The sizes of cans on a shelf are listed below. 18 oz, 8 oz, 16 oz, 20 oz, 20 oz, 16 oz, 12 oz, 8 oz what is the interquartile range of this list? a)2 b)6 c)9 d)12

Option C. 9

Step-by-step explanation:

To solve this question we will follow the following steps.

1).First we will arrange the data in ascending order.

8 oz, 8 oz, 12 oz, 16 oz, 16 oz, 18 oz, 20 oz, 20 oz

2).Now median of this arrangement of data will be

=

Median = 16

3).Now lower quartile of this sequence is 8, 8, 12, 16 and the upper quartile is 16, 18, 20, 20

4).Median of lower quatile =

5).Median of upper quartile =

6). Now we will subtract median of lower quartile from upper quartile to get the interquartile range of this list

Interquartile range = 19 - 10 = 9

Therefore Option C) 9 is the correct option.

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! : )
