Answer: The times within which 99.73% workers fall are 252.2 and 573.2 minutes.
Explanation:
It is known that to capture approximately 99.73% of the mass (area) of the normal distribution one has to consider +/- standard deviations from the mean.
The mean is 413 minutes and 1 standard deviation is 26.8 minutes. 6 standard deviations are 160.8 minutes.
Therefore the minimum time is 413-160.8=252.2 minutes and the maximum time is 413+160.2=573.2 minutes.
The times within which 99.73% workers fall are 252.2 and 573.2 minutes.
The first one is mode. The second one is mean. And lastly, the third one is median.
The angle relationship that best describes angles BAC and DAC is adjacent angles
<h3>What are adjacent angles?</h3>
Adjacent angles are two angles that have a common side and a common vertex but do not overlap in any way.
The common vertex of the angle BAE and FAC is A.
The angles share the same vertex and the same side.
Therefore, the angle relationship that best describes angles BAC and DAC is adjacent angles

D
An acute angle is less than 90 degrees
F(x) = 2x - 10
let y = f(x)
y = 2x - 10 solving for x.
y + 10 = 2x
2x = y + 10
x = (y + 10)/2
Recall f(x) = y. Implies x = f⁻¹(y)
<span>x = (y + 10)/2
</span>
f⁻¹(y) <span>= (y + 10)/2
</span>
So as well:
f⁻¹(x) <span>= (x - 10)/2</span>
