Answer:

The value of the variable 'b' is 3 and GH is 9

Step-by-step explanation:

Given:

GI = 5b+1\\\\HI=4b-5\\ \\HI=7

H is between G and I

Such that G - H - I

To Find:

GH = ?

Solution:

On Substituting HI we get

4b-5=7\\\\\therefore 4b=7+5=12\\\\b=\dfrac{12}{4}=3

Substituting 'b' in HI and GI we get

HI=4\times 3 -5=12-5=7\\\\\therefore HI = 7

GI=5\times 3 +1=15+1=16\\\\\therefore GI = 16

Now, by Line Addition Property we get

GI=GH+HI

Substituting 'HI' and 'GI' we get

16=GH+7\\\\\therefore GH=16-7=9

The value of the variable 'b' is 3 and GH is 9

A nutrition laboratory tested 25 "reduced sodium" hotdogs of a certain brand, finding that the mean sodium content is 310 mg wit
inessss [21]

Answer:

The  95% confidence interval is  295.9 < \mu< 324.1

A   95% level of confidence mean that there is 95%  chance  that the true population mean will be in this interval

Step-by-step explanation:

From the question we are told that

    The sample size is  n  =  25

    The mean is  \= x  =  310 \ mg

     The standard deviation is  \sigma =  36 \ mg

Given that the confidence level is  95% then the level of significance is mathematically represented as

           \alpha  =  100 - 95

=>        \alpha  =  5\%

=>        \alpha  =  0.05

Next we obtain the critical value of  \frac{\alpha }{2} from the normal distribution table , the value is  

           Z_{\frac{\alpha }{2} } =Z_{\frac{0.05 }{2} }  =  1.96

Generally the margin of error is mathematically represented as

        E =  Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

substituting values

        E =  1.96 *  \frac{36 }{\sqrt{25} }

        E = 14.1

The 95% level of confidence interval  is mathematically represented as

      \= x - E < \mu

substituting values

     310- 14.1 < \mu< 310+ 14.1

     295.9 < \mu< 324.1

The  95% level of confidence mean that there is 95%  chance  that the true population mean will be in this interval
