Answer:
P( second green | first green) = 1/3
Step-by-step explanation:
There are 7 marbles in the jar in total
After the first pick, given the marble removes is green marbles, how many green marbles are there left in the jar? How many marbles are there left in the jar?
Green marbles left: 2
Marbles left: 6
Using the multiplication law of probability,
P(A∩B) = P(A) x P(B|A)
P(second green | first green) = P(second green and first green) / P(first green)
P(second green and first green) = 3/7 x 2/6 = 1/7
P(first green) = 3/7
∴(1/7) / (3/7) = 1/3
Thus, we come up to the conclusion P( second green | first green) = 1/3

Solve using substitution. I know that the answer is (1,1), but I have to show my work and I forgot how to do it.
If y = -x + 2, then substituting this into the first equation lets you solve for x :
x + 4y = 5
x + 4 (-x + 2) = 5
x - 4x + 8 = 5
-3x = -3
x = 1
Now solve for y :
y = -x + 2 = -1 + 2 = 1
So the solution is indeed (x, y ) = (1, 1).

please answer this quickly
Answer:
C. 5x + 11 = 36
Step-by-step explanation:
You can see in the diagram that there are 5 x variables and eleven which make up the total diagram that says 36 so it would have to be 5x+11 = 36
Answer:
5x + 11 = 36
Step-by-step explanation:
Looking at the tape diagram, if you count the x, you have 5x and then you have 11. So it would refer to as 5x + 11 and the total of the tape diagram is 36. So it would be :-
5x + 11 = 36
Hope this helps, thank you :) !!

The corporate office building is 50m high and angle of elevation at top of building is 52° when seen from a point on level ground. The distance between point and foot of the building is
Answer:
39.06 m
Step-by-step explanation:
Given that,
Height of the building, h = 50 m
The angle of elevation at top of building is 52° when seen from a point on level ground.
We need to find the distance between point and foot of the building. Let the distance be d. Using trigonometry to find it. So,
[tex]\tan\theta=\dfrac{P}{B}[/tex]
Where
P is perpendicular
B is base.
So,
[tex]\tan\theta=\dfrac{h}{d}\\\\d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{50}{\tan(52)}\\\\d=39.06\ m[/tex]
So, the distance between point and foot of the building is 39.06 m
Applying the trigonometry ratio, TOA, the distance between the point and the foot of the building is: 39.1 m.
Recall:
SOH CAH TOA are the common trigonometry ratios that can be used to solve a right triangle.The information of the building has been sketched in the diagram shown in the image attached below. It shows a right triangle.
The distance between the point on the ground and the foot of the building = x (adjacent)Reference angle (∅) = 52°Opposite side = 50 mApply the trigonometry ratio, TOA:
tan ∅ = opposite/adjacent
Substitutetan 52 = 50/x
x = 50/tan 52
x = 39.1 m
Therefore, applying the trigonometry ratio, TOA, the distance between the point and the foot of the building is: 39.1 m.
