<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>

P(M) = number of students who plan to major in mathematics / number of students

P(M) = 80 / 200 = 0.4

????????????????????????????????????

artcher [175]

Answer:

3x-5y

Step-by-step explanation:

All you need to do here is combine like terms.

13x - 10x = 3x

2y - 7y = -5y

When they ask you to simplify the expression, they're not looking for you to solve anything. You just have to combine what you can. :)

U.S. craft-beer breweries (breweries that make fewer than 6 million barrels annually and are less than 25% owned by big brewerie

yarga [219]

Answer:

(a) a = 43.25 , b = 41 and c = 1547

(b) The number of craft-beer breweries in 2016 = 4643

Step-by-step explanation:

Given that the number of small craft-beer breweries from 2008 to 2012 is modeled by using a quadratic function of the form f(t) = at² + bt + c where a, b, and c are constants and t is measured in years, with t = 0 corresponding to 2008.

(a) Now we have to find these constants given f(0) = 1547, f(2) = 1802, and f(4) = 2403.

So, <em>f(0) = </em> $a*(0)^{2} + b*(0) + c$ <em> which implies that </em><em>c = 1547</em><em>.</em>

<em>f(2) = </em> $a*(2)^{2} + b*(2) + c$ <em> = 4a + 2b + c</em>

4a + 2b + c = 1802 ----------- [Equation 1]

<em>f(4) = </em> $a*(4)^{2} + b*(4) + c$ <em> = 16a + 4b + c </em>

16a + 4b + c = 2403 ----------- [Equation 2]

Further solving Equation 1 we get; 4a + 2b + 1547 = 1802

4a + 2b = 1802 - 1547 ; 4a + 2b = 255 ----------- [Equation 3]

Further solving Equation 2 we get; 16a + 4b + 1547 = 2403

16a + 4b = 2403 - 1547 ; 16a + 4b = 856 ----------- [Equation 4]

Now, Solving Equation 3 and 4 we get ;

a = 43.25 and b = 41 .

Therefore, values of constants a, b and c are 43.25, 41 and 1547 respectively.

(b) So, model we obtained in part (a) is represented as :

f(t) = $43.25t^{2} + 41t + 1547$

Now to estimate the number of craft-beer breweries in 2016, assuming that the trend continued we know that t would be 8 as 2016 - 2008 = 8 years.

<em>So, f(8) = </em> $43.25*(8)^{2} + 41*8 + 1547$ <em> = 4643.</em>
