Suppose a geyser has a mean time between eruptions of 77 minutes. Let the interval of time between the eruptions be normally distributed with standard deviation 25 minutes. What is the probability that a randomly selected time interval between eruptions is longer than 88 ​minutes?

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
