Answer:
45 DOLLARS
Step-by-step explanation:
For these kind of problems, write an equation to figure out the answer.
55 + 2x = 145
x represents the bag cost
145 is the shoe cost
Take out the constant, which is 55, from both sides. A constant is a useful term you should learn.
The result is: 2x = 90
Divide 2x by 2, to get x, which is the bag cost, by itself.
Result: x= 45
Since x is the bag cost, the bag costs 45 dollars

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.
