Determine the size of sample space
Represent this with S
S is calculated by dividing the total number of kids by the number of selection.



<em>Hence, the sample space has a size of 4</em>
Answer:
its -26^14 i believe
Step-by-step explanation:
Answer:
3271
Step-by-step explanation:
so in the number there are four numbers
the 3 is in the thousands so it goes first
the 2 second
the 7 third
and the 1 last

-
9² = 12² + 15² - 2 (12) (15) cos (B)
81 = 144 + 225 - 360 cos(B)
81 = 369 - 360 cos (B)
360 cos (B) = 369 - 81
360 cos (B) = 288
cos (B) = 0.8
-
Answer: Cosine B = 0.8
-

-
12² = 15² + 9² - 2 (15)(9) cos (A)
144 = 225 + 81 - 270 Cos A
144 = 306 - 270 Cos A
270 Cos A = 162
Cos A = 3/5 or 0.6
-
Answer: Cosine Angle A = 3/5
Answer:
Surface area of the whole figure
Step-by-step explanation:
The surface area of the figure :
Surface area of the cylinder(excluding top)+Surface area of the cone(excluding bottom)
Radius of the cylinder=3 inch and Height of cylinder=13 inch
Surface area of the cylinder with one circular face

As, 

Surface area of the cone excluding base:

l= slant height=5 inch r= radius= 3 inch
Surface area of the cone =

Total surface area of the whole figure
