Answer:

y = (x - 4)² - 19

Step-by-step explanation:

Standard form of quadratic function:

y = ax² + bx + c

Vertex form:

y = (x - h)² + k

Convert the given function by completing a square:

y = x² - 8x - 3 =

x² - 2*4*x + 4² - 4² - 3 =

(x - 4)² - 19

Answer:

1.d. None of these measures (do not exist interpreted as all of these exist)

2.The mean is increased from 346.8 to 361.32

Step-by-step explanation:

After calculations we find that all the measures of central tendency exist for this data. The mean , median and mode can be easily calculated .

The mean is 346.8

The mode is 281

The median is 316

Suppose that the measurement 806 (the largest measurement in the data set) were replaced by 1169. The mean would be affected by the change.

The mean is 361.32

The mode is 281

The median is 316

The mean is increased from 346.8 to 361.32
