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>
Answer:
12 with the exponent of 6 becuz 12 is bigger than 8
Answer:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
Step-by-step explanation:
We know that the dive results in 40 gold coins.
We know that:
Alice: $7,600 Ben: $5,900 Carlos: $1,400.
So they have $ 14900 in total.
Now we will divide that money by 40.
So 1 gold coin costs $ 372.5. Now we will calculate how much they can get for the money they have.
We conclude that:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
