Answer: -47/36
Step-by-step explanation:
3/2y-14/3x
as x=3 and y=6
3/2(6)-14/3(3)
3/12-14/9
1/4-14/9
9-56/36
-47/36
Answer:
a. 720
b. 0.3
Step-by-step explanation:
a.
Three balls are selected at random without replacement.
First ball can be selected in 10 ways
Second ball can be selected in 9 ways
Third ball can be selected in 8 ways
Thus, there are 10×9×8 =720 different ways of selecting three balls.
b.
There are three cases that satisfy this condition
- first ball picked is 5, the others are not
- first ball is not 5, second is 5, third is not
- first and second ball is not five, third ball is 5
Each probabilities are:
Thus, one of the balls selected is the number 5 is then

See below (I hope this helps!)
Step-by-step explanation:
When rotating a point 90° about the origin, the coordinates (x, y) become (y, -x) so we can apply this rule to points G, H, and I.
Therefore:
G(-1,3) → G'(3, 1)
H(-4,0) → H'(0, 4)
I(3, -2) → I'(-2, -3)
Hi,
The answer is 26th.
The way you get that is you add 25 + 1 = 26.
Hope this helps.
