Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
A <u><em>circumscribed angle</em></u> is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so
Find the measure of angle BAC
In the right triangle ABC
substitute given value
Find the measure of angle BAD
Find the measure of minor arc BD
we know that
-----> by central angle
therefore
It is given that there are 41 males and 48 females in the small school.
So, the number of ways a male student can be chosen from 41 males is
Likewise, the number of ways a female student can be chosen from 48 females is .
Thus, the total number of ways in which 2-person combinations are possible to represent the student body at the PTSAC meetings will be given by:
Answer:
C
Step-by-step explanation:
Now there are 6+4+8+1+1=20 dads in the Dads Club.
Fewer than 3 children have
- 1 child - 6 dads
- 2 children - 4 dads.
So, 6+4=10 dads have fewer than 3 children.
The probability that the dad of Dads Club has fewer than 3 children is
The probability that the next dad to join Dads Club has fewer than 3 children is reasonable to be 50%.
Answer:
The answer is B
