Height of window 0.6 feet less than 2.5 times it width height of window 4.9 feet
AURORKA [14]
Suggest you use some punctuation here:  "The h<span>eight of window is 0.6 feet less than 2.5 times it width.  The height of window  is 4.9 feet.  Find the width of the window."

height of window = 4.9 feet = 2.5(width) - 0.6 feet.

simplify this equation by adding 0.6 feet to both sides of the equation:

4.9 feet + 0.6 feet = 2.5 (width); find width:

5.5 feet = 2.5 (width)

Dividing both sides of this equation by 2.5 will result in an equation for the width of the window, in feet.</span>

Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval. What
dezoksy [38]

Answer:

29.49% probability that a production time is between 9.7 and 12 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d, in which d is greater than c, is given by the following formula.

P(c \leq X \leq d) = \frac{d - c}{b-a}

Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval.

This means that a = 8, b = 15.8

What is the probability that a production time is between 9.7 and 12 minutes?

d = 12, c = 9.7.

So

P(c \leq X \leq d) = \frac{d - c}{b-a}

P(9.7 \leq X \leq 12) = \frac{12 - 9.7}{15.8 - 8} = 0.2949

29.49% probability that a production time is between 9.7 and 12 minutes
