The distance between two points needs to be measured, in meters. The true distance between the points is 10 meters, but due to m

easurement error we can’t measure the distance exactly. Instead, we will observe a value of 10+???? , where the error ???? is distributed (0,0.04) . Find the probability that the observed distance is within 0.4 meters of the true distance. Give an approximate numerical answer.

Answer:

The probability that the observed distance is within 0.4 meters is 0.955

Step-by-step explanation:

Margin of error (ME) from the mean can be calculated using the formula

ME=z×s where

  • z is the corresponding statistic of the probability that the observed distance is within 0.4 meters
  • s is the standard deviation of the observed error

Error is distributed as N(0,0.04) means that measurements have <em>standard deviation</em> 0.2, square root of 0.04.

<em>Margin of error</em> is given as 0.4 meters.

Thus 0.4=z×0.2  gives z=2 and the corresponding p-value is 0.045, which means that the probability of observing a margin of error 0.4 is 1-0.045=0.955.

Solve the following equation for x: 9x - 2<br> = 11x + 5
Nady [450]

Answer:

x= \frac{-7}{2}

Step-by-step explanation:

9x-2=11x+5

-9x       -9x

-2=2x+5

-5       -5

-7=2x

\frac{-7}{2} = \frac{2x}{2}

\frac{-7}{2}=x
