From the 68-95-99.7 rule we know that for a variable with the standard normal distribution, 68% of the observations fall between -1 and 1 (within 1 standarddeviation of the mean of 0), 95% fall between -2 and 2 (within 2 standard deviations of the mean) and 99.7% fall between -3 and 3

So in other words, I think what would fill in that blank is 2

The sum of 2 numbers is 48 and their difference is 24

Artemon [7]

Answer:

The numbers are 12 and 36

Step-by-step explanation:

x + y = 48

x - y = 24

Add y to both sides of the equation

x = 24 + y

Substitute new value for x into first equation

24 + y + y = 48

Add y's together

24 + 2y = 48

Subtract 24 from both sides of the equation

2y = 24

Divide both sides of the equation by 2

y = 12

48 - 12 = 36

The numbers are 12 and 36

Hope this helps :)
