The answer is never, that is, on a 2 dimensional plane. You can perform an experiment to see why it is the case. On curved surfaces though, two lines can intersect one another more than once. For instance, on the surface of planet Earth, two lines can intersect one another, both at the Earth's North Pole and South Pole.

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

Write the product in its simplest form: -5x*8x^7

Ivenika [448]

Answer:

-40 x^8

Step-by-step explanation:

-5x*8x^7

We know that a^b * a^c = a^(b+c)

-5 *8 * (x*x^7)

-40 *(x^1 * x^7)

-40 x^(1+7)

-40 x^8
