The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean μ, the act
ira [324]

Answer:

The standard deviation would have to be 0.05.

Step-by-step explanation:

We can solve this problem using the 68-95-99.7 rule for normal distributions:

The rule states that:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviations of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

What would the value of σ have to be to ensure that 95% of all readings are within 0.1° of μ?

This means that 2 standard deviations would need to be within 0.1 of the mean. So

2\sigma = 0.1

\sigma = \frac{0.1}{2}

\sigma = 0.05

The standard deviation would have to be 0.05.

If (-3)^-5=1/x what is the value of x<br><br> Answers:<br><br> -243<br> -1/243<br> 1/243<br> 243
Inga [223]
Solve -3^-5.

Knowing that x^{-1} = \frac{1}{x}, then -3^{-5}= \frac{-1}{243}

That means that x = -243.

F-20f=21 what’s the answer
Virty [35]

\bold{[ \ Answer \ ]}

\boxed{\bold{F \ = \ -\frac{21}{19} }}

\bold{[ \ Explanation \ ]}

  • \bold{Solve: \ f \ - \ 20f \ = \ 21}

-----------------------------------

  • \bold{Add \ Similar \ Elements:f-20f=-19f}

\bold{-19f=21}

  • \bold{Divide \ Both \ Sides \ By \ -19}

\bold{\frac{-19f}{-19}=\frac{21}{-19}}

  • \bold{Simplify}

\bold{F \ = \ -\frac{21}{19}}

\boxed{\bold{[] \ Eclipsed \ []}}
