How do you do probability on numbers

1 answer:

4 0

First, the denominator is the amount of subjects (for example colors). Say the question is find the probability of red. Say there is 4 blue dots, 9 red dots, 2 yellow dots, and 3 orange dots. The denominator would be 18 (the amount of dots). The numerator would be 9 because that is how many dots that were red are there. The answer would be 9/18 = 1/2. I hope his helps :)

Solve 3x^2 +11x+6=0 Answers -2/3,-3 2/3,3 0

Annette [7]

Answer: First Option

$x_1=-\frac{2}{3}$ and $x_2=-3$

Step-by-step explanation:

We have the following quadratic equation:

$3x^2 +11x+6=0$

To solve this equation use the quadratic formula

For an equation of the form:

$ax ^ 2 + bx + c = 0$

The quadratic formula is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

Note that in this case: $a=3,\ b=11,\ c=6$

Then:

$x=\frac{-11\±\sqrt{11^2-4(3)(6)}}{2(3)}$

$x=\frac{-11\±\sqrt{121-72}}{6}$

$x=\frac{-11\±\sqrt{49}}{6}$

$x=\frac{-11\±7}{6}$

$x_1=\frac{-11+7}{6}$

$x_1=-\frac{2}{3}$

$x_2=\frac{-11-7}{6}$

$x_2=\frac{-18}{6}$

$x_2=-3$

The solutions are: $x_1=-\frac{2}{3}$ and $x_2=-3$

A. This study is an observation study as there is manipulative to the data on the part of the researcher. They only collected information based on what was seen and observed. There were no treatment conditions.

B. It is not reasonable to conclude that writing the essay in cursive is the cause for higher scores as the causation factor inducing higher scores here in this case might not be on how the essays are put down. So an experiment will be needed to be carried out to find this out.

What number should be divided by 32 to get?

Rina8888 [55]

The number should be divided by 32 to get 64 is 1/2 .

Given :

number should be divided by 32 to get 64 .

Let x be the number.

Number :

A number is an arithmetic value used for representing the quantity and used in making calculations .

64 = 32 / x

64 / 1 = 32 / x

cross multiplication

64 * x = 32 * 1

64 x = 32

divide by 64 on both sides

64x / 64 = 32 / 64

x = 32 / 64

x = 1/2

Therefore the number 1/2 should be divided by 32 to get 64.
