If the average of three numbers is V if one number is Z and another is y what is the remaining number ?

Answers

The remaining number, using the concept of average, is $3V-y-z$

It is given that

Average of three numbers = V

One number = z

Another number = y

What is an average?

Average is the sum of observations divided by a number of observations.

Let us take the third number x

From the question

$(x+y+z)/(3) = V$

$x+y+z = 3V\n\nx=3V-y-z$

Therefore, the remaining number is $3V-y-z$

The formula for an average of three numbers is (x+y+z)/3. So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x. We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x

x = 3V - y - z

Answer:

$f^\prime(x)=-(x+1)^2-4$

Step-by-step explanation:

We have the function:

$f(x)=x^2$

And we want to write its equation after being: 1) Flipped over the x-axis, 2) shifted 4 units down, and 3) shifted 1 unit to the left.

To denote a flip over the x-axis, we multiply the function by -1. Hence:

$f^\prime(x)=-x^2$

Is our function flipped over the x-axis.

To shift n units vertically, we simply add n to our function.

Since we are going 4 units downwards, we will add -4 to our function. Hence:

$f^\prime(x)=-x^2-4$

Finally, to shift n units horizontally, we substitute our variable $x$ for $(x-n)$ .

Since we are shifting 1 unit to the left, n=-1. Hence, we will substitute $x$ for $(x+1)$ . Therefore:

$f^\prime(x)=-(x+1)^2-4$

So, our final function is:

$f^\prime(x)=-(x+1)^2-4$

A bag contains blue and yellow marbles. Two marbles are drawn without replacement. The probability of selecting a blue marble and then a yellow marble is 0.37, and the probability of selecting a blue marble on the first draw is 0.55. What is the probability of selecting a yellow marble on the second draw, if the first marble drawn was blue?
A) 18%
B) 20%
C) 46%
D) 67%

Answers

Let b = blue marbles
y = yellow marbles
Sum = b+y
The chance of a blue marble being drawn first is:
b / (b+y) = 0.55
The chance of a blue marble being drawn first then a yellow next is:
b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
