6 0

Answer:

New amount (decrease) = £17253.53

Step-by-step explanation:

<u>Given the following data;</u>

Amount = £19064.67

Percentage = 9.5%

To find the percentage decrease;

Percentage \; cost = \frac {9.5}{100} * 19064.67

Percentage \; cost = 0.095 * 19064.67

Percentage cost = £1811.14

New amount (decrease) = Original amount - percentage cost

Substituting into the equation, we have;

New amount (decrease) = £19064.67 - £1811.14

<em>New amount (decrease) = £17253.53</em>

melomori [17]

Answer:

There are 436937109262510348800 ways to selected 12 countries.

Step-by-step explanation:

Let x_1, x_2, x_3, x_4,x_5 the countries selected from the block of 45. For x_1 there are 45 options of countries to select. For x_2 there are 44 options of countries to select because there can be no repeated countries. With the same reasoning, for x_3 there are 43 options, for x_4 there are 42 options and for x_5 there are 41 options.

Let x_6, x_7, x_8, x_9 the countries selected from the block of 57 countries. For x_6 there are 57 options of countries to select. For x_7 there are 56 options of countries to select because there can be no repeated countries. With the same reasoning, for x_8 there are 55 options and for x_9 there are 54 options.

Let x_{10}, x_{11}, x_{12} the countries selected from the block of 69 remain countries. For x_{10} there are 69 options of countries to select. For x_{11} there are 68 options of countries to select because there can be no repeated countries and for x_{12} there are 67 options.

For find the total of options o ways to select 12 countries we multiply the above options.

45*44*43*42*41*57*56*55*54*69*68*67= 436937109262510348800
