The period of cos is 2π
so the period of cos(4x + π) is 2π/4 = π/2
cos(4x + π) = -cos4x => <span>-3 cos(4x + π) + 6 = 3cos4x + 6
phase shift may be [-</span>π/4,π/4]
amplitude is [-3,3]
I'm guessing the length is 4, the width is 6 and the height is 2.8,
67.2 is the answer and the units are m^3

Answer:</h3>
The reasoning is correct. The ratio of number of bulbs tested to defective bulbs is always 14 to 1.
<h3>
Step-by-step explanation:</h3>
We generally expect industrial processes to produce defects at about the same rate, meaning the proportion of defective product is generally considered to be a constant. Here, the proportion of defective bulbs is ...
... 1/14 = 2/28 = 6/84
so we expect it will be also 24/336. That is, the ratio of the number of bulbs tested to defective bulbs is expected to remain constant at about 14.
