52 - 24 = 28

24 : 28 (fiction: nonfiction)

simplify

6 : 7

Just subtract 52 by 24 which will get you to 28, so your ratio is 28:24

Choose any positive integer. Powers of two here are not very interesting, so choose something else. If the number you have chose
Yakvenalex [24]

Answer:

Step-by-step explanation:

Let the integer be 6 for even and 7 for odd (say)

For 6, we divide by 2, now get 3.  Now we multiply by 3 and add 1 to get 10. Now since 10 is even divide by 5, now multiply by 3 and add 1 to get 16.  Now divide by 2 again by 2 again by 2 again by 2 till we get rid of even numbers.

The result is 1, so multiply by 3 and add 1 we get 4 now divide 2 times by 2 to get 1, thus this result now again repeats after 2 times.

Say if we select off number 3, multiply by 3 and add 1 to get 10 now divide by 5, now repeat the same process as above for 5 until we get 1 and it gets repeated every third time.

Thus whether odd or even after some processes, we get 1 and the process again and again returns to 1.

There are 48 students in Mrs. Mitra's computer class. At present, the ratio of the number of students to the number of computers
Svetach [21]

Answer:

4

Step-by-step explanation:

The computation is shown below:

Given that

There are total number of students i.e. 48

The ratio at present is 4:1

Now the computer needed to make the ratio be 3:1

So let us assume the number of students be 4x

And, the number of computers be x

So the 4x = 48

x = 12

So the computer be 12

Now the new ratio is 3:1

Students be 3x

And, computers be x

So

3x = 48

x = 16

Now the more computer needed is

= 16 - 12

= 4

hence, this is the answer but the same is not provided in the given options

Lieutenant Commander Data is planning to make his monthly (every 30 days) trek to Gamma Hydra City to pick up a supply of isolin
Nookie1986 [14]

Answer:

a

 N  =  209 \ unites

b

 N_{max}  =  249  

Step-by-step explanation:

From the question we are told that

   The daily demand is  d =  7/day

   The  standard deviation is  \sigma  =  3 /day

   The  service probability is  s =  95\%  =  0.95

    The number of chips  in the inventory is k  =  40

   The number of days in his monthly is  T =  30 \  days

    The lead time is  L  =  4

 

Generally the number he should order (optimal order ) is mathematically represented as

      N  =  d(L  +  T)+(\sigma_{T + L}  * z)  -k

Here \sigma__{T+L }} is the monthly standard deviation which is mathematically evaluated as

            \sigma__{T  + L}} =  \sqrt{(T + L) * 1^2}

=>         \sigma__{T  + L}}  =  \sqrt{34}

=>          \sigma__{T+L}} =  5.83

Also  z-value  for the  95% service probability  from the z-table  is  1.96

So

      N  =  7 *  (30 +4 ) + (1.96 *  5.83) - 40

=>     N  =  209 \ unites

For the maximum order quantity  k =  0

So

    N_{max} = d(L  +  T)+(\sigma_{T + L}  * z)  -0

=> N_{max}  =  7 *  (30 +4 ) + (1.96 *  5.83) - 0

=>  N_{max}  =  249
