The value that is 2 standard deviations from the mean is; 130
<h3>What is Empirical Rule?</h3>
For this question, we will use Z-score and as such whether the value is below or above mean (shown by positive or negative sign) and by how much (times the standard deviation).
Thus;
Calculated value = μ + zσ
where;
μ is mean
σ is standard deviation
Hence, the value that would be +2 standard deviations from the mean is;
Calculated value = 100 + 2(15)
Calculated value = 130

Answer:
2. Stepford is the least consistent in daily temperatures because its standard deviation is the highest.
Step-by-step explanation:
Standard deviation is the average amount that each data point is from the mean. The lower the standard deviation is, the closer each data point is to the mean; this means it is more consistent if it has a low standard deviation.
Stepford has the highest standard deviation; this means it is the most variable, or least consistent.
Answer:
Step-by-step explanation:
x+5+5=x+10=Sam's age 2x+5+5=2x+10=Nina's age 2x+10=1.5(x+10) (In five years, Nina will be 1.5 times as old as Sam. 2x+10=1.5x+150.5x=5x=10x+5=152x+5=25.
Nina:25
Sam:15
Answer:
The answer is (1,-5). (i.e x=1 and y=-5).
