1 volunteer - 4 h - 48 calls
12 volunteers - 4 h - x calls

The time is the same, so it's irrelevant.
1 volunteer - 48 calls
12 volunteers - x calls

x=12*48=576

So it's 576 hours.

A coin is weighted so that the probability of getting heads is 0.70. If the coin is flipped twice, what is the probability of ge
Naily [24]
If the probability of flipping heads is 0.70, the probability of flipping tails is 0.30. 

To find probability, you multiply the probability of each factor together:

P = 0.7  * 0.3 

P = 0.21 <em>or</em>
<em> </em>21%

Find the set of outcomes that occur when we flip 3 coins and obtain at least two tails.
Vikentia [17]
First, I would show all the outcomes possible. To determine the number of the total outcomes, you use the formula: rⁿ, where r is the number of outcomes in 1 flip, and n is the number of lips. Thus, 2³ = 8 outcomes. These outcomes are:

1. HHH
2. TTT
3. HHT
<em>4. HTT</em>
5. HTH
6. THH
<em>7. TTH</em>
<em>8. THT</em>

From the given outcomes, there are <em>3 outcomes</em> that has at least two tails. These are the ones in bold characters.

You just want to simplify right?!

45. (a^2b^3)(ab)^-2
= (a^2b^3)(a^-2b^-2)
= b
46. (-3x^3y)^2(4xy^2)
= (-9x^6y^2)(4xy^2)
= -36x^7y^4
47. 3c^2d(2c^3d^5) / 15c^4d^2
= 6c^5d^6 / 15c^4d^2
= 2/5c1/4x^4
48. -10g^6h^9(g^2h^3) / 30g^3h^3
= -10g^8h^12 / 30g^3h^3
= -1/3g^5h^9
49. 5x^4y^2(2x^5y^6) / 20x^3y^5
= 10x^9y^8 / 20x^3y^5
= 1/2x^6 1/3y^3
50. -12n^7p^5(n^2p^4) / 36n^6p^7
= -12n^9p^9 / 36n^6p^7
= -1/3n^3p^2

(Sorry it’s messy it’d look better if my phone could actually put the numbers to the power)
