Answer:
y=26 (no x ) the y int is 26 I believe
Step-by-step explanation:
I would guess that you would need to find the Least Common Multiple (LCM) of 99 and 24 first.
After listing out all of the multiples, you would have 792 be the LCM of 99 and 24. But since we need to find the integer value of n, in 99n (which means 99 x n), then we need to divide 792 by 99, which would be 8.
n = 8
This is a hypergeometric distribution problem.
Population (N=50=W+B) is divided into two classes, W (W=20) and B (B=30).
We calculate the probability of choosing w (w=2) white and b (b=5) black marbles.
Hypergeometric probability gives
P(W,B,w,b)=C(W,w)C(B,b)/(C(W+B,w+b)
where
C(n,r)=n!/(r!(n-r)!) the number of combinations of choosing r out of n objects.
Here
P(20,30,2,5)
=C(20,2)C(30,5)/(20+30, 2+5)
=190*142506/99884400
=0.2710
Alternatively, doing the combinatorics way:
#of ways to choose 2 from 20 =C(20,2)
#of ways to choose 5 from 30=C(30,5)
total #of ways = C(50,7)
P(20,30,2,5)=C(20,2)*C(30,5)/C(50,7)
=0.2710
as before.
Let's rewrite the given sequence :1/3, 1, 5/3, 7/3 . Notice that 1 =3/3, then
1/3, 3/3, 5/3, 7/3,...We also notice that the common difference d is equal to:
3/3 - 1/3 = 2/3 and 5/3 - 3/3 = 2/3 & 7/3 - 5/3 = 2/3
Hence this sequence is NOT A GEOMETRIC PROGRESSION but an ARITHMETIC PROGRESSION,instead with d = 2/3
