Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of kids = 10
Number of kids in Team A = 5
Number of kids in Team B = 5
There are three kids in the group, Alex and his two best friends Jose and Carl.
So, number of favourable outcome is given by
Total number of outcomes is given by
So, the probability that Alex ends up on the same team with at least one of his two best friends is given by
Hence, the required probability is
Answer: d1 is 50, c2 is 21/25
Answer:
3 9/50
Step-by-step explanation:
3.18 is 3 18/100
Simplifying it further you get: 3 9/50
Answer:
f(7) = 16
Step-by-step explanation:
substitute x = 7 into f(x) , that is
f(7) = 3(7) - 5 = 21 - 5 = 16
Answer:
A. 6.32455 inch
B. 71.565°
C. 36.87°
Step-by-step explanation:
A. to find slant height we shall use Pythagoras theorem:
AC^2 = AB^2 + BC^2
AC^2 = 2^2 + 6^2
AC = 6.32455 inch ......... that's the slant height of the cone
B. here we have to find angle A, its where the line segment lies on the base
we use sin cos tan formula
opposite/ adjacent = tan (A)
A = tan^-1(6/2)
=71.565°
C. we have to find the angle where opposite both slant height meets, that's angle C.
as its a right angle triangle we can find half of C° = ( 180° - 90° - 71.565° ) =18.43494882°
So C angle shall be = 18.43494882° * 2
=36.87°
