Answer:
The cost for each movie is $2
The cost for each video game is $6.5
Step-by-step explanation:
Let
x-----> the cost for each movie
y-----> the cost for each video game
we know that
5x+2y=23 -----> equation A
3x+8y=58 -----> equation B
Solve the system of equations by graphing
Remember that
The solution of the system of equations is the interception point both graphs
The solution is the point (2,6.5)
see the attached figure
therefore
The cost for each movie is $2
The cost for each video game is $6.5
Answer:
Probabilty= 4.171. *10^-4
Step-by-step explanation:
bridge is made up of 13 cards
probability that a bridge chosen at random contains
6 of one suit, 4 of another, and 3 of another
Probabilty of 6 = 13C6
Probabilty of 4 = 13C4
Probabilty of 3 = 13C3
Then total= 53C13
Probabilty =( 13C6*13C4*13C3)/53C13
Probabilty=( 1716*715*286)/53C13
Probabilty= 4.171. *10^-4

Answer:
True statements are:
C. The water level decreased by \abs{-12} inches.
E. The water level experienced a change of 12 inches.
Step-by-step explanation:
A change in the water level of a swimming pool is recorded a -12 inches.
Now, from the above statements, we have to choose options statements that are true.
A. The water level increased by 12 inches. This is false.
B. The water level increased by \abs{-12} inches. This is also false.
C. The water level decreased by \abs{-12} inches. This is a true statement.
D. The water level has a height of -12 inches. This is again a false statement.
E. The water level experienced a change of 12 inches. This is a true statement. (Answer)
