Vitek1552 [10]3 years ago
3 0

Answer:

x + y + z = 123

Step-by-step explanation:

x:y:z = 7:2:5

Let x = 7a, y = 2a, z = 5a

Since x - z = 18

Therefore,

7a - 5a = 18

2a + 18

a = 18/2

a = 9

7a = 7*9 = 63

2a = 2*9= 15

5a = 5*9 = 45

x + y + z = 63 + 15 + 45

x + y + z = 123

Determine whether each of these sets is the power set of aset,wherea and b are distinct elements. a) ∅ c) {∅,{a},{∅,a}} b) {∅,{a
bija089 [108]

Answer:

{∅, {a}, {b}, {a,b}}

Step-by-step explanation:

The value of power of a set is generalized by using the formula,

Power of a set (P) = 2^n where n is the number of element in the set.

Given two distinct elements a and b say;

A = {a,b}

n(A) = 2 i.e the number of elements in the set is 2. Therefore the power of the set will be 2^n which gives 2^2 = 4.

P(A) = 4 means there are 4 subsets of the given set. Subsets are sets of elements that can be found in the set. The subsets of element A will be;

{∅, {a}, {b}, {a,b}} which gives 4 elements in total.

Note that empty set ∅ is always part of the subset of any given set

A successful basketball player has a height of 6 feet 5 inches, or 196 cm. Based on statistics from a data set, his height conve
SVETLANKA909090 [29]

Answer:

The player's height is 3.02 standard deviations above the mean.

Step-by-step explanation:

Consider a random variable <em>X</em> following a Normal distribution with parameter <em>μ</em> and <em>σ</em>.

The procedure of standardization transforms individual scores to standard scores for which we know the percentiles (if the data are normally distributed).  

Standardization does this by transforming individual scores from different normal distributions to a common normal distribution with a known mean, standard deviation, and percentiles.

A standardized score is the number of standard deviations an observation or data point is above or below the mean.

The standard score of the random variable <em>X</em> is:

Z=\frac{X-\mu}{\sigma}

These standard scores are also known as <em>z</em>-scores and they follow a Standard normal distribution, i.e. <em>N</em> (0, 1).

It is provided that the height of a successful basketball player is 196 cm.

The standard value of this height is, <em>z</em> = 3.02.

The <em>z</em>-score of 3.02 implies that the player's height is 3.02 standard deviations above the mean.
