1 of 6 The length of each side of a square is 6.1 cm rounded to 1 decimal place. Write the error interval for the perimeter, p ,
arsen [322]

The error interval of the perimeter is 6.1 cm ≤ p < 6.15 cm

<h3>How to determine the error of interval?</h3>

The perimeter is given as:

P = 6.1 cm to 1 decimal place

The smallest number that can be approximated to 6.1 is 6.05, while the largest number is less than 6.15

This means that the interval is:

6.1 cm ≤ p < 6.15

Let x and y be any numbers at all with x ≤ y. Show that the number of integers between x and y is [y] - [x] +1.That is show that
ddd [48]

Answer:

the explanation is given below.

Step-by-step explanation:

  • Here what is applied is assumption of range of values of number from say 1 - 100
  • In total, i stopped at 100 on the dot.

from this, the lowest number is 1 and the highest number is 100

  • hence the range of the numbers = Difference between Highest and Lowest
  • range = 100 - 1 = 99, the 99 gotten as the range is indicative that a number has been missing.

  • In order to make up the 100, an integer is added to the difference = 99, i.e 99 is added to 1 to make up the 100.

  • Furthermore, if 0 is exclusively out when numbers are counted up 100 with 0 inclusive, in such case, the first and last number are excluded from the counting. as such the integers will be {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.........., 99} since both 0 and 100 are not included.

  • Here, if we try to get the range = highest - lowest = 99 - 1 = 98, it implies that to make up the 99, an integer is added to the result of the difference = 98+1 = 99

  • As such, the number of integers between two numbers is the difference between the highest and the lowest number plus 1 i.e highest - lowest + 1 = y - x +1 = (the floor of y) - ( the ceiling of x) + 1
