Answer:x-24
Step-by-step explanation:
Solve for xby simplifying both sides of the equation, then isolating the variable.
Answer:
uhh I thought there were only 8 BAHAHA
Answer:
real number and rational number
Step-by-step explanation:
I infer that by number set you mean what kind of number it is. It is real because it is -3.8 and rational because it is terminating. It is not a integer, whole number, or natural number because -3.8 is a decimal
Let steph score be x
Then kyrie score is 2x-5
Sum of the two scores is 55
Therefore x+2x-5=55
3x-5=55
3x=60
x=20
Therefore steph score is 20
And kyrie score is 2(20)-5
40-5=35
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.
