Number of possible arrangements of x elements:

The number of possible arrangments of x elements is given by:

A_{x} = x!

In this question:

12 teams, so arrangment of 12 elements.

A_{12} = 12! = 479001600

The teams can be placed in 479,001,600 ways.

If y=98 when x=14, find y when x= - 4
sesenic [268]

Answer:

-28

Step-by-step explanation:

If y = 98 when x is 14, y is always seven times x. We know this because x = y/7.

So if Y is seven times bigger, -4 * 7 = -28

The difference between teenage female and male depression rates estimated from two samples is 0.08. The estimated standard error
Ede4ka [16]

Answer: = ( 0.0384, 0.1216)

Therefore at 95% confidence interval the difference between teenage female and male depression rates is between ( 0.0384, 0.1216)

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = 0.08

Standard deviation r = 0.03

Number of samples n = 2

Confidence interval = 95%

z(at 95% confidence) = 1.96

Substituting the values we have;

0.08+/-1.96(0.03/√2)

0.08+/-1.96(0.021213203435)

0.08+/-0.0416

= ( 0.0384, 0.1216)

Therefore at 95% confidence interval= ( 0.0384, 0.1216)
