Answer: 32760 ways.
Step-by-step explanation:
To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.
Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4
Number of ways to visit these 4 cities = 4!
Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways

Hope it helps :D
Hello there! Your answer would be 75/6 is larger than 12 1/6.
Need an Explanation?:
Divide 75 by 6 to start so we can equally look at the numbers.
75/6 = 12.5
We know that .5 is equal to 1/2, so change .5 to 1/2.
That means we now have 12 1/2.
So, which is larger: 12 1/6 or 12 1/2?
Obviously 12 1/2 is larger, so this is the one you should choose.

Answer:
x^3 -14x^2 -6
Step-by-step explanation:
Your expression is the difference of two polynomials. The parentheses can be removed by using the distributive property. The minus sign outside the second set of parentheses applies to each term inside parentheses.
-5x^2 +3 +x^3 -9x^2 -9
Now, you can group like terms. In "standard form", the degrees of the terms decrease from left to right.
x^3 +(-5x^2 -9x^2) +(3 -9)
And combine like terms.
x^3 -14x^2 -6 . . . . . simplified form of the given expression
110 x 1.73 = 190.3 rounded -> 190.30
Final answer: 190.30
