PLSSS HELP!! For the given ordered pairs, write a function rule relating x and y. (1,4), (2,9), (3,16), (4,25)

LenKa [72]

Answer:

y=(x+1)^2

Step-by-step explanation:

we have the following

$x=1;y=4\\\\x=2;y=9\\\\x=3;y=16\\\\x=4;y=25$

the values of y are squares so we can write

$x=1;y=2^{2} \\\\x=2;y=3^2\\\\x=3;y=4^2\\\\x=4;y=5^2$

so as you can see when

$x=n;y=(n+1)^2$

so our relation is

$y=(x+1)^2$

One person is selected at random from a class of 20 males and 13 females. Find the odds against selecting a male and a female

spin [16.1K]

Answer:

Odds for male= 1.538

Odds for female = 0.65

Step-by-step explanation:

The question is asking for odds, not a probability. A probability shows how much the chance for the event to happen, so it can be expressed as a percentage. Odds show how the event more likely to happen compared to the chance it did not happen. If an event has a 90% probability, the odds will be 90:10= 9

In this case, the odds of selecting a male will be:

number of male : number of female= 20:13 = 1.538

The odds of selecting a female will be

number of female : number of male = 13/20 = 0.65
