solve for the actual size by multiplying the values by 200
l=12cm*200=2400cm or 24m
w=6cm*200=1200cm or 12m
Option 2::
If the original item has a length of 12m and a width of 6m then:
l=12m and w=6m
We can find the scale length by dividing by 200
l=12m/200=.06m or 6cm
w=6m/200=0.03m or 3cm
Answer:
This is cluster sampling.
Step-by-step explanation:
American Airlines randomly selects 110 flights during a certain week and surveys all passengers on the flights.
This is a type of cluster sampling.
This type of sampling is done by dividing the population into different groups and a simple random sample of clusters is selected from the population.
Step-by-step explanation:
4325 * 32 = 138,400
5492 * 44 = 241,648
I have provided work to show how you would complete these problems. The work will be found in the attachments below.
Answer:
10 5 40
Step-by-step explanation:
if it is a sample and there are 5 diffrant things that is supposed to be in there, the 5 would be just rediculus, if it is 10, that would make more sense. 40, that would be more like the regular versian of it
hope this helps!!!
Complementary angles sum to 90°. Supplementary angles sum to 180°.
