Answer:
See explanation below
Step-by-step explanation:
All the odd numbers can be written as 2n-1 where n is an integer.
The sum (S) of the first n positive odd numbers can be written as:
If we change the order to a decreasing order we would write it this way:
Let's sum up both equations, we are going to pair the first number of our first equation with the first number of our second equation, we can see that each pair sums up 2n ( let's see this: (2n-1 + 1 =2n, 2n-3 + 3 = 2n, 2n-5 + 5 = 2n...)) therefore we would get n pairs that sum up 2n.
Therefore, the sum of the first n positive odd numbers is square.
Answer:
The probability density function of <em>X</em> is:
Step-by-step explanation:
A continuous Uniform distribution is the probability distribution of a random outcome of an experiment that lies with certain specific bounds.
Consider that random variable <em>X</em> follows a continuous Uniform distribution and the value of <em>X</em> lies between <em>a</em> and <em>b</em>.
The probability density function of the random variable <em>X</em> is:
Now, in this case it is provided that the amount of salad taken is uniformly distributed between 5 ounces and 15 ounces.
The random variable <em>X</em> is defined as:
<em>Χ</em> = Salad plate filling weight.
The probability density function of the salad plate filling weight is:
The correct answer would be ‘B’ because...
A rounds up to 277000
B rounds to 276000
C rounds to 275000
And D rounds to 275000 as well.
