If the complex number x = 3 + bị and x/2 = 13, which is a possible value of b?
Virty [35]

Answer:

23

Step-by-step explanation:

Given,

x = 3 + bị

Again,

x ÷ 2 = 13

Multiplying both the sides by 2, we can get.

(x ÷ 2) × 2 = 13 × 2

or, x = 26

As we find the value of x, we can now complete the complex number which is b.

x = 3 + bị

Putting the value of x, we can get,

26 = 3 + bi

or bi = 26 - 3

or, b = 23.

Therefore, the possible value of b = 23.

A group of 59 randomly selected students have a mean score of 29.5 with a standard
algol [13]

Answer:

29.5-1.671\frac{5.2}{\sqrt{59}}=28.37    

29.5+1.671\frac{5.2}{\sqrt{59}}=30.63    

And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence

Step-by-step explanation:

Information given

\bar X = 29.5 represent the sample mean

\mu population mean  

s= 5.2 represent the sample standard deviation

n=59 represent the sample size  

Confidence interval

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

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=59-1=58

The Confidence interval is 0.90 or 90%, the significance is \alpha=0.1 and \alpha/2 =0.05, and the critical value is t_{\alpha/2}=1.671

Now we have everything in order to replace into formula (1):

29.5-1.671\frac{5.2}{\sqrt{59}}=28.37    

29.5+1.671\frac{5.2}{\sqrt{59}}=30.63    

And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence
