Answer:
1/2= 5/10
5/10 - 3/10 = 2/10 or 1/5
so planet X is 1/5 of a light-year closer
Step-by-step explanation:
<span>If there were 2.33 x 10^6 cell phone subscriptions in 2006, the number of subscriptions in standard form equals 2,330,000. To translate 2.33 x 10^6 into standard form simply requires moving the decimal six places to the right. Zeroes must be added for the places where numbers do not exist until the decimal point has been moved six places.</span>
<span>x(x−3)=54
x^2 - 3x - 54 = 0
(x - 9)(x +6) = 0
x - 9 = 0 so x= 9
x + 6 = 0 so x = -6
</span><span>
x = 9 (length)
so width = x - 3 = 9 -3 = 6
</span>answer
<span>length = 9
double check
Area = LxW = 9x6 = 54
</span>
Answer:
I think it is D
Step-by-step explanation:
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
