THE ANSWER IS..... X1= -6 & X2=0
Let A = the event that the first ball is odd number
and B = the event that the second ball is odd number
In the beginning, there are 25 balls which contain 13 balls of odd numbers. So the probability for the first selection (as to expect you would draw a ball of an odd number) is
P(A) = 13/25
After the selection, the rule does not allow replacement. So, there are 24 balls left containing now 12 balls of odd numbers. So the probability for the second selection (as to expect you would draw also a ball of odd number) is
P(B) = 12/24 = 1/2
Multiplying the two probabilities obtains
P(2 odd numbers) = 13/25 * 1/2 = 13/50
Answer:
30°
Step-by-step explanation:
If chord AB subtends two arcs with measures in the ratio of 1:5, then the measure of minor arc is x and the measure of major arc is 5x. Thus,

Thus, the measure of the angle AOB is 60°. Consider isosceles triangle AOB (because AO=BO=radius of the circle). The angles adjacent to the base AB are congruent, thus

Since line CD is tangent to the circle,

Hence,

Answer:
4
Step-by-step explanation:
since y=mx+c
comparing the question with the above equation
