Answer:
i think the area is 21 srry if im wrong
Step-by-step explanation:
In the case above, the correct vectors are:
- <25.98, -15>.
- <1.71, 4.7>.
<h3>What is the ship vector about?</h3>
The solution for the Ship's vector are:
Note that the Horizontal aspect = 30 cos 30
= 25.98.
For the Vertical aspect = 30 sin(-30)
= -15.
Hence it will be <25.98, -15>.
In regards to the current's vector:
The Horizontal aspect= 5 sin 20
= 1.71.
The Vertical aspect = 5 cos 20
= 4.7.
Hence it will be <1.71, 4.7>.
Therefore, In the case above, the correct vectors are:
- <25.98, -15>.
- <1.71, 4.7>.

1) This is a Two tailed Test.
2) Decision rule is; If the p-value is greater than 4% fail to reject H₀.
3) P-value = 0.00968764 and so we reject H₀
<h3>How to state the decision rule in hypothesis testing?</h3>
We are given the hypothesis as;
Null Hypothesis; H₀: m₁ = m₂
Alternative Hypothesis; H₁: m₁ ≠ m₂
1) Since the alternative hypothesis has "not equal to sign", then it is a two tailed test.
2) Since we are told to use significance level as 0.04, then we can say that the decision rule is;
If the p-value is greater than 4% fail to reject H₀.
3) Using a 2-Sample Z-Test online TI calculator gives the test statistic as;
z = 2.5868
4) From z-score calculator, p-value equals 0.00968764. This is less than 0.04 and as such the decision regarding H₀ is to reject H₀.
5) P-value = 0.00968764
