A study of 420,095 cell phone users resulted in 135 who developed cancer of the brain or nervous system. When comparing this sample group to another group of people who did not use cell phones, it was found that there is a probability of 0.512 of getting such sample results by chance. What do you conclude?
Answers
Answer:
Results of the original study are inconclusive
Step-by-step explanation:
A probability of 0.512 that the results obtained in the controlled sample could be obtained by chance, means that it is more likely than not ( P>0.50) to get this results by chance. What this means is that the results of the original study linking brain cancer development to cell phone use are inconclusive.

What is exponential decay?
A quantity is subject to exponential decay if it decreases at a rate proportional to its current value.
Given that, You purchase a car in 2010 for $25,000. The value of the car decreases by 14% annually.
The exponential decay is given by =
A = final amount
P = principal amount
r = rate of decrease.
t = 10
Therefore,
A = 25000(1-0.14)¹⁰
A = 25000×0.86¹⁰
A = 5532.53
Hence, the value of the car in 2020 is $5532.53

Step-by-step explanation:
box 1 (left one): 10*9*9=810
box 2 (right one): 18*4*10=720
720+810=1,530
Answer:
1530 cm^3
Step-by-step explanation:
They are two Rectangular Prism.
prism 1.
length l = 18 cm
width w = 10 cm
height h = 4 cm
diagonal d = 20.976177 cm
total surface area S_tot = 584 cm^2
lateral surface area S_lat = 224 cm^2
top surface area St_op = 180 cm2
bottom surface area S_bot = 180 cm^2
volume V = 720 cm^3
Prism 2.
length l = 10 cm
width w = 9 cm
height h = 9 cm
diagonal d = 16.1864141 cm
total surface area S_tot = 522 cm^2
lateral surface area S_lat = 342 cm^2
top surface area Stop = 90 cm^2
bottom surface area Sbot = 90 cm^2
volume V = 810 cm^3
Add 720 cm^3+810 cm^3 = 1530 cm^3
Agenda: l = length
w = width
h = height
d = diagonal
S_tot = total surface area
S_lat = lateral surface area
S_top = top surface area
S_bot = bottom surface area
V = volume
Formula: Volume of Rectangular Prism: V = lwh
