The line is stretched from M to P
The point O is in between M and P, so the length OM add length OP will give the full length of MP
OM =
OP =
The length MP = OM + OP =
If N is the midpoint of MP, then the length MN is half of the length MP
MN =
Answer:
160.
Step-by-step explanation:
The area of the base is 64 since each side is 8, 8x8 is equal to 64. Then you have the lateral faces with a length of 8, and a height of 6, which is 48, but since they are triangles, you divide by 2, finally add 24+24+24+24+64 and your final answer is 160.
Answer:
x = 9
Step-by-step explanation:
Using the z-distribution, it is found that the 95% confidence interval for the proportion of all U.S. adults who play video games is (0.4681, 0.5119). It means that we are 95% sure that the true proportion of all U.S. adults who play video games is between 0.4681 and 0.5119.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have that:
- 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so 
.
- 49% out of 2001 U.S. adults play video games, hence
.
The lower bound of the interval is:
The upper bound of the interval is:
The 95% confidence interval for the proportion of all U.S. adults who play video games is (0.4681, 0.5119). It means that we are 95% sure that the true proportion of all U.S. adults who play video games is between 0.4681 and 0.5119.
