Answer:
(c)
Step-by-step explanation:
As given in the statement, we have:
Out of 4 games pieces, 1 is winner.
Probability to win =p=
Jeff has game pieces = n = sample size = 4
As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :
Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)
put n = 4, p =
P (X = 1) =
P =
Which is the probability that he wins exactly 1 prize and is option c.
Answer:
29730 voters
Step-by-step explanation:
so:
in 2017- 16/100=0.16 x 29,000=4640 so 29,000-4640=24360 voters
in 2019-22/100=0.22 x 24369=5361.18 so 24369+5361.18=29730.18 voters
I hope this helped

Answer: Arc CE measures 62 units
Step-by-step explanation: What we have in the question is a circle with two secants ABC and ADE. The two secants have been extended such that two arcs have been formed which are, major arc CE (that is, 4x - 10) and minor arc BD (that is 26).
When you have a circle with two intersecting secants, the angle x (that is angle CAE) is derived as half of the difference of the two intercepted arcs. That is;
Angle x = 1/2 [CE - BD)
Angle x = 1/2 [ (4x - 10) - 26]
Angle x = 1/2(4x - 36)
Cross multiply and we now have
2x = 4x - 36
Collect like terms and we now have
36 = 4x - 2x
36 = 2x
Divide both sides by 2
18 = x
Having calculated x as 18, where arc CE equals 4x - 10, then substitute for the value of x.
CE = 4(18) - 10
CE = 72 - 10
CE = 62
