A square has a side that is (x-3) units long. If the area of the square is 126.5625 sq units, what is the value of x?
Kitty [74]

Answer:

14.25 units

Step-by-step explanation:

Area of a square= l*b= (x-3)(x-3)=x^{2}-3x-3x+9=x^{2}-6x+9

x^{2}-6x+9=126.5625

x^{2}-6x-117.5625

Solving the equation using quadratic equation then as attached

x=14.25 units

To prove

x-3=14.25-3= 11.25 units

area=11.25*11.25=126.5625 sq units

The following graphs show the sampling distributions for two different point estimators, R and W, of the same population paramet
Sidana [21]

The graphs are illustrations of biased and unbiased distributions.

The true statement is (d) R is biased, and W is unbiased

<h3>How to determine which of the graph is biased</h3>

From the graph, we have the following highlight

  • The population parameter of graph R is at the right of the distribution
  • The population parameter of graph W is at the center of the distribution

The above means that:

Graph R is biased, and graph W is unbiased
