Answer:
The probability that the all three votes are Democrats
P(X=3) = 0.1038
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the all voters are democrats
The probability that the all voters are democrats
p = 47% =0.47
q = 1-p =1-0.47 = 0.53
<u><em>Step(ii):-</em></u>
Let 'X' be the random variable in binomial distribution
The probability that the all three votes are Democrats
P(X=3) = 0.1038
n=3 and r=3
P(X=3) = 0.1038
<u>Final answer:-</u>
The probability that the all three votes are Democrats
P(X=3) = 0.1038

3x^2 = 7x - 3
3x^2 - 7x = -3
x^2 - 7/3x = -1
x^2 - 7/3x + 49/36 = -1 + 49/36 = 13/36
(x - 7/6)^2 = 13/36
x - 7/6 = + or - sqrt(13)/6
x = 7/6 + or - sqrt(13)/6
x = (7 + or - sqrt(13))/6
I think it would be D hope it helps!!!
Answer:
\sqrt{7}i or -\sqrt{7}i
Step-by-step explanation:
square root both sides of the equation
since you can't sqrt a negative number, you substitute sqrt of -1 to i
Which gets the answer.
Answer:
An equation would look something like 14+9a=86
$14 initial fee plus $9 per hour for a total of $86
So subtract 14 from each side of the equation to leave you 9a=72
Divide each side by 9, leaving x=8
8 hours
