Whatever you do to the numerator you must do to the denominator so 3 goes into 42 14 times so 3x14=42 2x14=28 so 2/3is equivalent to 28/42

Find the ratio in which the line joining the points (2, 4, 16) and (3, 5, -4) is divided by the plane 2x – 3y+ z+ 6 = 0. Also fi

Nastasia [14]

Answer:

Step-by-step explanation:

let the plane intersects the join of points in the ratio k:1

let (x,y,z) be the point of intersection.

$x=\frac{3k+2}{k+1} \\y=\frac{5k+4}{k+1} \\z=\frac{-4k+16}{k+1} \\\because ~(x,y,z)~lies~on~the~plane.\\2(\frac{3k+2}{k+1} )-3(\frac{5k+4}{k+1} )+\frac{-4k+16}{k+1} +6=0\\multiply~by~k+1\\2(3k+2)-3(5k+4)+(-4k+16)+6(k+1)=0\\6k+4-15k-12-4k+16+6k+6=0\\-7k+14=0\\k=2\\x=\frac{3*2+2}{2+1} =\frac{8}{3} \\y=\frac{5*2+4}{2+1}= \frac{14}{3} \\z=\frac{-4*2+16}{2+1} =\frac{8}{3}$

point of intersection is (8/3,14/3,8/3)

and ratio of division is 2:1

Probability scenarios?

velikii [3]

Here are some probability scenarios.

- Flipping a coin and seeing if it is heads or tails.

- Thinking to yourself: "Is it going to rain or hail?"

- Spinning a spinner and seeing what color it lands on.

- Probability in winning the lottery.

- Having 5 pairs of black shoes and one pair of yellow shoes.

The probability of picking the yellow shoe is 1/5.

There are lots of more examples out there!
