What is the anwere to this problem in the simple form

It is in simple form. There is absolutely nothing more that can be done, unless it is a joke. And math jokes are very hard to come by.

I don't think that y(y - 1)/(a + 2b) is any simpler.

Come to think of it, is that x^2 or y^2 on the top left.
I think my first answer is the best one. Nothing can be done.

How to solve a mixed fraction?

Hunter-Best [27]

To solve a mixed fraction you will have to multiply the mixed number by the denominator then add the numerator for example:
7 3/4 you are gonna go 7x4=28 then you are gonna take that 28 and add 3 to it so it would be 31. I hope that helped some c:

A worker at a landscape design center uses a machine to fill bags with potting soil. Assume that the quantity put in each bag fo

defon

Answer:

a) The expected value is given by:

$E(X) =\frac{a+b}{2}= \frac{10+12}{2}= 11$

The variance is given by:

$Var(X) = \frac{(b-a)^2}{12}= \frac{(12-10)^2}{12}= 0.3333$

And the standard deviation is just the square root of the variance and we got:

$Sd(x) = \sqrt{0.3333}= 0.5774$

b) $P(X$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a}, a \leq x \leq b$

And using this function we got:

$P(X$

c) $P(X>10.5)$

And using the complement rule and the cumulative distribution function we got:

$P(X>10.5)= 1-P(X$

Step-by-step explanation:

For this case we define the random variable X=quantity put in each bag , and we know that the distribution for X is given by:

$X \sim Unif (a= 10, b =12)$

Part a

The expected value is given by:

$E(X) =\frac{a+b}{2}= \frac{10+12}{2}= 11$

The variance is given by:

$Var(X) = \frac{(b-a)^2}{12}= \frac{(12-10)^2}{12}= 0.3333$

And the standard deviation is just the square root of the variance and we got:

$Sd(x) = \sqrt{0.3333}= 0.5774$

Part b

For this case we want this probability:

$P(X$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a}, a \leq x \leq b$

And using this function we got:

$P(X$

Part c

For this case we want this probability:

$P(X>10.5)$

And using the complement rule and the cumulative distribution function we got:

$P(X>10.5)= 1-P(X$

What value of x makes the

loris [4]

Answer:

$x = -12$

Step-by-step explanation:

<u>Step 1: Add 1/4x to both sides</u>

$-\frac{1}{4}x - 12 = x + 3$

$-12 - \frac{1}{4}x + \frac{1}{4}x = x + 3 + \frac{1}{4}x$

$-12 = \frac{5}{4}x + 3$

<u>Step 2: Subtract 3 from both sides</u>

$-12 - 3 = \frac{5}{4}x + 3 - 3$

$-15 = \frac{5}{4}x$

<u>Step 3: Multiply both sides by 4/5</u>

$-15*\frac{4}{5}=\frac{5}{4}x * \frac{4}{5}$

$-12 = x$

Answer: $x = -12$
