Answer:
x=4200, y=2700
Step-by-step explanation:
let x be first account
y the second
x+y=6900
0.03x+0.08y=342
solve by addition/elimination)
multiply first equation by 0.03
0.03x+0.03y=207 subtract from second
0.03x+0.03y-0.03x-0.08y=207-342
0.05y=135
y=2700, x=4200

Answer:
Step-by-step explanation:
We would assume that a randomly selected registered voter, x is classified as a conservative or not. It means that there are only 2 possible outcomes. Thus, it is a binomial probability distribution and the probability of success, p is that a randomly selected voter is classified as a conservative. Therefore,
p = 20% = 20/100 = 0.2
Number of trials, n = 10
Number of success, x = 6
The probability that six out of 10 would be conservatives is expressed as
P(x = 6)
Using the binomial probability calculator,
P(x = 6) = 0.0056
