Answer:
Answer (B) and answer (D) apply
Step-By-Step explanation:
You can take the x and y values of the points and use them on the opposite axis, depending on how many times you would have to use them on the opposite axis you can determine how much rotation is needed (Every time you use the points on the opposite axis it is equivalent to 90 degrees).
Answer:
3.
Step-by-step explanation:
If its an AS it well have a common difference, so 3rd term - 2nd term should = 2nd term - first term:-
29 + x - (28 - x) = 28 - x - (15 + x)
2x + 1 = 13 - 2x
4x = 12
x = 3.
The sequence is
15 + 3, 28-3, 29 + 3
= 18, 25, 32
which is arithmetic with common difference 7.
Answer:
D) 7
Step-by-step explanation:
Let y = number of yellow marbles in the bag
For the first marble
P(yellow) = number of yellow marbles over total
=y/12
For the second draw, there are y-1 yellow marbles in the bag, and only 11 marbles left since we keep the first marble
P(2nd marble yellow) = (y-1)/11
The probability that the first and second marble are yellow when we keep the first marble is
y/12 * (y-1)/11 = 5/33
y * (y-1) 5
---------- = ----------
121 33
We can use cross products to solve
33 y(y-1) = 660
Divide each side by 33
y(y-1) = 660/33
y(y-1) = 20
Distribute
y^2 -y =20
Subtract 20
y^2 -y -20 =0
Factor
(y-5)(y+4) =0
Using the zero product property
y = 5 or y = -4
Since we cant have negative marbles
We have 5 yellow marbles
Since there are 12 marbles
12-5 =7
There are 7 green marbles
