Answer:

$y = \frac{1 }{8} {(x + 3)}^{2}$

Step-by-step explanation:

$y = a(x - h)^{2} + k \\ y = a(x - ( - 3))^{2} + 0 \\ using \: points \: (1 ,\: 2) \\ 2 = a {(1 - ( - 3))}^{2} \\ 2 = a{4}^{2} \\ 16a = 2 \\ \boxed{ a = \frac{1}{8} } \\ hence \to \\ y = \frac{1}{8} (x - ( - 3))^{2} \\ y = \frac{{(x + 3)}^{2} }{8}$

Determine the missing number in the equation 13-2=12-?

soldier1979 [14.2K]

For the equation to work, you have to have the same number on both sides of the equal sign

so to find ?, you can do:

13 - 2 = 12 - ? Simplify

11 = 12 - ? Subtract 12 on both sides

-1 = - ? Multiply -1 on both sides

1 = ?

If there were 5 million births in a particular country and 3 comma 375 sets of naturally occurring triplets, what is the experi

IgorLugansk [536]

Answer:

$Probablity =P=6.75*10^-^4$

Step-by-step explanation:

The experimental probability can be defined as the ratio of the number of times any particular event has occurred to the total number of times that event has taken place.

Experimental probability = P = No. of event occurrences / total number of occurrences.

In our question statement,

No of naturally occurring triplets are = 3375

Total number of births = 5 million = 5,000,000

Putting values in equation.

$P=3375/5000000$
