<h3>
Answer: True</h3>
Explanation:
The area of the circle with radius 10 is...
A = pi*r^2
A = pi*10^2
A = 100pi
The surface area of the sphere with radius 5 is...
SA = 4pi*r^2
SA = 4pi*5^2
SA = 100pi
Both results are the same, so the claim is true. We can think of surface area as the amount of wrapping paper needed to cover the sphere.
I have no idea I’m answering this because I need to ask more questions
Answer:
The statistic for this case would be given by:
Step-by-step explanation:
Infromation provided
n=100 represent the random sample selected
X=18 represent the people who rates Pepsi as being "concerned with my health"
estimated proportion of people who rates Pepsi as being "concerned with my health"
is the value that reference to compare
z would represent the statistic
Hypothesis to test
For this case we can assume that the interest is check if the proportion of people who rates Pepsi as being "concerned with my health" is equal to 0.1 or not
, then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The satistic for this one sample proportion test is given by:
(1)
Replacing the info given we got:
Answer:Gabrielle is 2*Mikhail:
G = 2M We will use this value for G next
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
G+M = 45 Now in this equation substitute for G, like this:
2M+M = 45
3M = 45 Divide both sides by 3
M = 15 This is Mikhail, and the problem says that:
G = 2(15) = 30
Gabrielle is 30 and Mikhail is 15, and 15+30 = 45 just like the problem says
