<span>Step  1  :</span>Isolate the square root on the left hand side :

     Original equation 
<span>     12 = 19-√3x-11

</span>     Isolate
<span>     √3x-11 = -12+19

</span>      Tidy up 
<span>     √3x-11 = 7

</span>

<span>Step  2  :</span>Eliminate the radical on the left hand side :

     Raise both sides to the second power
<span>     (√3x-11)2 = (7)2

</span>     After squaring 
<span>     3x-11 = 49

</span>

<span>Step  3  :</span>Solve the linear equation :

     Rearranged equation
<span>      3x  -60 = 0
</span>
     Add  60  to both sides
<span>      3x  = 60
</span>
     Divide both sides by 3
     A possible solution is :
<span>     x = 20
</span>

<span>Step  4  :</span>Check that the solution is correct :

     Original equation, root isolated


<span>     √3x-11 = 7

</span>     Plug in 20 for  x 
<span>      √3•(20)-11 = 7
</span>      Simplify
     <span> √49 = 7</span>
     Solution is: 
<span>      x = 20
</span>

One solution was found :                  <span>      x = 20

</span>

The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!

What is the probability of obtaining a sample mean of 53 or less from a sample of 50​?
Artemon [7]
Sampling errorThe natural discrepancy, or amount of error, between a sample statistic and its corresponding population parameter.distribution of sample means<span>The collection of sample means for all of the possible random samples of a particular size (n) that can be obtained from a population.</span>sampling distributionA distribution of statistics obtained by selecting all of the possible samples of a specific size from a population.central limit theorem<span>For any population with mean μ and standard deviation σ, the distribution of sample means for sample size n will have a mean of μ and a standard deviation of σ/√n and will approach a normal distribution as n approaches infinity.</span><span>expected value of M</span>The mean of the distribution of sample means is equal to the mean of the population of scores, μ, and is called this.<span>standard error of M</span><span>The standard deviation for the distribution of sample means. Identified by the symbol σ˯M. This standard error provides a measure of how much distance is expected on average between a sample mean (M) and the population mean (μ).</span>law of large numbers<span>States that the larger the sample size (n), the more probable it is that the sample mean is close to the population mean.</span>

Simplify as far as possible without using a calculator.2√3×4√5
maks197457 [2]

Answer:

= 8√15

Step-by-step explanation:

Steps

2√3 x 4√5

Apply radical rule: √a√b=√ab.

√3 √5 = √3x 5

=2√3x 5 x 4

Multiply the numbers: 3 x 5= 15

=2√15 x 4

Multiply the numbers: 2 x 4 =8

= 8√15

2√3 x 4√5 = 8√15 (Decimal: 30.98386..)
