In Seychelles warblers, young adult females known as subordinates sometimes hang around the territories of older birds. Sometimes these subordinates help feed the offspring of the older birds, and sometimes not. In one study, subordinate birds that did not help were genetically assessed to discover whether they were related to the offspring of the older birds (Richardson et al. 2003). A "relatedness" score was assigned to each subordinate, with a value of zero meaning no relationship to the offspring. Out of five subordinates examined, the mean relatedness was −0.05−0.05 with standard deviation 0.450.45 (relatedness can be negative if by chance sampled individuals are less related than the population as a whole). What is the 95%95% confidence interval for relatedness of unhelpful subordinates to the offspring?

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
