$\frac{y-y}{x-x}$ =gradient
$\frac{7+3}{-2+4} = 5$
Perpendicular gradient therefore is $\frac{-1}{5}$

With this info, y-y1=m(x-x1)
5(y-8)=-1(x-6)
5y-40=-x+6
5y=-x+46
$y= \frac{-x}{5} + 9.2$

If the measure of angle 5 is (11 x minus 14) degrees and x = 6, which expression could represent the measure of angle 2? 3 lines

ella [17]

Answer:

(A) (8 x + 4) degrees

Step-by-step explanation:

$m \angle 5 =(11x-14)^\circ\\x=6\\m \angle 5 =(11(6)-14)^\circ=(66-14)^\circ=52^\circ\\m \angle 5 =m \angle 2$ (Vertically Opposite Angles)$

Out of the options, the one which gives a result of 52 degrees could represent the measure of angle 2.

$(A)(8 x + 4)^\circ=(8(6) + 4)^\circ=(48+4)^\circ=52^\circ\\(B)(9x+2)^\circ=(9(6) + 2)^\circ=(54+2)^\circ=56^\circ\\(C)(20x + 8)^\circ=(20(6) + 8)^\circ=(120+8)^\circ=128^\circ\\(D)(18 x + 20)^\circ=(18(6) + 20)^\circ=(108+20)^\circ=128^\circ$

We can see that only Option A gives a result of 52 degrees. Therefore, it can represent the measure of angle 2.

200 is the median (50%) of the data represented in the box plot. The fraction of the books has 200 or fewer pages is: 1/2.

<h3>What is the Median of a Data in a Box Plot?</h3>

In a box plot, the median is indicated as the value marked by the vertical line that divides the rectangular box of the box plot.

The median is the middle of the data and represents the 50th percentile. That is 1/2 the data.

In the box plot given, 200 pages is the median. Therefore, the fraction of the books that have 200 or fewer pages is: 1/2.
