The total cost for a production process is equal to $1,000 plus two times the number of units produced. The mean and variance fo

Andrej [43]

Answer:

$\mu_p=2000\\\\\sigma_p^2=3600$

Step-by-step explanation:

Let X be the number of units produced, and P be the cost of production.

#Given that $\mu_x=500, \sigma_x^2=900$

Cost of production can be calculated as:

$P=1000+2X$

#Mean of the total cost is calculated as;

$\mu_p=1000+2\mu_x\\\\=1000+2(500)\\\\=2000$

Hence, the mean cost of production is $2,000

#Variance of the total cost is calculated as;

$\sigma_p^2=2^2\sigma_x^2\\\\=2^\times 900\\\\=3600$

Hence, the variancecost of production is $3,600

Where do (3/2,-7) and (-4,5) intercept

Vinil7 [7]

Answer:

The intercept of the given points is - $\frac{41}{11}$

Step-by-step explanation:

Given points as :

( $x_1$ , $y_1$ ) = ( $\frac{3}{2}$ , - 7 )

( $x_2$ , $y_2$ ) = ( - 4 , 5 )

Now, slope of line using given points can be written as :

Slope = m = $\dfrac{y_2 - y_1}{x_2 - x_1}$

or. m = $\dfrac{5 - ( - 7 )}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\dfrac{12}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\frac{12}{\frac{- 8 - 3}{2}}$

Or, m = $\frac{12}{\frac{- 11}{2}}$

∴ m = $\frac{-24}{11}$

So, The slope of the line using points = m = $\frac{-24}{11}$

now, equation of line in slope intercept form can be written as

y - $y_2$ = m × ( x - $x_2$ )

or, y - 5 = $\frac{-24}{11}$ × ( x - ( - 4 ) )

or, y - 5 = $\frac{-24}{11}$ × ( x + 4 )

Or, 11 × ( y - 5 ) = - 24 × ( x + 4 )

Or, 11 y - 55 = - 24 x - 96

Or, 11 y = - 24 x - 96 + 55

Or, 11 y = - 24 x - 41

∴ y = $\frac{-24}{11}$ x - $\frac{41}{11}$

Now, comparing with slope intercept equation

I.e y = m x + c , where c is the intercept

So, The intercept of points is - $\frac{41}{11}$

Hence The intercept of the given points is - $\frac{41}{11}$ Answer

Answer: A

Step-by-step explanation:

when thinking about the figurative language we understand that you have to dig deeper for the answer just like poems lol, but the answer is A because when he says they are beating it with a hose to find out what it truly means it makes sense to criticize the way some readers try and understand poems. plus i got it right on the test kisses :)

if you want please mark me brain list :))))))

An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it f

alina1380 [7]

The end of its travel is when S(t)=0 or when it has hit the ground...

-16t^2+25=0 divide equation by -1

16t^2-25, this is a difference of squares which always factors:

(a^2+b^2)=(a+b)(a-b), in this case:

(4t+5)(4t-5)=0, since t>0

t=5/4=1.25, and since it started falling at t=0, its time moving in the air is:

1.25-0=1.25 seconds.
