You gave the answer right in your question
Answer:
d
Step-by-step explanation:
If x represents the slant height, the graph would be a straight line.
If x represents the radius, the graph would be a parabola.
Looking at the answers, we're looking for x to be the slant height, so we're looking for a straight line.
We are looking for g(x). Answers a and b are wrong.
In g(x) r is fixed to 5 (this is given). So the slant height in the smallest possible cone would still be at least 5.
So the domain is x > 5.
d is your answer.
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)
