Answer:
Step-by-step explanation:
All those words, when the math is so much clearer!
x = (9±√(9^2-4*1*5))/2 = (9±√101)/2
The answer would be 0.37.
Answer:
16
Step-by-step explanation:
Well first we need to plug in 10 for g and 6 for h.
2/5(10) + 3(6) - 6
4 + 18 - 6
22 - 6
16
<em>Thus,</em>
<em>the answer is 16.</em>

Answer:
All real numbers
Step-by-step explanation:
To find the range of the function 
draw the graph of ths function (see attached diagram for details).
Since the base of the logarithm is 
the graph is increasing and passes through the point (1,0).
The domain of this function is
The range of this function is
or all real numbers.
4,034.06 ,5,965.94 are confidence interval for the population average wages at the factory.
What is confidence interval estimation?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. Another term for probability in statistics is confidence.
The formula for confidence interval estimation is:
μ = M ± Z(sM)
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
M = 50000
Z = 2.58
sM = √(30002/64) = 375
μ = M ± Z(sM)
μ = 50000 ± 2.58*375
μ = 50000 ± 965.94
μ = 4,034.06 ,5,965.94
