We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.
The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36
The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55
55 * 36 = 1980 different groups in the committee
Maybe you can try graphing it if the graph does not have any x-intercepts than it has no real roots
Answer:
i believe it is C 7,24,25
Step-by-step explanation:
good luck
A. since they choose 4 people to form the committee and all the people chosen are teachers
from 5 teacher, we choose 4, 5C4
and
from 20 parents, we choose none, 20C0
5C4*20C0= 5
b. from 5 teacher choose 2, 5C2
and
from 20 parents choose 2, 20C2
5C2 * 20C2=1900
c.all parents
from 5 teachers choose 0, 5C0
and
from 20 parents choose 4, 20C4
5C0 * 20C4= 4845
d. from 5 teacher choose 1, 5C1
and
from 20 parents choose 3, 20C3
5C1 * 20C3= 5700
Answer:
44.44°
Step-by-step explanation:
A tower that is 101 feet tall casts a shadow 103 feet long. Find the angle of elevation of the sun to the nearest degree.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = ?
Opposite = Height of the tower = 101 feet
Adjacent = Length of the shadow = 103 feet
Hence
tan θ = 101/103
θ = arc tan (101/103
θ = arctan(0.9805825242718447)
θ = 44.438294667°
Approximately to the nearest degree = Angle of elevation = 44.44°
