Explanation A number is divisible by 5, if the last digit of the number is either 0 or 5. For a number to be divisible by 10, then the last digit of the number must be 0. So, any number divisible by 10 must be divisible by 5. That is 10 | x then 5| x where x is any integer. Consider the number 7 To determine (b) To justify: Whether if a number is not divisible by10, can it be divisible by 5.

Please help me organize the proof of the following theorem:

The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n = 65, find the probability of a sample mean being greater than 225 if μ = 224 and σ = 3.5. For a sample of n = 65, the probability of a sample mean being greater than 225 if μ=224 and σ = 3.5 is 0.0102 (Round to four decimal places as needed.)
