Answer:
(29.14 ; 30.06)
Step-by-step explanation:
Given that'
Sample size (n) = 57
Mean (m) = 29.6
Population standard deviation (σ) = 2.7
Confidence interval = 80%
= (1 - 0.8) / 2 = 0.1
Mean ± z * σ/√n
Using the Z probability calculator : Z0. 1 = 1.28
Hence,
29.6 ± 1.28 * (2.7 / √57)
29.6 - (1.28 * 0.3576237) ; 29.6 + (1.28 * 0.3576237)
29.142241664 ; 30.057758336
(29.14 ; 30.06)

Answer:
The slope of the graph is 3/5
Step-by-step explanation:
We know that slope is nothing but rise over run. In this equation, the spacing is 3 points different vertically and 5 horizontally. If we do Rise Over Run, we will get 3/5 as our answer.
Answer:
14.4282 or 14.4 rounded
Step-by-step explanation:
(5 + 2i)(1 + 3i)
5 * 1 = 5
5 * 3 = 15i
2i * 1 = 2i
2i * 3i = 6i^2
So we have...
5 + 15i + 2i + 6i^2
5 + 17i + 6i^2
In order....
6i^2 + 17i + 5
