Answer:
25
Step-by-step explanation:
2400 dived by 96 is 25
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:
15 feet
Step-by-step explanation:
It is given that Quadrilateral ABCD is similar to Quadrilateral EFGH. This means that the corresponding sides of these two quadrilateral will be in the same proportion.
i.e.
Ratio of two corresponding sides would be the same. We are given longest three sides of ABCD and shortest two sides of EFGH. Let the 4th sides of ABCD i.e. the shortest side be x.
So, the ratio of the shortest sides of two quadrilaterals would be the same as the ratio of second shortest sides.
So,

So, the 4th side on quadrilateral ABCD would be 15 feet. None of the options match with the answer.
Answer with Step-by-step explanation:
We are given that if sum of several numbers is odd
We have to prove that at least one of the number is itself odd.
Suppose, we have three numbers
a=6 , b=7,d=8
Sum of numbers=6+7+8=21=Odd number
We know that sum of two odd numbers is always an even number.
Sum of an odd number and an even number is always an odd number.
If we take even odd numbers then sum is always an even number and sum of odd odd numbers then the sum is always an odd number.


Sum of even numbers is always an even number.
Hence, there are atleast one numebr is odd then the sum of several number is odd.
