What is the value of x in the equation below?
sveta [45]

Answer: C

Step-by-step explanation:

1+2e^x+1=9

2e^x+1=9-1

e^x+1= 8/2

e^x+1 = 4

Here we can applicate the Ln:

ln e^x+1 = ln 4

Applicating the log property for exponent:

(x+1).ln e = ln 4

Ln e = 1, so:

x+1 = ln 4

x = ln 4-1

QveST [7]

Complete Question

A measurement template with a historical value of 25.500 mm is measured 27 times and a mean value of 25.301 mm is recorded. What is the percent bias when the tolerance is +/- 0.3?

Answer:

The percent bias is  B = 33.167 \%  

Step-by-step explanation:

From the question we are told that

   The historical value  is  S = 25.00 \ mm

   The number of times it is measured is  n  =  7  

    The mean value is  \= x = \frac{\sum x_i }{n} = 25.301 \ mm

    The tolerance is  t =\pm 0.3 = 0.3 - (-0.3) = 0.6

Generally the percent bias is mathematically represented as

      B = 100 * \frac{\= x - \tau }{ t}

=>  B = 100 * \frac{25.301 - 25.5000 }{0.6}

=>  B = 33.167 \%
