In the figure, we are given with the shaded area and we are to determine the area of the shaded figure. The equation that would allow us to answer this is,
                  Area = Length x width

As it can be seen in the figure, the length of the shaded area is 30'. From the front view of the figure, it can be deduced that the width is the hypotenuse of the right triangle. Through the Pythagorean theorem,
                      x² + x² = w²
Substituting the known values of x,
                  (20')² + (20')² = w²
The value of w is equal to 20√2 or 28.28 units

From the equation above,
        Area = (30')(28.28')
         <em>Area = 848.53 ft²</em>

Thus, the answer to this item is letter C. 850.

An ornithologist has 4 bird feeders at separate locations. She wonders if birds are equally likely to visit each of the feeders.
Marianna [84]

Answer:

the x² test statistic 13.71

Option a) 13.71 is the correct answer.

Step-by-step explanation:

Given the data in the question;

Feeder                     1      2      3       4

Observed visits; o_i  60   90   92    58

data sample = 300

Expected e_i = 300 / 4 = 75

the x² test statistic = ?

X^2_{stat = ∑[ (o_i - e_i)²/e_i]

X^2_{stat = [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]

X^2_{stat = [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]

X^2_{stat = 13.7066 ≈ 13.71

Therefore, the x² test statistic 13.71

Option a) 13.71 is the correct answer.

Hello!

You have to find what the rule is

12/24 = 0.5
6/12 = 0.5
 -6/-12= 0.5

They multiply x by 0.5

the rule is multiply x by 0.5 or y = 0.5x

Hope this helps!
