Here is some information about 26 houses. a,b and c are all different numbers. Number of bedrooms:1,2,3,4,5.Number of houses:7,a, b,c,8.The median number of bedrooms is 3.5 Work out a possible set of values for a, b and c.

or

Step-by-step explanation:

Given

Required

Find a, b and c

Median is calculated as:

This means that the median is the average of the 13th and 14th item.

Since the median is (average of 3 and 4),

and:

This implies that c begins at 14

So, the number of houses bedrooms 4 and 5 is:

Also

---- sum of total frequency

Substitute

Since a, b and c are different, then

a and b cannot be 5 because

a and b cannot be 3 because

because b ends at 13

a

So, possible sets are:

Include c, we have:

or

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

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!
