Hoi!

To add fractions with uncommon denominators, we must first find a common denominator of both fractions. To do this, we find the least common multiple.

The least common multiple of 8 and 12 is 24.

\frac{x}{24} +  \frac{x}{24}

Now, how many times do you have to add the denominator of the first fraction to get to 24?

8 + 8 + 8 = 24

3 times. Put the number 3 for the first numerator.

\frac{3}{24} +  \frac{x}{24}

How many times do you have to do the same for the denominator of the second fraction?

12 + 12 = 24

2 times. Put two for the second numerator.

\frac{3}{24} +  \frac{2}{24} = \frac{5}{24}

\frac{5}{24} is your answer. :)

arlik [135]

Answer:

  √7 ≈ 2.646

Step-by-step explanation:

The law of cosines is applicable. It tells you ...

  c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.

Filling in the given information, you have ...

  c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7

  c = √7 ≈ 2.646

The length of the third side is √7, about 2.646 units.

For the data set: {1.5, 2.3, 1.7, 3.6, 2.9, 4.2}, identify the percentile for the value 2.9.
antiseptic1488 [7]

Answer:

58.33%.

Step-by-step explanation:

We have been given a data set {1.5, 2.3, 1.7, 3.6, 2.9, 4.2} and we are asked to find the percentile for value 2.9.

First of all let us arrange our data points from smallest to largest as: {1.5, 1.7, 2.3, 2.9, 3.6, 4.2}.    

We can see that our data set has 6 data points and 2.9 is 4th data point.  

We will use percentile rank formula to solve our problem.  

P=\frac{(100*(i-0.5))}{n}, where,

P= Percentile rank,

i= Rank of the data point,

n = Total number of data points.

Upon substituting our given values we will get,

P=\frac{(100*(4-0.5))}{6}

P=\frac{(100*3.5)}{6}

P=\frac{350}{6}

P=\frac{350}{6}

P=58.333  

Therefore, percentile rank for the value 2.9 is 58.33%.
