It's only 19 because the terms don't both have m and n in them

Describe the sampling distribution of p(hat). Assume the size of the population is 30,000.n=800, p=0.6a) Determine the mean of t

Leno4ka [110]

Answer:

Standard deviation of the binomial distribution

= $\sqrt{n p q} = \sqrt{192} = 13.856$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given size 'n' = 800

The population proportion 'p'=0.6

Let 'X' be the random variable of the binomial distribution

a) mean of the binomial distribution = n p = 800 ×0.6

μ = 480

b) variance of the binomial distribution

= n p q

= 800 X 0.6 ×0.4

σ² = 192

Standard deviation of the binomial distribution

σ = $\sqrt{n p q} = \sqrt{192} = 13.856$

Which function has an inverse that is also a function? g(x) = 2x – 3 k(x) = –9x2 f(x) = |x 2| w(x) = –20.

blondinia [14]

The function has an inverse that is also a function is g(x) = 2x – 3.

The correct option is A.

<h3>Inverse function;</h3>

The inverse of a function is the equation where x and y have switched places.

We have to determine

Which function has an inverse that is also a function?

If when you solve for y again, the function passes the vertical line test, the inverse if a function.

1. Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;

$\rm y=\dfrac{(x-3)}{2}$

This is a line and is a function;

$\rm y=\dfrac{1}{2}x-\dfrac{3}{2}$

2. k(x) = -9x^2 has the inverse x = -9y^2 which simplifies to;

$\rm y=\sqrt{\dfrac{x}{-9}}$

This is a function but only for certain values of x.

3. f(x) = |x+2| is an absolute value function.

All absolute value functions do not have inverses which are functions.

4. w(x) = -20 does not have an inverse which is a function.

Hence, the function has an inverse that is also a function is g(x) = 2x – 3.

I have to give a name, values, and a level of measurement for these:

meriva

No. of years: I have lived for 73 years. (Value: # of years)

Phase of life: At 73, I'm in my late middle age. Early childhood was a long, long time ago, as was adolescence. And so on.

Amt. of money I have is confidential. ;) Well above mininum wage!

Type of psychological functioning: healthy, constructive (as opposed to schizophrenic, illusions of grandeur, etc.)

Religious training: essentially Protestant. There is some numerical fraction implicit in "essentially."

Abstract reasoning ability: Well above average ability in this department.

These are possible answers. Take them with a grain of salt.
