Based on the bar graph shown below, the 25th percentile is located in which interval?
a: 0 - 5
b: 6 - 10
c: 11 - 15
d: 16 - 20

B: 6 - 10

Step-by-step explanation:

We have been given a bar graph and we are asked to find 25th percentile in located in which interval.

Let us find total number of data points by adding the heights of all bars together.

Now let us find 25% of 34.

So 9th data point will be close to 25th percentile as it has 8.5 data points below itself.

Let us see 9th data point will falls in which interval.

We can see from our bar graph that interval 0-5 contains 5 data point and data points between 5 to 11 lies in interval 6-10, therefore, option B is the correct choice as 9 lies between 5 and 11.

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! : )
