6 runners, 3 medals, how many ways to give them? well, runner say 2 could get gold or not, bronze or not and silver or not, and so can any other runnner, and the order "does matter", it makes a distinction, thus, is a Permutation
Answer:
I think 47 and 55
Explanation:
I think that each number is the previous one plus 8;
7+8=15
15+8=23
23+8=31
31+8=39
So, next will be:
39+8=47
47+8=55
Is this what ur looking for?? hope this help:)
Its fairly straightforward. Since the bottom equation only has one unknown,x, because y=1.3, you can plug y in and solve for x. Once you find the value of x, you then have the value for two variables, x and y, and again have one unknown coefficient a. To solve for the coefficient you just plug in your y value (1.3) and your x value (which can be rounded to 0.42). Using a little bit of algebra, you can then solve for a which should be a=2.108. I am not sure if your teacher wants you to solve it this way but you could also use the elimination method or substitution method that you would of learned when discussing system of equations. But no matter which way you do it, the math follows the rules. Hope this helps. I’d suggest you solve it yourself to double check my work.

Answer:

Step-by-step explanation:
Because
is being multiplied by S, we can divide
from both sides of the equation. This will give us:
÷
But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of
÷
, you get:
×
When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.
By doing that, you get the fraction 
cannot be simplified any more, so S=
is your answer :)
I hope this helps

The probability of winning the lottery is 
</h3>
Step-by-step explanation:
Here, the total numbers in the jackpot = 1 to 34
Now, the number that needed to be drawn = 5
The number of ways , 5 number can be drawn from total 34 numbers :

Also, in separate draw, the correct number drawn = 1
So, the number of ways that can be done = 30 C 5 x 37
= 278,256 x 37 = 10,295,472
Now, P(win) = 
Hence, the probability of winning the lottery is
