What are the real zeros of the function g(x)=x^3+2x^2-x-2

Gre4nikov [31]

$g(x)=x^3+2x^2-x-2\\\\\text{The zeros:}\\\\g(x)=0\to x^3+2x^2-x-2=0\\\\x^2(x+2)-1(x+2)=0\\\\(x+2)(x^2-1)=0\iff x+2=0\ \vee\ x^2-1=0\\\\x+2=0\ \ \ |-2\\x=-2\\\\x^2-1=0\ \ \ |+1\\x^2=1\to x=\pm\sqrt{1}\to x=-1\ \vee\ x=1\\\\\text{Answer:}\ x=-2\ or\ x=-1\ or\ x=1$

mina [271]

Answer:

Mean: 0.400

Standard error: 0.022

Step-by-step explanation:

We are taking samples of size n=500 out of a population with parameter p=0.40.

The expected distribution is the sampling distribution of sampled proportions. This distribution has parameters that are calculated as:

Mean: the mean of the sampling distribution is equal to the population proportion, as it is not biased.

In this case, the mean of this sampling distribution is p=0.40.

Standard error: the standard error depends on the population proportion and the sample size. It is calculated as:

$\sigma_p=\sqrt\dfrac{p(1-p)}{N}}=\sqrt\dfrac{0.4*0.6}{500}}=\sqrt{0.00048}=0.022$

being p: population proportion, N: sample size.

Answer:

See Explanation

Step-by-step explanation:

$\frac{mass \: of \: earth}{mass \: of \: human} = \frac{5.97 \times {10}^{24} }{6.35 \times {10}^{1} } \\ \\ = 0.94015748 \times {10}^{24 - 1} \\ \\ = 0.94015748 \times {10}^{23} \\ \\ = 9.4\times {10}^{22} \\ \\ \therefore \: mass \: of \: earth \\ =( 9.4\times {10}^{22} ) \times mass \: of \: human$
