Answer:
-1
Step-by-step explanation:
in negative numbers, it goes the opposite of positive numbers
Given:
Two numbers and 2.
To find:
How many are in 2.
Solution:
Let x be number of in 2.
Divide both sides by .
Therefore, required multiplication equation is and the required division equation is .
What values are two standard deviations above and below the mean?
The values that are two standard deviations above and below the mean are 690 and 262, respectively
The given parameters are:
Mean = 476
Standard deviation = 107
The values above and below the mean are calculated using:
In this case n =2.
So, we have:
The value above is:
x = 476 + 2 * 107 = 690
The value below is:
x = 476 - 2 * 107 = 262
Hence, the values that are two standard deviations above and below the mean are 690 and 262, respectively
