Answer:
And the best option for this case would be:
A. 0.050 to 0.112.
Step-by-step explanation:
Data given
represent the real population proportion of who support the cnadite for the northern half state
represent the estimated proportion of who support the candidate for the northern half state
is the sample size required the northern half state
represent the real population proportion of who support the candidate for the southern half state
represent the estimated proportion of people who support the candidate for the southern half state
is the sample size for the northern half state
represent the critical value
The confidence interval for the difference of two proportions would be given by this formula
For the 95% confidence interval the value of 
and 
, with that value we can find the quantile in the normal standard distribution and we got.
Replacing into the formula we got:
And the best option for this case would be:
A. 0.050 to 0.112.
Bobby is 7 and his sister is 3.
Explanation : his dads age : 41
since his dads age is six more than, you would subtract 6 from 41 to get 35.
and since 35 is 5 times bobby’s age you would divide 35 by 5 to get 7
So bobby is 7.
bobby’s sister :
bobby’s age : 7
bobby’s little sisters age is one less than half of his age you subtract 1 from 7 and you would get 6
Now that it’s one less you have to find half so divide 6 by 2 and you’ll get 3
So bobby’s sister is 3.
bobby’s age : 41 - 6 = 35
35 (divided by) 5 = 7
bobby’s sister : 7 - 1 = 6
6 (divided by) 2 = 3

➷The answer is True.
You can eyeball the triangle or also get a protractor and also see that this is a right triangle. Remember, right triangles have a right angle.

Answer:
C. 26
Step-by-step explanation:
Let’s suppose that the first question is worth ‘’x’’ amount of points. Then the second question will be worth x+4, the third question x+8, the fourth question x+12, the fifth x+ 16, the sixth x+20, the seventh x+24, the eighth x+ 28, the ninth x+ 32, and the last one x + 36.
The sum of the points of all these questions is equal to 10x + 180. Since the quiz has a total of 360 points, then
10x + 180 = 360.
Solving for x we get:
X = 18.
This means that the first question is worth 18 points, the second one 22 points (18 +4), the third one 26 points(18+4+4), and so on.
