Answer:
Maximum width of image that can be viewed clearly on the cylindrical screen is 10 ft
Step-by-step explanation:
Here we have
Circumference of screen = 2πr = 120 ft
Angle that can be viewed horizontally either side of focus = 15°
Total angle view = 30°
Size of image that can be viewed = Object within 30° of focus
Maximum width of image that can be viewed clearly = Perimeter of 30° arc section of cylinder
Maximum width of image that can be viewed clearly = 30/360×120 ft = 10 ft.
Maximum width of image that can be viewed clearly on the cylindrical screen = 10 ft.
Part A: 25+24h
25+24(3)=25+72=97
Try this solution:
1. Note, that 9*0.1=0.9; 0.9*0.1=0.09; 0.09*0.1=0.009, etc.
It means, the gives series is geometric sequence, where a₁=9, q=0.1.
2. Using a₁=9 and q=0,1 it is possible to calculate the sum of this sequence:
answer: 10
Given claim: A coin favors heads when tossed, and there are
90 heads in 100 tosses.
Answer: There isn’t sufficient evidence to support this
claim, because the coin is a fair coin.
Given claim: Movie patrons have IQ scores with a standard
deviation that is less than the standard deviation of 15 for the general
population. A simple random sample of 40 movie patrons result in IQ scores with
a standard deviation of 14.8.
Answer: Claim is either true or false
