Number of chocolate cookies is 12 cookies

Number of other cookies is 6 cookies

<h3>Further explanation</h3>

Order of Operations in Mathematics follow this following rule :

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem !

<u>Given:</u>

<em>Out of 18 cookies, 2/3 are chocolate chip.</em>

<em>The above statement can be written in a mathematical equation as follows:</em>

$\texttt{Number of Chocolate Cookies} = \frac{2}{3} \times \texttt{Total number of Cookies}$

$\texttt{Number of Chocolate Cookies} = \frac{2}{3} \times 18$

$\texttt{Number of Chocolate Cookies} = 2 \times 6$

$\texttt{Number of Chocolate Cookies} = 12 ~ \texttt{cookies}$

<h2>Conclusion :</h2>

$\texttt{Number of Chocolate Cookies} = 12 ~ \texttt{cookies}$

$\texttt{Number of Other Cookies} = (18 - 12) = 6 ~ \texttt{cookies}$

A distribution of probabilities for random outcomes of bivariate or dichotomous random variables is called (A) binomial probability distribution.

<h3>What is a binomial probability distribution?</h3>

The binomial distribution with parameters n and p in probability theory and statistics is the discrete probability distribution of the number of successes in a succession of n separate experiments, each asking a yes-no question and each with its own Boolean-valued outcome: success or failure.

The binomial distribution is widely used to describe the number of successes in a sample of size n selected from a population of size N with replacement.
If the sampling is done without replacement, the draws are not independent, and the resulting distribution is hypergeometric rather than binomial.
Binomial probability distribution refers to a distribution of probabilities for random outcomes of bivariate or dichotomous random variables.

As the description itself says, binomial probability distribution refers to a distribution of probabilities for random outcomes of bivariate or dichotomous random variables.

Therefore, a distribution of probabilities for random outcomes of bivariate or dichotomous random variables is called (A) binomial probability distribution.

The graph of y=ax^2+bx+c passes through points (0,5), (1,10), and (2,19). Find a+b+c.

nataly862011 [7]

Answer: a = 2 b = 3 c = 5

Literally a+ b+c = 10, but I don't think that's what the question means to ask.

the equation is 2x² +3x + 5

Step-by-step explanation: Substitute the values of the given coordinates into the formula and use algebra (solve a system of equations by substitution and elimination) to get the values of a,b & c

y=ax²+bx+c using (0,5), (1,10), and (2,19)

5=a(0)²+b(0)+c becomes 5= 0+0 + c .so we find c = 5

10=a(1)²+b(1)+c becomes 10 = a + b + c

19=a(2)²+b(2)+c . becomes 19 = 4a + 2b + c

Substitute the 5 for c. Then rewrite

10 = a + b + 5 becomes 5 = a+ b to eliminate b multiply this be (-2)

(-2)( 5 = a+ b) .to get -10 = -2a - 2b

19 = 4a + 2b + 5 becomes 14 = 4a + 2b

_______________ Add these two

14 = 4a + 2b

<u>-10 = -2a - 2b</u><u> </u> this will eliminate the "b" term

4 = 2a divide both sides by 2 so you have a = 2

substitute in 10=a(1)²+b(1)+5 to find b

10=2(1)²+b(1)+5 .becomes 5 = 2 + b Subtract 2 from both sides

b = 3

So now you have all three values:

a = 2 b= 3 c = 5

I am attaching the graph. I hope this deserves Brainiest.

Best wishes in your studies!
