So it's 8√2 cause you do c=a/h and manipulate the formula for 8/cos45 :)
Answer:
A) When using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. True.
The Shell method is a technique used to find the volume of a solid of revolution. Here, we take thin shells with axis coinciding with the axis about which the region whose volume is to be found, is revolved.
B) If a region is revolved about the y-axis, then the shell method must be used. False.
This method can be used with any axis of rotation.
C) If a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y. True.
The washer method uses thin disks with infinite width but the shell method uses thin concentric shells with infinite width about the axis of revolution. So, the statement is true.
Answer:
145$ is the markup price i think
Step-by-step explanation:
100$+ 45%=x
100/100%=1
45%*1=45
100$+45$= 145$
We can make a conclusion about the data collection method used was fair since both shoe designs were tested on identical parameters option (B) is correct.
<h3>What is simple random sampling?</h3>
Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.
We have:
Two manufacturers of the shoe company:
SportsPlus came up with a design that it claims performs even better than Fastex's design.
SportsPlus decided to test the claims:
- It created two groups of 15 randomly selected athletes each.
- Members of both groups were pretested and determined to have equal athletic ability.
- Additionally, they followed the same nutrition plan and training program during the study.
Based on the data the statement "The data collection method used was fair since both shoe designs were tested on identical parameters".
Thus, we can make a conclusion about the data collection method used was fair since both shoe designs were tested on identical parameters option (B) is correct.
