The following table represents the highest educational attainment of all adult residents in a certain town. If a resident who has only completed high school is chosen at random, what is the probability that they are aged 50 or over? Round your answer to the nearest thousandth

0.067

Step-by-step explanation:

The table has rows giving the degree and columns giving their ages.

We want probability of Only High School and aged 50+.

The first row is "high school only". We want this.

The 4th column is "Age 50 & over". We want this.

The intersection of 1st row and 4th column is what we want. That number of people is:

1206

The total number of residents is the right-bottom most cell, which is 18,122

Hence, the probability would be:

1206/18,122 = 0.0665

Nearest thousandth rounding is 3 decimal places, so the answer is:

0.067

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.

have a nice day!
