A marble is drawn at random from a bag containing 2 blue marbles, 3 yellow marbles, and 7 orange marbles. What is the probabilit

total marbles: 2+3+7 = 12

add blue and yellow 2+3=5

7 marbles aren't blue or yellow

probability = 7/12 marble is not one of those

Suppose line segment AB has one endpoint at A(0, 0). What are the coordinates of B if (5, 3) is 1/3 of the way from A to B?

Bumek [7]

Given:

Line segment AB has one endpoint at A(0,0).

(5, 3) is 1/3 of the way from A to B.

To find:

The coordinates of point B.

Solution:

Let the coordinates of point B are (a,b).

Suppose point P(5, 3) is 1/3 of the way from A to B.

$\dfrac{AP}{AB}=\dfrac{1}{3}$

$\dfrac{AP}{PB}=\dfrac{AP}{AB-AP}=\dfrac{1}{3-1}=\dfrac{1}{2}$

It means, point P(5, 3) divides the segment AB in 1:2.

Section formula:

If a point divides a line segment in m:n, then

$Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)$

Point P(5, 3) divides the segment AB in 1:2. Using section formula, we get

$P=\left(\dfrac{1(a)+2(0)}{1+2},\dfrac{1(b)+2(0)}{1+2}\right)$

$(5, 3)=\left(\dfrac{a}{3},\dfrac{b}{3}\right)$

On comparing both sides, we get

$\dfrac{a}{3}=5$

$a=15$

$\dfrac{b}{3}=3$

$b=9$

Therefore, the coordinates of point B are (15,9).

Ryan is conducting an observational study on human behavior in different environments. Which of these sample sizes will probably

Tanya [424]

This is the case of Inductive Arguments. In logic, inductive arguments are all about the content of the premises and involve probability. Logicians focus on the strength of this type of argument. In a strong inductive argument, if the premises are assumed true, it is likely<span> that the conclusion is true, it does not mean that it must be true, it is possible that the conclusion could be false. Thus, if the conclusion is likely to not be true based on the assumed truth of the premises, the inductive argument is weak.

</span><span>While there are mathematical ways to determine probability, most of the time you'll have to use your intuition and experience to help you figure out whether an inductive argument is strong or weak.</span>

So according to this, given that Ryan is conducting an observational study on human behavior in different environments. To get the most accurate conclusion he needs to get the <span>greatest sample size, that is 50 Individuals. </span>
