The only order pairs among the given options that represent a function is :
- (9 , -3) , (9 , -1) , (9 , -1)
Because : To be a function, every element of domain (x) can have only one unique value y, and if we get more than two values of y for same x, it isn't a function at all.
The sum of the equation is 5
Given:
Required:
To find the probability that the dart land will be in the shaded region.
Explanation:
Area of the circle is given by the formula:

Where r = radius
Thus the area of the circular region

The area of the square is given by the formula:

Thus the area of the given square

The probability of an event is given by the formula:

The probability that the dart land will be in the shaded region

Thus probability

Final answer:
Thus the probability that the dart land will be in the shaded region is 0.349.
X is 64 because the 32 is half of x. So, when it is half of x, you multiply it by 2. 32 x 2 =64 = x.
Using the expression 5x + 23, the answers are as follows:
1. 5 is the coefficient.
2. 2 is the base
3. 3 is the exponent.
4. X is the variable.
