Answer:

Probabilty of winning the next two matches in a row = 1/9

Step-by-step explanation:

The total number of possible outcome = 3

(Win, lose, draw)

The probability of obtaining a win in a single match = 1/3

The probability of winning in two rows is 1/3² = 1/9

The cost function in a computer manufacturing plant is C(x) = 0.28x^2-0.7x+1, where C(x) is the cost per hour in millions of dol
Licemer1 [7]

9514 1404 393

Answer:

  $562,500 per hour

Step-by-step explanation:

The cost will be a minimum where C'(x) = 0.

 C'(x) = 0.56x -0.7 = 0

  x = 0.7/0.56 = 1.25

The cost at that production point is ...

  C(1.25) = (0.28×1.25 -0.7)1.25 +1 = -0.35×1.25 +1 = 0.5625

The minimum production cost is $562,500 per hour for production of 1250 items per hour.

_____

<em>Additional comment</em>

This is different than the minimum cost <em>per item</em>. This level of production gives a per-item cost of $450. The minimum cost per item is $358.30 at a production level of 1890 per hour.

In a survey of college students, each of the following was found. Of these students, 355 owned a tablet, 292 owned a laptop, 280
avanturin [10]

Add all the numbers together to find the total amount of college students surveyed.

355 + 292 + 280 + 191 + 198 + 136 + 66 + 24 = 1,542

The number is already simplified considering it's a whole number. The answer is either 1,542 or 1,500

<em>(I say either because when it says to simplify I'm not sure if they want it to be rounded.)</em>

15) In your own words, write three or four sentences explaining what exponents are and how they are used in math
Scorpion4ik [409]

Answer:

Exponents

Step-by-step explanation:

exponents are basic short cut to write numbers like 100, 1000, 10000, 1000000 and so on.

Exponents can also be defined as 10 raised to a power x whether positive or negative

10 {}^{x}

They are mostly used in expressing units in standard form.

<h3>examples of basic positive exponents</h3>

{10}^{2}  = 100

10 {}^{3}  = 1000

{10}^{4}   = 10000

{10}^{5}  = 100000

basically the power represent the the number of zeroes after the 1.

<h3>examples of basic negative exponents</h3>

{10}^{ - 2}  = 0.01

{10}^{ - 3}  = 0.001

{10}^{ - 4}  = 0.0001

10 ^{ - 5}  = 0.00001

in negative exponents the power represents the number of zeroes before the 1. including the 0 behind the decimal point.

this is the basic lay down of how exponent work but one more quick example for maximum understanding

<h3>quick example</h3>

4 \times  {10}^{4}  = 0.0004

4 \times  {10}^{4}  = 40000

8.69 \times 10 {}^{ - 3}  = 0.00869

8.69 \times 10 {}^{  3}  = 8690

hope you grasp the concept involved in multiplication with other terms.

cheers
