What is the standard deviation of a sampling distribution called?
GarryVolchara [31]

Answer: Standard error.

Step-by-step explanation:

If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean [tex]\overline{x}[/tex] is known as standard error which depends on population standard deviation (\sigma) and the sample size (n).

\sigma_x=\dfrac{\sigma}{\sqrt{n}}

It measure the variability in the sample statistics that happens by chance.

Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.

20x^2-30=4x solve for x
ankoles [38]

Answer:

x=1.3288 or -1.1288

Step-by-step explanation:

Given 20x^{2}-30=4x

    Subtract 4x from both sides

         20x^{2}-4x-30=0

Since we can factor out 2 from whole equation, let's factor out 2.

         2(10x^{2}-2x-15)=0

Divide with 2 on both sides

         10x^{2}-2x-15=0

We got the quadratic equation, we can solve for x using quadratic formula.

x=\frac{-b\pm\sqrt{b^{2}-4ac} } {2a}

x=\frac{2\pm\sqrt{2^{2}-4X10X(-15)} } {2X10}

x=\frac{2\pm\sqrt{604} }{20}

x=\frac{2\pm2\sqrt{151}}{20}

x=1.3288or-1.1288
