In a large population, 66 out of every 100 people like dogs better than cats. You would like to find out how likely it is a grou

p of cat-lovers from this population will come together by random chance. You decide to use a sampling distribution to help your analysis, and you believe that a sample size of 50 will be large enough to generate your data, so you select 50 people at random to participate in your study.
a) Using the information above, determine the probability of success - that is, the likelihood of an individual preferring cats - for the general population. Enter a number answer only. Round your answer to two decimal places.
b) Using the information above, determine the probability of failure - that is, the likelihood of an individual preferring dogs - for the general population. Enter a number answer only. Round your answer to two decimal places.
c) Using the information above, determine the sample size used in the study.
d) Using the information above, determine the mean of the sampling distribution for all samples of size 50. Enter a number answer only.
e) Using the information above, determine the standard deviation of the sampling distribution for all samples of size 50. Enter a number answer only. Round your answer to two decimal places.

What is the probability of getting 6 as a product explanation and calculation
Mrrafil [7]

For an individual die roll, the probability of rolling 6 is \dfrac{1}{6}

6

1

.

Effectively, this problem is asking for P(\text{1st roll is 6}\cap\text{2nd roll is 6})P(1st roll is 6∩2nd roll is 6).

Using the rule of product, this is:

\dfrac{1}{6}\times\dfrac{1}{6}=\dfrac{1}{36}

6

The length of the base edge of a pyramid with a regular hexagon base is represented as x. The height of the pyramid is 3 times l
sergij07 [2.7K]

Answer:

(a)

h=3x

(b)

A=\frac{\sqrt{3} }{4} x^2

(c)

A=\frac{3\sqrt{3} }{2} x^2

(d)

V=\frac{3\sqrt{3} }{2} x^3 units^3

Step-by-step explanation:

We are given a regular hexagon pyramid

Since, it is regular hexagon

so, value of edge of all sides must be same

The length of the base edge of a pyramid with a regular hexagon base is represented as x

so, edge of base =x

b=x

Let's assume each blank spaces as a , b , c, d

we will find value for each spaces

(a)

The height of the pyramid is 3 times longer than the base edge

so, height =3*edge of base

height=3x

h=3x

(b)

Since, it is in units^2

so, it is given to find area

we know that

area of equilateral triangle is

=\frac{\sqrt{3} }{4} b^2

h=3x

b=x

now, we can plug values

A=\frac{\sqrt{3} }{4} x^2

(c)

we know that

there are six such triangles in the base of hexagon

So,

Area of base of hexagon = 6* (area of triangle)

Area of base of hexagon is

=6\times \frac{\sqrt{3} }{4} x^2

=\frac{3\sqrt{3} }{2} x^2

(d)

Volume=(1/3)* (Area of hexagon)*(height of pyramid)

now, we can plug values

Volume is

=\frac{1}{3}\times\frac{3\sqrt{3} }{2} x^2\times (3x)

V=\frac{3\sqrt{3} }{2} x^3 units^3
