Suppose you have 54 feet of fencing to enclose a rectangular dog pen. The function a=27x-x^2, where x=width, gives you the area

andrew-mc [135]

For maximum area, we take first derivative and then equalize it to zero
A(x) = 27x- x^2 
A'(x) = 27 - 2x 

Set that equal to zero and solve for x : 
27 - 2x = 0 
27 = 2x ......................... [ added 2x to both sides ] 
13.5 = x ........................ [ divided both sides by 2 ] 

So the area will be
A = 27(13.5) - (13.5)^2 
 = 364.5 - 182.25 
 = 182.3 ft^2

On each trial of an experiment, a participant is presented with a constant soft noise, which is interrupted at some unpredictabl

Andre45 [30]

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
