1. The cube root of 384 can be rewritten as the cube root of (8*48). That can be simplified to 2 cube root of 48. That can be simplified down further to 2 cube root of (6*8), which is 2*2 cube root of 6, or 4 cube root of 6. So, the answer is C.

You do the same thing for each of the problems. If you actually want me to just give you the answers, they are:
1. C
2. D
3. D

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%.
