7 0

Answer:

(a) 0.018 dm^3

(b) 20 x 10^15 ml^3

Step-by-step explanation:

a) 18 cm^3 to dm^3

1 cm = 0.1 dm

So,

1 cm^3 = 0.001 dm^3

So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3

b) 20 hl^3 to ml^3

1 hl = 100000 ml

So, 1 hl^3 = 10^15 ml^3

So,

20  hl^3 = 20 x 10^15 ml^3.

(-5/6x+51/2)-(2/3x+4)
stiv31 [10]

Answer:

-1.5x + 21.5 (or (43-3x)/2)

Step-by-step explanation:

(-5/6x + 51/2) - (2/3x + 4)

<em>First, find the opposite of 2/3x + 4 because of the negative sign.</em>

-5/6x + 51/2 - 4/6x - 4

<em>Now combine -5/6x and -4/6x to get -9/6x or -3/2x</em>

-3/2x + 51/2 - 4

<em>Convert 4 into 8/2 since 51/2 is a fraction.</em>

-3/2x + 51/2 - 8/2

<em>Since the denominators of 51/2 and -8/2 are the same, just subtract 51 and 8 to get 43.</em>

-3/2x + 43/2

<em>-3/2x and 43/2 have the same denominator (2), so you can just put it like this (It's up to you!):</em>

(43-3x)/2

The answer to (-5/6 + 51/2) - (2/3x + 4) is -3/2x + 43/2 (or (43-3x)/2)

<em>Or you could put it like this (I converted both -3/2 and 43/2 to a decimal.)</em>

-1.5x + 21.5

Among the contestants in a competition are 46 women and 23 men. If 5 winners are randomly selected, what is the probability that
eimsori [14]

Answer:

When 5 winners are randomly selected, the probability that they are all men is 0.003.

Step-by-step explanation:

Among the contestants in a competition are 46 women and 23 men.

Total persons are =46+23=69

When one winner is chosen, there are 68 people left, when second winner is chosen there are 67 people left and so on.

So, the probability that they are all men is given by:

\frac{23}{69} \times\frac{22}{68} \times\frac{21}{67} \times\frac{20}{66} \times\frac{19}{65}

= \frac{4037880}{1348621560} = 0.002999 ≈ 0.003

Therefore, when 5 winners are randomly selected, the probability that they are all men is 0.003.
