Answer:
2080 IU
Explanation:
Given
Ratio of vitamin A in cow milk to goat milk = 3 : 4
Required
Determine the content of vitamin A in goat milk if cow milk has 1560 IU
The given parameters shows a direct proportion.
Let G represents Goat and C represent Cow
Given that there exists a direct proportion;
C = K * G where K represents the constant of proportionality.
Solving for K when C = 3 and G = 4
C = K * G becomes
3 = K * 4
3 = 4K
Divide through by 4
¾ = K
K = ¾
Now, solving for G given that C = 1560IU;
We'll make use of the same formula as above
C = K * G
Substitute 1560 for C and ¾ for K; the expression becomes
1560 = ¾ * G
Multiply both sides by 4
4 * 1560 = 4 * ¾ * G
6240 = 3 * G
Multiply both sides by ⅓
⅓ * 6240 = ⅓ * 3 * G
2080 = G
G = 2080
Hence, the vitamin A in the goat milk is 2080IU

All the sampling methods used in the given survey are; convenience, systematic, and voluntary sampling.
<h3>What is the sampling method used?</h3>
From the question, we see that the surveyor selects the twentieth student who enters the building.
Now, the student do not enter the building to be surveyed but instead for other reasons and as such the researcher takes advantage of that and selects them. This is a form of convenience sampling.
It is also a form of systematic sampling because the researcher selects every twentieth student and not any other.
Lastly, it is a form of Voluntary sampling because the students selected to participate in the survey are free to choose whether to participate in the survey or not.
