Answer:

- the angle at H is 120 degrees

- the missing segment is DC

Step-by-step explanation:

The "roof" FGH is bigger than 90 degrees because FG and GH are not acute. .

Without instruction we can assume FGH is 120 degree.

This means GHF is 30 degrees to complete the triangle FGH.

So the angle around H, or JHG is 90 + 30 = 120 degrees

For the ratio, we can simply look at the comparison between the small figure   DJHGF

and the large figure DCBAE, and we see that the denominator

DJ in the small figure is DC in the large figure.

Answer:

Option d

Step-by-step explanation:

Given that television networks frequently run public opinion polls on issues of concern. One network conducted a scientific poll asking a question concerning the approval rating of the way President Obama was handling the Iraq War. At about the same time a second network ran an online poll using a very similar question.

Observed data is

Poll              Scien      Online total

   

approve    339   385      724

disapprove 780        573     1363

                 1119        958     2087

H_0: Both scientific and online are consistent\\H_a: not consistent

(Two tailed chi square test)

Let us find out expected and chi square

Expected = row total x column total/grand total

The cell count expected in the online poll for those who approve

=\frac{724*968}{2087} \\=333.94

chi square = 7.81

Hence option d is right.

Mariulka [41]

Answer:

98

Step-by-step explanation:

ABSOLUTE BRACKETS MEAN ABSOLUTE VALUE- this means that negatives will come out as positives since their absolute values are the same. So |-9| is just 9.

|-81-17| (apply the rule I just gave you)

|81+17|

98
