The answer to the problem is x=8
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.
Answer:
n = 0
Step-by-step explanation:
slope = y2-y1/x2-x1
so
-5 -n / 4-3 = -5
-5 -n /1 =-5
-5 - n = -5
n = 0
Answer:
x= 70 degrees
y= 30 degrees
z= 20 degrees
Step-by-step explanation:
Angle x will be supplementary to the 110 degree angle adjacent to it since it will form a straight line. 180 - 110 = 70 degrees.
Since we know the other two angle measures in the triangle that angle y is in, we can do 180 - (110 + 40) to find angle y. 180 - 150 = 30 degrees
We also know the other 2 angle measures of the triangle that angle z is in. We can find angle z by doing 180 - (70 + 90). 180 - 160 = 20
Answer:
165.
Step-by-step explanation:
The nth term is an = a1 + (n - 1)d.
The common difference (d) is 7 and the first term (a1) is -3, so the 25th term
= a25 = -3 + (25-1)*7
= =3 + 24*7
= 165.
