217

Step-by-step explanation:

The mean or average is calculated by taking the sum or addition of the data points, and dividing by the number of data points. This is known as a sample of data because it is a subset of data.

In simple terms, add all the numbers up, and divide by the number of numbers.

Arithmetic mean of a sample:

In this case the mean or average is:

Mean = 284 + 192 + 264 + 128 / 4 = 868 / 4 = 217

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
