Answer:
C. Independent, 49/1296
Step-by-step explanation:
A jar contains 12 red balls, 7 green balls, 10 white balls, and 7 yellow balls.
Total balls = 12+7+10+7
Total balls= 36
Two balls are chosen at random with replacement.
The probability that the both balls are green = probability of the first ball to he green * probability of the second ball to be green
The probability that the both balls are green= 7/36 * 7/36
The probability that the both balls are green= 49/1296
The probability that the both balls are green= 49/1296

Answer:
not enough information given
Step-by-step explanation:
as the rules say, we need at least 3 pieces of information :
2 angles and a side, or 3 angles (or there are other options like 2 sides and one angle or 3 sides).
but here we get 1 side and 1 angle. the shared point does not give us anything in that regard.
so, not enough information.
Answer:
To bring the submarine back to the sea level, it have to move 578 feet upwards
Step-by-step explanation:
Given:
Initially the depth the submarine dives = 657 feet below sea
The height the submarine moves up = 79 feet
To Find :
Change in its depth required to bring the submarine back to the sea level = ?
Solution :
In initially the Submarine will be at the depth of 657 feet below sea
when it goes up, the the depth reduces
657 - 79 = 578 feet
Now the submarine will be the depth of 578 feet
Now the submarine have to move 578 feet upwards to reach the sea level
, that the ladder is making with the ground, we are going to use a trig function that relates the adjacent side of our angle with the hypotenuse. That trig function is Cosine.
