Pakistani Indus River's annual flow is 58 cubic miles (243 cubic km) twice that of the Nile River

Explanation

The probability of the occurrence of an event lies between 0 and 1.

Explanation

Given the equation x - 1 = 0,

we can solve for x by isolating it on one side of the equation.

1. Equation:

x - 1 = 0

2. Adding 1 to both sides:

x - 1 + 1 = 0 + 1

3. Simplifying:

x = 1

Explanation

Number of subsets $=$$2^{}$${}^{}$$=$$2^{}$${}^{}$$=$$8$.

the number of possible subsets as 2^3 = 8.

Let's list all the subsets of set S:

- Subset 1: {} (the empty set)

- Subset 2: {a}

- Subset 3: {b}

- Subset 4: {c}

- Subset 5: {a, b}

- Subset 6: {a, c}

- Subset 7: {b, c}

- Subset 8: {a, b, c}

Explanation

A column matrix is a matrix with only one column,

and all the elements are arranged one below the other in a vertical line. 

Explanation

If a set A has m elements and set B has n elements,

then the number of functions possible from A to B is n^m.

Explanation

x + y^2 = 1 is symmetric with the  x-axis

Let's look at the graph of 

x + y^2 = 1 about the  x− and y-axis and the lines y = x and y = − x below.

graph{(x+y^2-1)(y-x)(y+x)=0 [-10, 10, -5, 5]}

X + y^2= 1 is symmetric with the x-axis 

Explanation

1. Center:

To check for symmetry, we first need to identify the center of the graph.

The equation is in the form of a circle, x^2 + y^2 = 1, which has its center at the origin (0,0).

2. x-axis symmetry:

A graph is symmetric about the x-axis if replacing y with -y in the equation does not change the equation.

Let's test this:

x^2 + (-y)^2 - x = 1

x^2 + y^2 - x = 1

As we can see, the equation remains the same, so the graph is symmetric about the x-axis.
