This question is just a question targeted towards puzzling the solver. It is infact a very easy problem. In the given question the information's provided should be very minutely watched. First information says that there is an unknown number. The problem revolves around this unknown number and various information's show that this number is always connected with the majority information's provided.
Let us assume the unknown number = x
Then
2x -4 = x - 10
2x - x = - 10 + 4
x = - 6
So the unknown number is -6.
Answer:
25/56
Step-by-step explanation:
Prob of white = 3/8
Probability of not white = 1 - 3/8
= 5/8
Second pick without replacement
Probability of white = 2/7
Probability of not white = 1 - 2/7
= 5/7
Total probability = 5/8 x 5/7
= 25/56
Answer:
what is the answer?
Step-by-step explanation:
Answer:
87.5%
Step-by-step explanation:
to write a percentage as a number you move the decimal to the left 2 times.
A1=2
a2=-8
a3=32
a4=-128
a2/a1=(-8)/2→a2/a1=-4
a3/a2=32/(-8)→a3/a2=-4
a4/a3=(-128)/32→a4/a3=-4
a2/a1=a3/a2=a4/a3=r=-4
an=a1*r^(n-1)
an=2*(-4)^(n-1)
The explicit rule for the nth term of the given sequence is an=2*(-4)^(n-1)
