Answer:
Step-by-step explanation:
Let p be the population proportion of readers who would like more coverage of local news.
As per given , we have
sample size :=1600
sample proportion :
The confidence interval for population proportion is given by :-
From z-table ,
For 99% confidence interval the z-value is 2.576.
Substitute all the values in the above formula , we get
The 99% confidence interval for the proportion of readers who would like more coverage of local news as
Hence, the 99% confidence interval for the proportion of readers who would like more coverage of local news is .
For the first the correct answer is C
the second
the perimiter of the triangle is equal the sum of the sides
x +x-1+x-2= 12
3x = 12 +3
x= 15/3 = 5
First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.
So we will get
Now we use sine law, which is
Substituting the values, we will get
The formula of area of triangle, for the given triangle is
It is y=3/5x + 3
This is because the slope is 3/5 and the y intercept is 3.
6.42 pm is the answer. You can think backward 8 hours before 2:12 am, which is 6:12pm. Now, go 'forward' a half an hour, to 6:42pm. Answer: 6:42pm.
