Suppose that the probability of a success on a trial is 0.05. Find the probability of getting 2
successes in 100 trials.-this is a routine binomial distribution q
number of trials n = 100,
probability
years since 1991 and n(t) is measured in millions
What was the actual rat population in 1991 ?(not in millions)
What is the rat population going to be in the year 2002 ?-NOT in millions??? Im not s
Solve:
E = 1/2mv^2
Please explain it for me?
And this other one:
Clear the fractions. Do NOT solve:
(1/3)x + (1/12)x = (3/4)x - 2
and in addition to that, theres a question after that that says:
How to solve this?4/(x^2-3x+2) - 3/(2x^2-6x+1) +1 = 0
RESULT IS : X1=0,x2=3,x3,4=±i√11)/2-4/(x^2-3x+2) - 3/(2x^2-6x+1) +1 = 0
let 2x^2-6x+1 = Y, then
2*4/2*(x^2-3x+2) - 3/(2x^2-6x+1) +1 = 0
2*4/(
solve: (y-6)/(x+1)= 3/4 for y
Please show steps so that I can try to see and understand myself. I missed a week of math class due to having teeth surgically removed and am completely lost. But I do w
Can someone help me solve for x in this equation.
.0611 = X^2 / (1768-X) (1332-X)-.0611 = x^2 / (1768-x)(1332-x)
.0611(1768-x)(1332-x) = x^2
.0611(2354976-1768x-1332x+x^2) = x^2
.0611(2354976-3100x+
