No solution

to eliminate a variable you need to multiple the second equation by either a 3 and then subtract the two equations or by a -3 and add the two equations.
after changing it, instead of eliminating only one variable, both variables are eliminated and there is no solution

i hope this makes sense, not sure how else to explain

The answer is 20 if the “18-2” is in the square root
If it’s square root of 18 and then minus 2
The answer is 15 square root 2 minus 2

Answer:

$5P3*6C4=60*15=900$

Step-by-step explanation:

$5P3$ refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;

$5P3=\frac{5!}{(5-3)!}$

The factorial of an integer n is evaluated as;

$n!=n*(n-1)*(n-2)*(n-3).......3*2*1$

Using this concept, the above expression can now be simplified as follows;

$5P3=\frac{5!}{2!}=\frac{5*4*3*2!}{2!}=5*4*3=60$

Therefore, the permutations of 5 items taken 3 at a time is 60.

The next expression, $6C4$ refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;

$6C4=\frac{6!}{4!(6-4)!}=\frac{6!}{4!*2!}=\frac{6*5*4!}{4!*2*1}=\frac{6*5}{2*1}=15$

Therefore, the combinations of 6 items taken 4 at a time is 15.

The final step is to evaluate the product;

$5P3*6C4=60*15=900$

A bag contains 4 blue balls, 7 yellow balls and 4 white balls. Event A is defined as drawing a blue ball on the first draw and e

P(B|A) expressed in simplest form is 8/105.

<h3>What is the probability?</h3>

Probability determines the chances that an event would happen. The chance of the event happening lies between 0 and 1.

P(B|A) = (number of blue balls / total number of balls) x (number of white balls / total number of balls - 1 )

(4/15) x 4/14 = 8/105
