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.
3x -y ⩾ 6
3x - 6 ⩾ y
now, with inequalities, what we do is, we graph the line of 3x - 6 = y, and then we shade the "true region".
if we pick a point on say hmmm (4, 0), namely x = 4 and y = 0, we can plug that in the inequality and see what we get,
3(4) - 0 ⩾ 6
12 - 0 ⩾ 6
12 ⩾ 6
is 12 really greater or equals to 6? well yes, therefore, the point (4, 0) lies on the "true region", since it's true, 12 is indeed ⩾ 6, so, where that point is, we shade.
now, the ⩾ means equals to or greater, and therefore, since the values could also equal the boundary points, the line is a solid line, because it includes the line itself, as well as the shading.
check the picture below.
Ratio: 4:3
96/4 bird houses shows the number to connect the ratios, you get 24. Then do 24 times 3 ( because of 3 days ) to get 72 days.
Answer: 72 days
Answer: OPTION B.
Step-by-step explanation:
Given the following equation:
These are the steps to solve it:
<em>Step 1</em>
Add like terms on the left side of the equation:
<em>Step 2</em>
Apply Addition property of equality, which states that:
Then, we can add 25 to both sides of the equation:
<em>Step 3</em>
Applying the Subtraction property of equality, we can subtract from both sides:
<em>Step 4</em>
Applying the Division property of equality, we can both sides of the equation by 3. Then:
