Answer:
The expected amount earned by a waitress per evening is $95.83.
Step-by-step explanation:
At a local restaurant there are six rooms total; 1 is a "high roller" room and other 5 are normal rooms.
There are 6 waitresses working at the local restaurant.
The room assignments are made by fair random selection such that each waitress has an equal probability of being in the "high roller" room.
This implies that a waitress can be assigned any of the six rooms with probability, .
The tip earned by the waitress working in the "high roller" room is $200 and that for other rooms is $75.
So, the distribution of tips earned is as follows:
X: $200 $75 $75 $75 $75 $75
P (X):
The expected value of a random variable is given by:
Compute the expected amount earned by a waitress per evening as follows:
Thus, the expected amount earned by a waitress per evening is $95.83.
X+(x+2)=144
2x+2=144
2x=142
x=71
the two consecutive odd integers are 71 and 73
Answer:
Option 3rd is correct
No,
she should have added and and compared that to
Step-by-step explanation:
In a right angle triangle, we use Pythagorean theorem.
Pythagorean theorem states that
the sum of the squares of two sides must equal the square of the third side(the side facing the right angle).
i.e,
Given a triangle with side lengths 6, 10, and 8.
If we square all the given sides, we get;
,
It can be seen that the sum of 36 and 64 is 100
⇒
which satisfies the Pythagorean theorem.
⇒ The triangle is right-angled with the side lengths 6 units and 8 units forming the right angle and the side length 10 units being the hypotenuse.
Therefore, her answer is incorrect, she should have added and and compared that to
