amm1812

Answer:  c.  0.0778

Step-by-step explanation:

Let  X is the number of non-authentic names in her sample with parameter :

n= 5 and p=40% = 0.40

Binomial probability distribution, the probability of getting success in x trials :-

P(X=x)=^nC_xp^x(1-p)^{n-x}

We have ,

P(X=0)=^{5}C_0(0.40)^0(1-0.40)^{5}\\\\=(1)(0.60)^{5}\\\\=0.07776\approx0.0778

Thus , the correct answer is option c. 0.0778

A cube has a surface area of 486 cm2. What is the side length ?
astraxan [27]
A Cube, has all equal sides, namely, the length, width and height
are all equal to each other

so..  notice the picture added here
you have really, 6 squares, stacked up to each other at the edges

so...what is the Area of one of those squares?
well, if the sides are equal, let's say the side is "x" long, then
the Area is x\cdot x \implies x^2

well, you have 6 of those squares, thus \bf \textit{surface area of a cube}=&#10;\begin{cases}&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)\\&#10; --------------\\&#10; x^2+x^2+x^2+x^2+x^2\\&#10;6x^2&#10;\end{cases}&#10;\\\\&#10;\textit{we know the Area is }486\ cm^2\qquad thus&#10;\\\\&#10;\textit{surface area}=6x^2\implies 486=6x^2

solve for "x", to get one side's length

Definition of a random sample
Gnesinka [82]

Answer:

Step-by-step explanation:

In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process, and each subset of k individuals has the same probability of being chosen for the sample as any other subset of k.
