Using the normal distribution, it is found that the two readings that are cutoff values separating the rejected thermometers from the others are -1.96ºC and 1.96ºC.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
.
The z-score that cuts off the bottom and top 2.5% of the distribution is
, hence:


X = -1.96


X = 1.96
The two readings that are cutoff values separating the rejected thermometers from the others are -1.96ºC and 1.96ºC.

Answer:
18
Step-by-step explanation:
Subtract 6 from both sides so the equation becomes 1/9x=2. Multiply by the reciprocal on both sides (9)1/9x=2(9).
This cancels out to x=18
<em>Answer:</em>
<em>√81 = 9 </em>
<em>Step-by-step explanation:</em>
<em>√(32+42) = √74</em>
<em>√64 < √74 < √81</em>
<em> +10 ⇔ +7</em>
<em>the nearest whole number √81 = 9 </em>
Answer:
-2948
Step-by-step explanation:
Two signs (addition and subtraction) together makes subtraction when having a positive sign and a negative sign
Then subtract -38 and 2910
