Answer:
Step-by-step explanation:
In a study of the relationship between pet ownership and physical activity in older adults, 586 subjects reported that they owned a pet, while 1931 reported that they did not. Give a 98% confidence interval for the proportion of older adults in this population who are pet owners. Lower limit Incorrect: Your answer is incorrect. Upper limit
p ± z × (1 - p/n)
z = 98%
p = 586/1931
= 0.3034697048
n = 1931
Approximately = 0.3035
Confidence interval =
0.3035 + 2.326 × ( 1 - 0.3035/ 1931)
The construction is the construction of the Perpendicular bisector.
<h3>How to illustrate the information?</h3>
The steps for the construction of perpendicular bisectors are as follows:
Open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.
Call the two points where these two arcs meet X and Y. Draw the line between X and Y.
So, the point where this line meets the line segment; M is called the mid point and the line XY is the perpendicular bisector of the line AB.
The figure is a construction of perpendicular bisector.

Answer:
The answer is b. 35.5
Step-by-step explanation:
angle bisector always bisects an angle in to half amd in the question you have been told to tell the value of one half of the angle abc so the half of 71 would be 35.5
Step-by-step explanation:
Cost to make the film : $6500
Cost to set up production: $1500
Additional cost to make each video : $4
Additional cost to make n videos : $4n
total cost to make n videos = $6500 + $1500 + $4n = (8000 + 4n) dollars
overall cost to make each video
= total cost to make n videos ÷ n videos
= (8000 + 4n) / n
by definition, in order to "break even", the selling price for each video must be equal to the cost to make each video. i.e
Price, P(n) = (8000 + 4n) / n
Hence,
P(500) = [8000 + 4 (500)] / 500 = (8000 + 2000) / 500 = $20
This means that in order to break even selling 500 DVD's he has to sell each one for $20
