The correct answer is option B
(5 + 3i)(4+ 2i)
= 5(4+2i) + 3i(4+2i)
= 20 +10i + 12i +6i²
= 20 +22i +6(-1)
= 20 + 22i - 6
= 14 + 22i
Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 206 mg
Sample mean,
= 217.5 mg
Sample size, n = 14
Sample standard deviation, s = 14.9 mg
Claim:
The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.
Thus, we design the null and the alternate hypothesis
We use two-tailed t test to perform this hypothesis.

1 times 10 is 10. 10 times 10 is 100. So for those 3 models, the base is 10. All grids relate to the base 10 number system, because from left to right, the shaded part is getting bigger (increasing) by multiplying by 10. Hope this helps!
