The mean = 2,000
s = Sigma ( standard deviation ) = 300
M - 2 s = 2,000- 2 * 300 = 2,000 - 600 = 1,400
M + 2 s = 2,000 + 2 * 300 = 2,000 + 600 = 2,600
Answer.
Useful life of light bulbs within 2 standard deviations of the mean is:
A ) Between 1,400 and 2,600 hours
Answer:
Step-by-step explanation:
The ordered pair is located on the boundary line of the graph of the inequality, and because the sign is "less than or equal to", the values on the boundary line are also included in the solution set.
Looking at this logically, we also see that it certainly possible for half the seats to be occupied by adults and half by children.
Answer:
A and B are independent events because P(AIB) = P(A).

<h2>

</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a given line segment can be found by using the formula
<h3>

</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-4, -9), (-6, -6)
The midpoint is
<h3>

</h3>
We have the final answer as
<h3>

</h3>
