thats the answer i did it too
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

(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
=
chi square = 7.81
Hence option d is right.
The equation described above can also be written as,
y = -x² + 100x + 4000
To get the number of notebooks that will give them the maximum profit, we derive the equation and equate to zero.
dy/dx = -2x + 100 = 0
The value of x from the equation is 50. Then, we substitute 50 to the original equation to get the profit.
y = -(50^2) + 100(50) + 4000 = 6500
Thus, the maximum profit that the company makes is $6,500/day.
Answer:
Least to greatest is: 0.0625, 6.75% and
.
Step-by-step explanation:
Given:
The three quantities to compare are:
6.75%, 0.0625, and 
Let us convert each into percentage.
6.75% is already in percentage.
We multiply a number by 100 to convert it to percentage form.
So, 

Now, on comparing all the three percentage, we conclude that,
70% is the greatest and 6.25% is the least.
So, order from least to greatest is:
