For which binomial distribution would a poisson approximation be acceptable? a. n = 60, π = 0.08

1 answer:

8 0

Generally, when n is large, say >=20, and p is small, say <0.05, it would be safe to approximate with a Poisson distribution.

However, the fact that np=4.8 <<10, and n=60 >>20 (I prefer working with 30), can justify approximating with Poisson.

So you see that when n is large, there is more tolerance.

The equation tan (x+pi/6) is equal to

Degger [83]

Answer:

(√3 tan x + 1) / (√3 - tan x)

Step-by-step explanation:

$tan (x+\frac{\pi }{6})\\= \frac{tan x+\frac{1}{\sqrt{3} } }{1-\frac{tan x}{\sqrt{3} } } \\= \frac{\sqrt{3} tan x + 1}{\sqrt{3} -tan x}$

PLEASE HELP ME!!! I'M BAD AT GEOMETRY!!!

7nadin3 [17]

Answer:

Manuel would be correct, the volumes would be equal.

Step-by-step explanation:

The formulae for finding the volume of pyramids and cones both include dividing three (multiplying by $\frac{1}{3}$ ).

Square pyramid formula: $\frac{1}{3}$ ×B×h where B is the area of the base. By plugging in numbers we have that B=314.159 and h=5. 314.159× $\frac{1}{3}$ ×5=523.5983.

Cone formula: The basic formula is the same: $\frac{1}{3}$ ×B×h, but the area of the base is found using the circle formula of π×r². For the cone we have B=314.159 and h=5. 314.159× $\frac{1}{3}$ ×5=523.5983.

Since both of these formulas came up with the same answer, we can conclude that Cone W has the same volume as Pyramid X, which is Manuel's answer.

Quick!!!!!!!!!!!!!!!

Degger [83]

Answer: discrete.

Step-by-step explanation:

Discrete variable

It is a variable whose value is evaluated by counting.

Example: Number of books published in a month.

Continuous variable

It is a variable whose value is evaluated by measuring ( not countable).

Example: Distance: 1.52 m

Since the number of dental visits a randomly chosen person had for the past 5 years is a countable.

here, Variable: Let X =number of dental visits a randomly chosen person had for the past 5 years

So, the random variable described is discrete.
