Answer:
![44cm^{2}](https://tex.z-dn.net/?f=44cm%5E%7B2%7D%20)
Step-by-step explanation:
![v = \frac{1}{3}bh](https://tex.z-dn.net/?f=v%20%3D%20%20%5Cfrac%7B1%7D%7B3%7Dbh)
V=1/3BH
where B= area of base
B=
![\frac{4 \times 11}{2} = 22cm^{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%20%5Ctimes%2011%7D%7B2%7D%20%20%3D%2022cm%5E%7B2%7D%20)
H= height
B×H
![\frac{22 \times 6}{3} = 44cm^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B22%20%5Ctimes%206%7D%7B3%7D%20%20%3D%2044cm%5E%7B3%7D%20)
Answer:
your answer will be ![y=cos\frac{1}{2} x](https://tex.z-dn.net/?f=y%3Dcos%5Cfrac%7B1%7D%7B2%7D%20x)
Step-by-step explanation:
hope it helps !
3x-x = 21+15
2x=36
36/2=18
x=18
Using the Central Limit Theorem, it is found that the condition that applies to this test is:
C. The sample includes at least 30 employees from each department.
<h3>What does the Central Limit Theorem state?</h3>
It states that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
From this, since we have a skewed variable, it is found that a sample size of at least 30 is needed, hence option C is correct.
