They bought 8 orchestra seats and 6 mezzanine seats.
Step-by-step explanation:
Cost of one orchestra seat = $42
Cost of one mezzanine seat = $25
No. of people = 14
Amount spent = $486
Let,
x be the number of orchestra seats
y be the number of mezzanine seats
According to given statement;
x+y=14 Eqn 1
42x+25y=486 Eqn 2
Multiplying Eqn 1 by 25;
Subtracting Eqn 3 from Eqn 2 to eliminate y;
Dividing both sides by 17
Putting x=8 in Eqn 1
They bought 8 orchestra seats and 6 mezzanine seats.

Answer:
5/9
Step-by-step explanation:
From the information, 8 are more than 6 feet tall and 7 have good aim.
Therefore, the probability that the coach would randomly pick a player over 6 feet tall or a player with a good aim will be:
= 8/27 + 7/27
= 15/27
= 5/9
<span>Let's first set the two surge protectors as p and q. In order to solve this question we would also need another variable: the probability x of working correctly when a voltage surge occurs.
So, the probability that the voltage surge will not damage the TV is: 1 - 0.06^2 divide by x^2.</span>

Step-by-step explanation:
Answer: The ratio of protein bars to water bottles will be 4:3.
Explanation:
Since we have given that
Number of protein bars = 20
Number of water bottles = 15
We need to calculate the ratio of protein bars to water bottles which is given by
So, the ratio of protein bars to water bottles will be 4:3.
