The supply equation for an olive oil press is
vovangra [49]

Answer:

12 units

Step-by-step explanation:

The given function is

S(q) = 5q^2 + 1000q + 100

where, S(q) is the price in dollars at which q units are supplied.

We need to find the quantity supplied in a month when the company sets the price of its olive oil press at $12,820.

Substitute S(q)=12820 in the given function.

12820 = 5q^2 + 1000q + 100

Subtract both sides by 12820.

0= 5q^2 + 1000q - 12720

Taking out GCF.

0= 5(q^2 + 200q - 2544)

Now solve the equation for q by splitting the middle term.

0= 5(q^2 + 212q-12q - 2544)

0= 5(q(q + 212)-12(q + 212))

0= 5(q + 212)(q-12)

Using zero product property we get

q + 212=0\Rightarrow q=-212

q-12=0\Rightarrow q=12

q is number of units. So the value of q can not be negative.

Therefore the quantity supplied in a month when the company sets the price of its olive oil press at $12,820 is 12 units.

Write 2/3 as a decimal rounded to 3 sighificant figures
jasenka [17]

Answer:

0.667

Step-by-step explanation:

2/3= 0.66666

Dividing the given value to obtain the decimal value gives:

\frac{2}{3} =0.6666666666666667

The last number is 7 which is greater than 5 this will increment the previous number by 1.

As,the previous values are also '6', so this step will continue till three significant figures.

   0.666666666666667\\0.66666666666667\\0.6666666666667\\0.666666666667\\0.66666666667\\0.6666666667\\0.666666667\\0.66666667\\0.6666667\\0.666667\\0.66667\\0.6667\\0.667

             

So the value rounded up to 3 significant is 0.667

Greenfields is a mail order seed and plant business. The size of orders is uniformly distributed over the interval from $25 to $
LekaFEV [45]

Answer:

a) 47.55

b) 58

c) 47.88

Step-by-step explanation:

Given that the size of the orders is uniformly distributed over the interval

$25 ( a ) to $80 ( b )

<u>a) Determine the value for the first order size generated based on 0.41</u>

parameter for normal distribution is given as ;  a = 25,  b = 80

size/value of order  = a + random number ( b - a )

                                = 25 + 0.41 ( 80 - 25 )

                                =  47.55

<u>b) Value of the last order generated based on random number (0.6)</u>

= a + random number ( b - a )

= 25 + 0.6 ( 80 - 25 )

= 25 + 33 = 58

<u>c) Average order size </u>

= ∑ order 1 + order 2 + ----- + order 10  ) / 10

= (47.55 + ...... + 58 ) / 10

= 478.8 / 10 = 47.88
