Explain why (-8) is not a solution to the equation x³=512

1 answer:

6 0

-8 is not a solution to 512 because when you multiply 2 negative numbers together it becomes positive, but you're multiplying it three times. so - 8 * -8 = 64 but if you multiply -8 again the solution will be a -512 not a positive 512

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. n equals 125n=12

sesenic [268]

<span>This is a matter of knowing the formulas involving the binomial distribution: Mean = n*p = 125*0.46 = 57.5
Variance = n*p*(1-p) = 125*0.46*(1-0.46) = 125*0.46*0.54 = 31.05
Standard Deviation = sqrt(Variance) = sqrt(31.05) = 5.572252686</span>
