Answer:
The second one
Step-by-step explanation:
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:
top right
Step-by-step explanation:
Answer:
below
Step-by-step explanation:
for f(x) insert the x into the equation.
example:
f(-6) → -(-6+2)^2
follow pemdas
p: -(-4)^2
e: -(16) because -4 times -4 is 16.
m: -(16) → -16
Do that for the rest of the first table. As for the inverse table, f(x) and x will just switch spots. so (-6,-16) will become (-16,-6)
Answer:
σX = 3161
Step-by-step explanation:
The standard deviation is the square root of the multiplication of each probability multiplied by the squared difference between the values and the mean.
In this question:

Rounding to the nearest dollar, σX = 3161
