Answer:
angles J and N
Step-by-step explanation:
vertical angles are congruent angles that are vertically across from each other
angle j and angle n are both right angles and they are both vertically across from each other therefore A is your answer
Answer:
A) d = 25/π
Step-by-step explanation:
To find the diameter of a circle, refer to the circumference formula:
C = d (π)
25 = d (π)
25/π = d
d = 25/π
Answer:
Probability that they are the youngest is 0.000549
Step-by-step explanation:
Given
Number of students = 16
Selected students = 4
Let n = number of students
n = 16
Let r = selections
r = 4
We're interested in selecting 4 students out of 16; the keyword, selection means we're dealing with combination because order is not important.
So,
Solving for nCr
nCr = n!/((n-r)!r!)
16C4 = 16!/((16-4)!4!)
16C4 = 16!/(12!4!)
16C4 = 16 * 15 * 14 * 13 * 12!/(12!4!)
16C4 = 16 * 15 * 14 * 13 / 4 * 3 * 2 * 1
16C4 = 1820 ways
There are 1820 ways of selecting 4 students from a total of 1820.
Only one of these ways can the four of them be the youngest.
So, probability = 1/1820
Probability = 0.0005494506
Probability that they are the youngest is 0.000549 (approximately)
