Tina must select and answer in any order three of seven

Leno4ka [110]

Answer:

Tina can select and answer the essay questions on her test in 35 ways.

Step-by-step explanation:

The order in which she chooses the questions is not important. For example, choosing questions 1, 3 and 7 is the same as choosing 7, 3 and 1. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Three questions from a set of 7. So

$C_{7,3} = \frac{7!}{3!(7-4)!} = 35$

Tina can select and answer the essay questions on her test in 35 ways.

I'm not sure how to do this

valentinak56 [21]

Well for 11, it is an inequality, a > sign or < sign with a little underscore mean either "greater than or equal to" or "less then or equal to" so 30> 12+m (>with an underscore) means 30 is greater than or equal to 12+m

Simplify the rational expressions. State any excluded values. Show your work. (3x - 6)/(x - 2)

cluponka [151]

Hello,

Put the 3 as a common factor.

Look:

3x - 6 = 3 . ( x - 2 )

Then,

( 3x - 6) / (x - 2) = 3 .( x - 2) / (x -2)

Now simplity ( x -2)

= 3
