Answer:
D There is an infinite number of solutions to the system of equations
Step-by-step explanation:
When you put the first equation in standard form by dividing it by 2, you get ...
x -2y = 4
When you put the second equation in standard form by dividing it by 8, you get ...
x -2y = 4
These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.
There is an infinite number of solutions.
The inputs are -3, -4, 8, and 7

Answer:
The probability of picking exactly 4 of the 6 numbers correctly is
Step-by-step explanation:
As order is unimportant, we have to calculate the different outcomes with combinations formula:
The total outcomes of picking exactly 4 of the 6 numbers is:
The probability of picking exactly 4 of the 6 numbers correctly is given by:
Total outcomes by picking 6 numbers from 1 to 42: 5245786
P(4 of the 6 numbers are correct)=
