-1 because x is 4 so you just plug it in and 4-8 is -4 and -4/4 is -1.
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: 9 people are left at the party
Step-by-step explanation:
There was originally 8 females and 12 males
8-2 = 6
Twice the males as females
9 men leave which leaves 3 men and 6 women which is twice as many men
Hope this helps!
6x^3+8x^2-10x-4 multiplied
Rate = 10/2 = 5 trees per hour
150trees/5 trees per hour = 30 hours
the answer is D = 30 hours
