Possible outcomes: 10C4 = 210 ( combinations - we choose 4 of 10 people )
Favorable outcomes: ( 2C1 ) · ( 8C3 ) = 2 · 56 = 112
Probability : 112 / 210 = 0.5333 ( or 53.33 % ).
Answer:
two
Step-by-step explanation:
The two functions met at two points
Answer:
Step-by-step explanation:
I = -425x^2 + 45,500(x) - 650,000
x = 40
I = -425(40^2) + 45,500(40) - 650,000
I = -425(1600) + 1,820,000 - 650,000
I = -680,000 + 1,820,000 - 650,000
I = 1,820,000 - 1,330,000
I = 490,000 <===
There are many solutions. Choose any 'x', and then choose 'y' which is greater than 7 and greater than the double of 'x'.
When writing the ordered pair, remember that 'x' comes first.
Some examples: (0,8), (1,10), (-3,9), etc.
You can interpret this graphically. The points that solve 'y>2x' are those above the line 'y=2x', and the solutions to 'y>7' are those above the line 'y=7' (which is an horizontal line). Hence the solution to the system of inequalities is the intersection of those two regions. Have a look at the illustration:
