The industrial process that is used to convert a fuel to gasoline is carried out at a temperature range of 660 degrees°F to 790

NARA [144]

Answer:

$|F-725|$

With F represent the variable of interest:

$-65< F-725< 65$

$-65+725< F< 65+725$

$660 < F< 790$

Step-by-step explanation:

For this case we have a normal limits for the temperature Range. The minimum is 660 F and the maximum 790 F.

We can find the midpoint of this interval like this:

$Midpoint= \frac{660+790}{2}= 725$

And the difference between the midpoint and the limits are:

$|790-725|= 65$

$|680-725|= 65$

So then we can create the following inequality:

$|F-725|$

With F represent the variable of interest.:

$-65< F-725< 65$

$-65+725< F< 65+725$

$660 < F< 790$

If an hourglass takes an average of 1 hour to empty a full cycle, what probability of time does it take longer than 72 minutes i

Arturiano [62]

Answer:

0.82%

Step-by-step explanation:

First find the z-score.

z = (x − μ) / σ

z = (72 − 60) / 5

z = 2.4

Use a chart or calculator to find the probability.

P(Z > 2.4) = 1 − P(Z < 2.4)

P(Z > 2.4) = 1 − 0.9918

P(Z > 2.4) = 0.0082
