(2 x 103 x 3 x 105) = 64890

2 x 10 -2 = 20 - 2 = 18

64890 / 18

3605

Or (206 x 315) / 20 - 2

The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean μ, the act
cluponka [151]

Answer: 0.3061.

Step-by-step explanation:

Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean \mu, the actual temperature of the medium, and standard deviation \sigma.

Let X be the random variable that represents the reading of the thermometer.

Confidence level : =95\%

We know that the z-value for 95% confidence interval is 1.96.

Then, we have

-1.96      z=\dfrac{X-\mu}{\sigma}

\Rightarrow\ -1.96\sigma  

But all readings are within 0.6° of \mu.

So, 1.96\sigma=0.6  

\Rightarrow\ \sigma=\dfrac{0.6}{1.96}=0.30612244898\approx0.3061

Hence, the required standard deviation will be

Help me answer the last question
givi [52]
We have the equation 1/2x + 200 =1200 so we know that we have 200 already as one of the numbers so 1/2 is half of x + 200 equals 1200 since we have 200 we know that 1/2 of x is going to be 1000 because 1000+200=1200 meaning x is 2000. So your answer would be x=2000 or 1/2 2000 + 200=1200
