i = 15 sin(100πt + 0.6)
(b) The voltage V1 and V2 are represented by as follows,
V1 = 3sin(ωt)
V2 = 2 cos(ωt)
If V3 is the sum of V1 and V2,
Find the expression of V3 in sine waveform V3 = R sin(ω t + α )
and verify that the resultant voltage V3 is in the same frequency as V1 and V2.
Z = Z1Z2/Z1+Z2
If Z1 = 4 + j10 and Z2 = 12 – j3, calculate the impedance Z in both rectangular and polar forms.
Express the admittance in both rectangular and polar forms.
power = |V| × |I|× cos( φ)

Answer: T-tests T-tests are the most common statistical data analysis procedures used for testing hypothesis in statistics (Fagerland, 2012, pp.12-78). We have several types of t-tests, but the most commonly used t-test is the two sample t-test also called the student’s t-test. The two sample t-test normally tests whether two independent populations have some different mean values. In our case, we’ll compare the real mean weight o...Read More

Answers: Task 1 The given dataset contains information about 2000 households. A random sample of 200 households have been selected from the dataset using the technique of simple random sampling. Sampling has been done randomly as this is the most appropriate sampling technique that can be applied in this situation. There are certain advantages of this sampling technique for which this technique has been selected to be used for sampling. The...Read More
