Cuales son los minerales que se utiliza para generar energia nuclear

anastassius [24]

Answer:

El uranio es el combustible más utilizado para producir energía nuclear. Eso es porque los átomos de uranio se separan con relativa facilidad. El uranio también es un elemento muy común que se encuentra en las rocas de todo el mundo.

Explain the difference between a greatest common factor and a least common multpule

hodyreva [135]

Answer:

The Greatest Common Factor, the GCF, is the biggest ("greatest") number that will divide into (that is, the largest number that is a factor of) both 2940 and 3150. On the other hand, the Least Common Multiple, the LCM, is the smallest ("least") number that both 2940 and 3150 will divide into.

To illustrate the effects of driving under the influence (DUI) of alcohol, a police officer brought a DUI simulator to a local h

Oksanka [162]

Answer:

a) If we design the experiment on this way we can check if we have an improvement with the method used.

We assume that we have the same individual and we take a value before with the normal impaired condition and the final condition is the normal case.

b) $-0.96-2.306\frac{0.359}{\sqrt{9}}=-1.24$

$-0.96+2.306\frac{0.359}{\sqrt{9}}=-0.69$

The 95% confidence interval would be given by (-1.24;-0.69)

Step-by-step explanation:

Part a

If we design the experiment on this way we can check if we have an improvement with the method used.

We assume that we have the same individual and we take a value before with the normal impaired condition and the final condition is the normal case.

Part b

For this case first we need to find the differences like this :

Normal, Xi 4.47 4.24 4.58 4.65 4.31 4.80 4.55 5.00 4.79

Impaired, Yi 5.77 5.67 5.51 5.32 5.83 5.49 5.23 5.61 5.6

Let $d_i = Normal -Impaired$

$d_i : -1.3, -1.43, -0.93, -0.67,-1.52, -0.69, -0.68, -0.61, -0.81$

The second step is calculate the mean difference

$\bar d= \frac{\sum_{i=1}^n d_i}{n}=-0.96$

The third step would be calculate the standard deviation for the differences, and we got:

$s_d =\frac{\sum_{i=1}^n (d_i -\bar d)^2}{n-1} =0.359$

The confidence interval for the mean is given by the following formula:

$\bar d \pm t_{\alpha/2}\frac{s_d}{\sqrt{n}}$ (1)

In order to calculate the critical value $t_{\alpha/2}$ we need to find first the degrees of freedom, given by:

$df=n-1=9-1=8$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.025,8)".And we see that $t_{\alpha/2}=2.306$
