Answer:
6,138
Step-by-step explanation:
Given the following:
Vocalist needed :
First day (a) = 6
For subsequent days : number doubles
Using the relation. :
Sn = a(r^n -1)/(r -1)
Where a = first term = 6
r = common ratio = r3/r2 = r4/r3
Since number doubles after each consecutive day, then ; r = 2, n = 10
Sn = 6(2^10 -1)/(2 -1)
Sn = 6(1024 - 1) / 1
Sn = 6144 - 6
Sn = 6138
Answer:
Step-by-step explanation:
Add the 3/4 to cross it out on the left side and whatever you do to one side you do to the other side. so you add 3/4 or .75 on to 10 to get 10.75.
k-3/4=10
k=10.75
Subtract the 5/7 from the Z and subract it from -3 to get, -3.71.
Z+5/7=-3
Z=3.71
Subtract 9 from the left side and subtract 9 from the right side.
9+t/12=-3
t/12=-12
Then you would multiply by 12 from the left side and multiply by 12 from the right side.
t/12=-12
t=-144
Answer: slove it like i said
Step-by-step explanation:
Answer: The correct option is
(D) P(B, then G).
Step-by-step explanation: Given that we randomly draw marbles from a bag containing both blue and green marbles, without replacing the marbles between draws.
Also, B = drawing a blue marble and G = drawing a green marble.
We are to select the option that represents the probability of drawing a blue marble first and a green marble second.
Since we are drawing the second marble without replacing the first drawn marble, so the event is of the form
"first, then second."
So, the probability is written as P(B, then G).
Thus, The required probability is P(B, then G).
Option (D) is CORRECT.
