Describe the relationship between the variables.

sertanlavr [38]

Relationship between the variables are
(a) As the age increases, the height increases.
No relationship between variables.
(a) As the age increases, height decreases.
(b) As the height decreases, the age decreases.

Step-by-step explanation:

If visually found a child born till his age of elder he has increased.
It is clearly true that as the age increases height increases.
Child is born at some point of time with a particular height.
It is never an association between age increases and height reduces.
Age is again started at some point of time, it cannot decrease.
After descriptive statistics there something called predictive.
Describing the data is one way of understanding statistics.
It is mean,median mode where the particularly number stands.
Predictive is the next stage an association of variables.
Variables are very important in analysis it basically attribution.
In order to find any analyse test studies are important variables to.

Eric's class consists of 12 males and 16 females. If 3 students are selected at random, find the probability that they

Reptile [31]

Answer:

The probability that all are male of choosing '3' students

P(E) = 0.067 = 6.71%

Step-by-step explanation:

Let 'M' be the event of selecting males n(M) = 12

Number of ways of choosing 3 students From all males and females

$n(M) = 28C_{3} = \frac{28!}{(28-3)!3!} =\frac{28 X 27 X 26}{3 X 2 X 1 } = 3,276$

Number of ways of choosing 3 students From all males

$n(M) = 12C_{3} = \frac{12!}{(12-3)!3!} =\frac{12 X 11 X 10}{3 X 2 X 1 } =220$

The probability that all are male of choosing '3' students

$P(E) = \frac{n(M)}{n(S)} = \frac{12 C_{3} }{28 C_{3} }$

$P(E) = \frac{12 C_{3} }{28 C_{3} } = \frac{220}{3276}$

P(E) = 0.067 = 6.71%

<u><em>Final answer</em></u>:-

The probability that all are male of choosing '3' students

P(E) = 0.067 = 6.71%
