This triangle is acute.

This is because none of the angles are equal to 90 degrees, so it is not a right triangle, and none of the angles are above 90 degrees, so it is not a obtuse triangle.

You have a bag of 12 marbles. Four are blue, 6 are green, 2 are red, and the others are yellow. What is the probability of drawi

8090 [49]

Answer:

$Probability = \frac{1}{11}$

Step-by-step explanation:

Given

$Blue = 4$

$Green = 6$

$Red = 2$

$Total = 12$

Required

Determine the probability of drawing red and green without replacement

This is calculated as follows:

$Probability = P(Red\ and\ Green)$

$Probability = P(Red)\ and\ P(Green)$

$Probability = \frac{n(Red)}{Total} * \frac{n(Green)}{Total - 1}$

We used Total - 1 because it's a probability without replacement:

$Probability = \frac{2}{12} * \frac{6}{12- 1}$

$Probability = \frac{2}{12} * \frac{6}{11}$

$Probability = \frac{1}{6} * \frac{6}{11}$

$Probability = \frac{1}{11}$

<em>Hence, the required probability is 1/11</em>

6/9 is a rational number. Select all the rational numbers that are equivalent to .

Marianna [84]

Option b) and c) is correct, i.e. 2/3 and 0.66(line over 66)7

6/9 is a rational number.
similar ration number can be given as -

<h3>What is rational number?</h3>

Rational numbers are the numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.

From the option, by above definition 2/3, 0.66(line over 66)7 seems to be an equivalent rational numbers because
6/9=2/3= 0.66(line over 66)7.

Thus, Rational numbers 2/3, 0.66(line over 66)7 are equivalent to 6/9.
