Determine whether the data are discrete or continuous. number of pixels in a smartphone screen.

It is a discrete data.

Step-by-step explanation:

Number of pixels in a smartphone is discrete data.

As we know that 'Discrete data' contains only integer value that can be counted.

Number of pixels is a finite value and cannot be sub divided meaningfully.

Since it is typically a whole number .

Hence, it is a discrete data.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
