Answer:
x = 6; 6 weeks
Step-by-step explanation:
Hi!!
Okay, so here is the equation needed to solve:
85.00 = 25.00 + 12.00x
Subtract 25 from both sides
85 -25 = 25 - 25 + 12x
Then, you get:
55 = 12x
Divide 55 by 12
55/12 =x
so x = 6
Hope this helps!
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
