$\bold{Answer}$

$\boxed{\bold{-20x^6+12x^4-4x^3+8x^2}}$

$\bold{Explanation}$

$\bold{Simplify: \ -4x^2\left(5x^4-3x^2+x-2\right)}$

$\bold{------------------}$

$\bold{Distribute \ Parenthesis}$

$\bold{\left(-4x^2\right)\cdot \:5x^4+\left(-4x^2\right)\left(-3x^2\right)+\left(-4x^2\right)x+\left(-4x^2\right)\left(-2\right)}$

$\bold{Apply \ Addition \ / \ Subtraction \ Rules: \ +\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab}$

$\bold{-4\cdot \:5x^4x^2+4\cdot \:3x^2x^2-4x^2x+4\cdot \:2x^2}$

$\bold{Simplify \ -4\cdot \:5x^4x^2+4\cdot \:3x^2x^2-4x^2x+4\cdot \:2x^2: \ -20x^6+12x^4-4x^3+8x^2}$

$\bold{-20x^6+12x^4-4x^3+8x^2}$

$\boxed{\bold{Eclipsed}}$

The monthly sales of Sunny Electronics' new sound system are given by q(t)=4000t−100t² units per month, t months after its intro

zysi [14]

Answer:

The rate of change with respect to monthly sales is 4000 - 200t.

Step-by-step explanation:

The sales per month (monthly sales) of the new sound system being sold by Sunny Electronics is given by q(t) = 4000t - 100 $t^2$ units per month, where t is number of months from the introduction of the sound system.

The price of each unit of the sound system charged by Sunny Electronics is given by p(t) = 2000 - $t^2$ .

The rate of change with respect to monthly sales will be given by the equation

$\frac{dq(t)}{dt} = \frac{d(4000t - 100t^2)}{dt} = 4000 - 200t$ .

Does it pay to ask for a raise? A national survey of heads of households showed the percentage of those who asked for a raise an

zvonat [6]

Answer:

Cross probability

Step-by-step explanation:

The type of probabilities remains to be determined. That is the question itself. The same problem is found in the book "Understanding basic statistics 7th edition of Brase".

I will assume that the three probabilities to find are:

a) p (woman asked for a raise)

b) p (received raise | asked for one)

c) p (received raise and asked for one)

So,

a) p(woman asked for a raise)

It is given in the statement, so it is simple statistics:

$P_{WomA} =25%$

b) p(received raise | asked for one)

It is also found in the statement, however, now the formula would be given by:

p(received raise | asked for one) = p(received raise and asked for one) / p(asked for one)

$P_{WomB}=46%$

c) p(received raise and asked for one)

For this case the formula is given differently and it is necessary to re-adjust formula B, as follows:

p(received raise and asked for one) = p(received raise | asked for one) * p(asked for one)

So,

$P_{WomC} = 0.46*0.25 = 11.5%$

p(received raise and asked for one) = 11.5%
