10a+3+2a=39
First simplify
12a+3=39
Then subtract 3 from both sides
12a=36
Then divide both sides by 12
a=3

10a+3+2a=39
12a+3=39
-3 -3
12a=36
/12 /12

Thank you for posting your question here at brainly. The quadratic function that models the data as a function of x, the number of weeks is the second one which is "P(x) = 13x2 – 10x + 350; 1,102 fish". I hope the answer will help you.

Question 6

babunello [35]

Answer:

$P(X=3)$

And using the probability mass function we got:

$P(X=3)= (12C3)(\frac{1}{6})^3 (1-\frac{1}{6})^{12-3}=0.1974$

Step-by-step explanation:

Let X the random variable of interest "number of times that 6 appears", on this case we now that:

$X \sim Binom(n=12, p=1/6)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X=3)$

And using the probability mass function we got:

$P(X=3)= (12C3)(\frac{1}{6})^3 (1-\frac{1}{6})^{12-3}=0.1974$
