Population of 10,000 shellfish are approximately normally distributed with mean length of 10 cm and standard deviation 0.2cm. what length corresponds to the top 10% of shellfish lengths?

10.26cm

Step-by-step explanation:

With 10,000 shellfish approximately normally distributed with mean length of 10 cm and standard deviation 0.2cm, we can do a reverse normal probability to find out the length that corresponds to the top 10% (or larger than 90%) of the shellfish length:

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
