Answer:
1. 94.25 is the surface area, 94.25 to 56.55 is the ratio of surface area to volume
2.138.23 is the surface area 138.23 to 113.1 is the ratio of surface area to volume
Answer:
D
Step-by-step explanation:
The mean will be the very middle of the distribution, which is at 66. So we know that a and c are wrong.
The standard deviation is the distance between those bars, like 70 and 74. 74-70 = 4, so the standard deviation is probably around 4.
That means the answer is D.
Answer:
Step-by-step explanation:
a) P (June) = 7/15
b) P (Angad) = 8/15
Answer:
Step-by-step explanation:
sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
cos² x + sin² x = 1
