Answer:

  3 1/2 hours

Step-by-step explanation:

If there are 8/7 times as many cooks, it will take 7/8 the amount of time. (That's what "inversely proportional" means.)

  (7/8)(4 h) = 28/8 h = 3 1/2 h

It will take 8 cooks 3 1/2 hours to prepare the dinner.

What is the minimum number of binary bits needed to represent each of the following unsigned decimal integers? a. 65
professor190 [17]

Answer: N >/= 7 bits

Minimum of 7 bits

Step-by-step explanation:

The minimum binary bits needed to represent 65 can be derived by converting 65 to binary numbers and counting the number of binary digits.

See conversation in the attachment.

65 = 1000001₂

65 = 7 bits :( 0 to 2^7 -1)

The number of binary digits is 7

N >/= 7 bits

What is the interquartile range of 77 88 92 81 86 84 86 83 and how do you get it thx plz help
puteri [66]
To find the IQR you first need to write it in numerical order

77, 81, 83, 84, 86, 86, 88, 92


IQR is just Q3 - Q1

Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82

Q3 done the same process would be 87. 

87 - 82 = 5

IQR = 5
