There are 5 times as many males as females on the maths course at university. What fraction of the course are male? Give your an
Oksi-84 [34.3K]

Answer:

5/6

Step-by-step explanation:

Let 'x' be number of females in the course

Number of males= 5x

total number of students= 5x+x

                                         = 6x

Fraction of male students= number of male students/total number of students

                                         = 5x/6x

                                         = 5/6

A parabola y=1/2x^2-4x+21 can you help me find the vertex form of this parabola please and thank you :)
ale4655 [162]
Ok 
First factor out the first 2 terms as follows:-

y  = 1/2(x^2 - 8x) + 21

Now complete the square on x^2 - 8x:-

y = 1/2[ (x - 4)^2 - 16] + 21

y = 1/2(x - 4)^2 - 8 + 21

y = 1/2(x - 4)^2 + 13   Answer

It is an unfair coin with unknown probability of head and tail. Can you generate even odds using this coin?
Vladimir79 [104]

Answer:

Yes, it can be generated if p = \frac{n}{n+1}, where n is a positive even integer.

Step-by-step explanation:

An odds for an event, is the probability or chance that this event will occur, divided by the probability that it will not occur.

Assume that the probability of getting tail when throwing the coin is p, therefore, the probability of getting a head is (1-p) and the odds for the event of getting tail is \frac{p}{1-p}.

If k is a positive integer, and we assume that the odds of getting a tail are even, then:

\frac{p}{1-p} = 2k

p = 2k - 2kp

p = \frac{2k}{2k+1}

Conclusion: if p = \frac{2k}{2k+1}, for some positive integer k, even odds are generated. For example: p = 2/3, 4/5, 6/7, ...
