We have to find the probability N(11,2)>12, wherein N(11,2)
is the normal law with mean 11 and standard deviation 2.
Using a scientific calculator we get the probability 0.3.
Now multiply by the population which is 1000 like this:
0.3*1000=300.
There is 300 <span>spiders in the colony which weigh more than 12 grams</span>
600 becuase 90/.30= 300 and 300*2 =600
Answer:
0.48
Step-by-step explanation:
1x3/56 then multiply it by 9
1x3 is 3
3 x 9 = 27
27/56 this fraction cant be reduced so if you count it or put it in a calculator you'll get 0.482143
Answer:
48 inches
Step-by-step explanation:
Solving this requires use of conversions
we already know that
2.05 m > 2 m
all that's left is the question
200 cm vs. 2.05 meters
I we know our equivalencies, we know that
100 cm = 1 m
if this is so then
200 cm = 2 m
we already know that
2.05 m > 2 m
so it must also be that
2.05 m > 200 cm
