Mathematics
1 answer:

There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

The 1st option is not a function because the inputs 9 and 10 have more than one output.

The 2nd option is not a function because the input 3 has more than one output.

The 3rd option is a function because each input only has one output.

The 4th option is not a function because the input 5 has more than one output.

Answer:

265.1 units²

Step-by-step explanation:

Area of circle:

3.14 × 12²

452.16

Side of the triangle:

s² = 12² + 12² - 2(12)(12)cos(120)

s² = 432

s = 12sqrt(3)

Area of triangle:

½ × s × s × sin(60)

½ × 432 × sqrt(3)/2

187.0614872

Shaded area:

452.16 - 187.0614872

Three poultry farms B1, B2, and B3 supply chicken eggs to the same local market. The market performs some quality testing on the
ipn [44]

Answer:

a. 0.58

b. 0.78

Step-by-step explanation:

a. The probability of egg come from B1 or B2

P(B1) = 3000/10000 = 0.3

P(B2) = 4000/10000 = 0.4

P(P1 ∪ B2) = 0.3 + 0.4 -(0.3)(0.4)

P(P1 ∪ B2) = 0.7 - 0.12

P(P1 ∪ B2) = 0.58

b. The probability that the market received an egg that is acceptable

P(received an egg that is acceptable) = P(B1 acceptable) + P(B2 acceptable) + P(B3 acceptable)

P(received an egg that is acceptable) = 0.80*3000 + 0.90*4000 + 0.60*3000 / 10000

P(received an egg that is acceptable) = 2400 + 3600 + 1800 / 10000

P(received an egg that is acceptable) = 7800 / 10000

P(received an egg that is acceptable) = 0.78

How do I find the correct slope on a graph?
-BARSIC- [3]

Answer:

To find the slope of a line from a graph, first choose 2 points along the line and write down the X and Y coordinates for each. Next, find the rise by taking the difference between the 2 Y coordinates. If the line slopes up as it moves to the right, the rise will be positive. If it slopes down, the rise will be negative.
