you need to make a closed top rectangular tank that is 19 inches wide, 30 inches deep and 18 inches high. how many square feet o

Maslowich

Length in feet multiplied by width in feet multiplied by height in feet divided by 27 equals cubic yards needed.

When dealing in inches: convert inches to feet by dividing by 12.

For example: pour a 25 ft. sidewalk 5 ft. wide and four inches deep.

(25’ x 5 ‘ x 0.333’) / 27 = 1.54 cubic yards

Note* we achieved 0.333 ft. by taking four inches and dividing by twelve.

Another example: yardage for an 80 ft. driveway, 24 ft. wide and 5 inches deep.

(80’ x 24’ x 0.416’) / 27 = 29.58 cubic yards

Suppose the time it takes a barber to complete a haircuts is uniformly distributed between 8 and 22 minutes, inclusive. Let X =

salantis [7]

Answer:

$P(X>14)= 1-P(X$

And replacing we got:

$P(X>14)= 1- \frac{14-8}{22-8}= 0.5714$

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714

Step-by-step explanation:

We define the random variable of interest as x " time it takes a barber to complete a haircuts" and we know that the distribution for X is given by:

$X \sim Unif (a= 8, b=22)$

And for this case we want to find the following probability:

$P(X>14)$

We can find this probability using the complement rule and the cumulative distribution function given by:

$P(X$

Using this formula we got:

$P(X>14)= 1-P(X$

And replacing we got:

$P(X>14)= 1- \frac{14-8}{22-8}= 0.5714$

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714
