A jar contains five red marbles and three green marbles. A marble is drawn at random and notreplaced. A second marble is then drawn from the jar.1) Find the probability that the first marble is red and the second marble is green.
2) Find the probability that both marbles are red.
3) Find the probability that both marbles are the same color.

i dont understand how to find 2 & 3, can someone explain please? thank you

4. The triangles are similar. If QR = 9, QP = 6, and TU = 19, find TS. Round to the nearest tenth.A. 16

B. 28.5

C. 2.8

D. 12.7

Answers

Set up a proportion since the two triangles are proportional.

QP/TS= QR/TU
6/TS= 9/19
cross multiply
(6*19)= (9*TS)
114= 9TS
divide both sides by 9
12.666666= TS
round up to the tenths decimal place
12.7= TS

ANSWER: D) 12.7 is TS

Hope this helps! :)

The correct answer is ;
QR=9
QP=6
TU=19
TS=?
Okay so the triangles are kindred, now the equation can be made
9/16=6/x
So now we are going to cross multiply
9x=114
Now divide both sides by
912 2/3
Your answer is:
TS=12.6 the correct answer is D.12.7

What is the slope of a line perpendicular to the line whose equation is 2y=-6x+8 1)-3
2)1/3
3)1/6
4)-6

Answers

2y=-6x+8

First, the slope of any equation, is always the coefficient with the variable "x".

So, the slope for this line, is -6x.

To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.

2y=-6x+8

y=-3+4

Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.

And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to 1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.

The answer is 2) 1/3.

Your supposed to get Y by its self. So do this- (-6x+8)/2You should get y=-3x+4So the slope would be -3 of the original line.The perpendicular slope would be the reciprical and opposite sign of it, so it should be 1/3. hope this helps
