Every Thursday, Matt and Dave's Video Venture has “roll-the-dice" day. A customer may choose to roll two fair dice and rent a se

Using the normal distribution, it is found that there is a 0.1357 = 13.57% probability that the total  amount paid for these second movies will exceed $15.00.

In a <em>normal distribution</em> with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
  • For n instances of a normal variable, the mean is n\mu and the standard error is s = \sigma\sqrt{n}

In this problem:

  • Mean of $0.47, standard deviation $0.15, hence \mu = 0.47, \sigma = 0.15
  • 30 instances, hence n\mu = 30(0.47) = 14.1, s = 0.15\sqrt{30} = 0.8216

The probability is <u>1 subtracted by the p-value of Z when X = 15</u>, hence:

Z = \frac{X - \mu}{\sigma}

Considering the n instances:

Z = \frac{X - n\mu}{s}

Z = \frac{15 - 14.1}{0.8216}

Z = 1.1

Z = 1.1 has a p-value of 0.8643.

1 - 0.8643 = 0.1357.

0.1357 = 13.57% probability that the total  amount paid for these second movies will exceed $15.00.

A blue rope in Garret's camping backpack is 6 yards long. The blue rope is 3 time as long as a red rope. A yellow rope is 2 feet
vitfil [10]

Answer:

175 inches, 14.58 ft

Step-by-step explanation:

Length of blue rope = 6 yards

also  Length of blue rope  = length of red rope * 3

=> 6 yards = length of red rope * 3

=> length of red rope = 6/3 = 2 yards

____________________________________

length of yellow rope =  2feet 7 inches shorter than red rope

1 yard = 36 inch

length of red rope in inches = 2 *36 = 72 inches

1 feet = 12 inches

difference of yellow and red rope in inches = 12* 2 + 7 = 31

length of yellow rope in inches = 72 inches -(12* 2 + 7 )= 72-31 = 41 inches

length of blue rope in inches = 36*6 = 216 inches

difference in length between the blue rope and the yellow rope = 216 - 41

                                                                                               = 175 inches

difference in length between the blue rope and the yellow rope in feet = 175/12 = 14.58 ft
