Answer:
The limits are 0.6472 and 0.7528
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
Of the 500 surveyed, 350 said they would vote for the Democratic incumbent.
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The limits are 0.6472 and 0.7528
Answer:
D
Step-by-step explanation:
When the equation equals itself on both sides, you have an infinite solutions.
So we just go through each of the choices.
So D works because it has 0=0
A is the answer. Hope this helps
The sum of opposite pair of a quadrilateral is 180°
so ∠DAB +∠DCB=180
We are given ∠DCB=122°
122° +∠DAB =180°
∠DAB =180°-122°= 58°
Answer : ∠DAB =58°
