 20% of the teachers are from district M

There are 50 teachers from district M, so bar M is 50 units tall.

Work Shown:

Let's add up the bar heights of the bars shown in the chart.

J+K+L+N = 50+80+30+40 = 200

So 200 teachers are from districts J,K,L, or N.

We're told that 250 total teachers attended. This must mean M = 50. We're effectively solving 200+M = 250.

So you'll need to draw a bar over M such that it is 50 units tall. This will complete the chart.

Because there are 50 teachers from district M, out of 250 total, we can then compute the percentage to get

50/250 = 0.20 = 20%

So 20% of the teachers are from district M.

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.

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
