Determine whether the piece of paper can be used to wrap the rectangular prism exactly once without any gaps or overlaps.
1 answer:
Answer:
No, because they do not have the same area.
Step-by-step explanation:
For the piece of paper to cover once without overlap or gaps, it must have the same area as the the total surface area of the prism.
The total surface area of the rectangular prism is:
The area of the rectangular sheet is:
Since the area of the piece of paper is more than the surface area of the rectangular prism there will be an overlap.

Step-by-step explanation:
Given that evolution theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and wakingdash–even if they are not exposed to the usual pattern of sunlight.
Sample size n = 8
df = 8- 1=7
Since population std deviation is not known, and sample size is small we can use only t test
(two tailed test at 5% level of significance)

sd 3.142857143
se 1.111167799
Test statistic = Mean diff/se = 1.595
p = 0.1546
since p >0.05, accept null hypothesis.
There is no evidence to prove that the steady cycle is different from 24 hours.
