Final answer:
In Spanish numbers, the conjunction 'y' is located between tens and ones place values for numbers 31 to 99, as in 'treinta y uno' for 31 and 'cuarenta y dos' for 42.
Step-by-step explanation:
In the context of Spanish numbers, the letter 'y' is used as a conjunction and is found between tens and ones when they are combined to create numbers from 31 to 99.
For instance, the number 31 in Spanish is written as 'treinta y uno,' and the number 42 is 'cuarenta y dos.' Therefore, the 'y' is located between the units representing the tens place and the ones place in these numbers.
In statistics, when a distribution follows a normal distribution, about 95 percent of the values fall within two standard deviations of the mean.
This means that about 95 percent of the 'y' values lie between the mean minus two standard deviations and the mean plus two standard deviations.
