20+15x 40+5x company b would be cheaper after 3 hours
Answer:
811/16 i think
Step-by-step explanation:
Answer:
I would go with C only because you have the find the median of the lower half of the data set This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.
Step-by-step explanation:
Lower quartile (xL): 26.5
Median (xm): 37
Upper quartile (xU): 44.5
In this case or scenario,
the double-angle identity that should be used is the one for cosine. <span>
In totality, we shall need the following three trigonometric
identities to end up with the equality:
<span>1. cos (2a) = cos² (a) - sin² (a)
2. sin² (a) + cos² (a) = 1
<span>3. tan² (a) + 1 = sec²
(a)
<span>Using identities 1 and 2 on the left-hand side of the
equation, we get the following:</span>
1 + cos (2a) = 1 + cos² (a) - sin² (a) = 2 cos² (a) </span></span></span>
<span>
<span>Recalling that cos² (a) = 1 / sec² (a) and applying identity
3, we find the following:</span>
2 cos² (a) = 2 / sec² (a) = 2 / (1 + tan² (a)) </span>
Therefore giving us:
<span>2 cos² (a) = 2 / (1 +
tan² (a))</span>
