Solve x2 + 2x + 9 = 0
Keith_Richards [23]
x^2+2x+9=0 \\ \\
a=1 \\ b=2 \\ c=9 \\ b^2-4ac=2^2-4 \times 1 \times 9=4-36=-32 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-2 \pm \sqrt{-32}}{2 \times 1}=\frac{-2 \pm \sqrt{-16 \times 2}}{2}=\frac{-2 \pm 4i\sqrt{2}}{2}=-1 \pm 2i\sqrt{2}

The answer is D.

Let μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ &gt; 5, determine the
noname [10]

Answer: 0.0708

Step-by-step explanation:

Let μ denote the true average reaction time to a certain stimulus.

To determine : The P-value for a z test of H0: μ = 5 versus Ha: μ > 5.

In the given set of hypothesis , the alternative hypothesis is right -tailed , so the test is a right tailed test .

Given test statistic : a) z= 1.47

Now, the p-value for the right tailed test :

P(z>1.47)=1-P(z\leq1.47)\ \ [\because P(Z>z)=1-P(Z\leq z)]

=1-0.9292=0.0708

[Using the p-value table for z]

Hence, the required P-value = 0.0708
