a survey was taken of children between the ages of 3 and 7. let a be the event that the person has 2 siblings, and let b be the event that the person does not have a pet.

which statement is true about whether a and b are independent events?

a) a and b are independent events because p(a∣b) = p(a) = 0.18.
b) a and b are independent events because p(a∣b) = p(a) = 0.4.
c) a and b are not independent events because p(a∣b) = 0.4 and p(a) = 0.18.
d) a and b are not independent events because p(a∣b) = 0.18 and p(a) = 0.4.

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.
