Mathematics
1 answer:
Feliz [49]3 years ago
6 0

Answer:

Step-by-step explanation:

consider 6x^2-8x +k

disc .=(-8)^2-4*6*k=64-24k

it has no solution if 64-2k<0

or 64<2k

or 2k>64

k>32

it has two zeros if 64-2k≥0

or 64≥ 2k

or 2k≤64

or k≤ 32

it has one zero if Disc. =0

64-2k=0

2k=64

k=32

Ephemeral services corporation (esco) knows that nine other companies besides esco are bidding for a $900,000 government contrac
EastWind [94]

Answer:

c. $100,000

Step-by-step explanation:

Calculation of the expected net profit of Ephemeral services corporation

Since we are been told that 9 other companies besides esco are as well bidding for the $900,000 government contract, it means we have to find the expected net profit by dividing 1 by 9×$900,000 .Thus ESCO can only expect to cover its sunk cost.

Hence ,

E(X) = (1/9) × $900,000

E(X)=0.111111111×$900,000

E(X)= $100,000

Therefore the expected net profit would be $100,000

Answer:

  • (3y)(2x^2 -1x -8xy +4y)
  • (3y)(x -4y)(2x -1)

Step-by-step explanation:

<u>Part A</u>: All of the coefficients have a common factor of 3. All of the variable products have a common factor of y, so the greatest common factor of all terms is 3y. The expression can be written as ...

  (3y)(2x^2 -1x -8xy +4y)

__

<u>Part B</u>: The remaining factor can be factored pairwise:

  3y(x(2x -1) -4y(2x -1)) = 3y(x -4y)(2x -1)

True or False. To select 3 items out of 4 distinct objects, use C(4,3).
kenny6666 [7]

Answer:

True.

Step-by-step explanation:

C(4, 3) means the number of combinations from 4 items taking 3 at a time.  We are selecting 3 distinct items and it doesn't say anything about the order in which they are selected , so we use  a combination formula  not a permutation ( where order does matter).

C(4, 3)  = 4! / 3! 1!

= 4*3*2*1 / 3*2*1*1

= 4.

There are 4 ways to select 3 items from 4.
