I got 24

Explanation:

12 divided by 1/2 =
12= whole number
1= Numerator
2= Denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
12x2/1 = 24/1
Thus, the answer to 12 divided by 1/2 in fraction form is 24/1
But to make the answer 12 divided by 1/2 in decimal form, you simply divide the numerator from the fraction answer:
24/1 = 24

The area of a rectangle is 42 square inches and one side is 12 inches long find the perimeter of the rectangle show your work
uranmaximum [27]
So first of all we need to know that area is length times width
Area = L x W 
since we know the area is 42 and the length is 12 lets plug those in
42 = 12 x W 
now we dont know what W is yet but we can figure it out by dividing 42 by 12
42/12 = 3.5 
So W = 3.5!
but its asking for the perimeter and we know that perimeter is all of the sides of the rectangle added up. Heres a picture
   
       ___3.5___
      |                 |
      |                 |
 12 |                 |  12 
      |                 |
      ************
             3.5

see now we just add those all up together:)

12 + 12 + 3.5 + 3.5 = 31!!
so our perimeter is 31 inches:)
have a good one

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.
