Suppose a nonnegative random variable X has mean 50. a) Suppose that we know Var(X) = 25. Find a bound for P(X≥95P(X≥95 or X≤5)X≤5). P(X≥95P(X≥95 or X≤5)X≤5) ≤≤ b) Suppose that we also know that X is binomially distributed. Calculate the precise probability P(X≥95P(X≥95 or X≤5)X≤5). The precise probability P(X≥95P(X≥95 or X≤5)X≤5) is c) Compare the upper bound from (a) with the precise value of P(X≥95P(X≥95 or X≤5)X≤5) from (b). Type "IS" if the precise value is consistant with the bound and "IS NOT" if it is not. Then type "GREATER" if the precise value is greater than the upper bound and "LESS" if it is less. The exact value consistant with the bound from Chebyshev's Theorem estimated above. However, the exact value is much than the upper bound.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

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! : )
