Answer:
99.7%
Step-by-step explanation:
Bell shaped curve by empirical rule is that if the standard deviation from the mean (left to right) is 1 deviation then about 68% of the data is in that range if it’s 2 standard deviations away then it’s 95% and 3 deviations away is 99.7%
142-100=42=3(14)
100-58=42=3(14)
Therefore the data is three standard deviations from the mean and this there is 99.7% of the data in this range.
Answer:
Step-by-step explanation:
For example, we'll use this quadratic equation.
To understand how to plug it into the formula we need to know what each term represents.
So the equation above would be put into the formula like this.
Then we would solve
Now, the equation will branch off into one that solves when addition and one when subtraction.
So x={-3, -2} (-3 and -2)
Answer:
113
Step-by-step explanation:
96+17=113
