(b) What portion of the official U.S. poverty threshold (roughly $29,000 for a family of four) is met by the World Bank’s measur
otez555 [7]
World Bank's threshold for poverty is $1.25 per person per day. 
For a family of four this gives:
Daily income = (number of people) * threshold
Daily income = 4 * $1.25
Daily income = $5
For a year this is:
Yearly income = (daily income) *365
Yearly income = $5 *365
Yearly income = $1825

U.S. poverty threshold is set at $29000. Portion of threshold can be calculated as:
Portion\text{ }of\text{ }threshold= \frac{Poverty\text{ }threshold\text{ }(World\text{ }Bank)}{Poverty\text{ }threshold\text{ }(U.S.)} *100\% \\  \\ Portion\text{ }of\text{ }threshold= \frac{1825}{29000} *100\% \\  \\ Portion\text{ }of\text{ }threshold=6.29\%

The poverty threshold measured by World Bank is 6.29% of the U.S. poverty threshold.

Write the absolute value equation given the transformations
Evgesh-ka [11]

Answer:

<em>y = - 0.5 | x - 5 | + 2</em><em> </em>

Step-by-step explanation:

g(x) = |x|

1^{st} step - shifts right 5 units: g(x + 5) = | x <u><em>- 5</em></u> |

2^{nd} step - shifts up 2 units: g(x + 5) + 2 = | x - 5 | <u><em>+ 2</em></u>

3^{rd} step - reflected: - g(x + 5) + 2 =<em> - </em>| x - 5 | + 2

4^{th} step - stretched by 0.5: <em>y = - </em><u><em>0.5</em></u><em> | x - 5 | + 2</em>

<em>y = - 0.5 | x - 5 | + 2</em>
