Determine the standard deviation (SD)
The standard deviation of a binomial distribution is calculated as thus:
Substitute values for n and p
Convert to decimals
--- <em>approximated</em>
<em>Hence, the calculated standard deviation is approximately 8.4932</em>
This is not as hard as it seems. All shapes will follow ratios when they undergo a change in overall size. The first part is finding the size of line G-A. Since we know perimiter, we can simply subtract the other sides from the total permitier. This gives us that GA is 30. Since the ratio of
=
, we can simply do 14/35 = x/30. Sp x = 30*14/35 =12
What is the rest of the question?
Answer:
0.06
Step-by-step explanation:
ok 1 tenth and 1 sixth are our equasions so lets conver then to desimals and lets start with 1 tenth so we devide 1/10 is 0.1 and now for 1 sixth is 0.6 so now we multiply the two and get 0.06
Make two equations representing the position of each animal, p and k, for the puppy and kitten respectively.
p=25t and k=180+20t
The puppy will catch the kitten when p=k so we can say:
25t=180+20t subtract 20t from both sides
5t=180 divide both sides by 5
t=36
So the puppy will catch the kitten after 36 seconds.
