Answer:
a. 8,953.5 seconds
b. 14,400 seconds (check note)
Step-by-step explanation:
a.
y=-4x
y=-35814 (negative because this is underwater)
-35814=-4x
8953.5
The model suggests it would take 8,953.5 seconds for DeepSea Challenger to reach the bottom (2.487083333 hours, or about 2 hours and 30 minutes).
b.
y=4x
x=3600 (positive because the vessel is rising)
4(3600)
14400
It took 14,400 seconds for the DeepSea Challenger to ascend to the surface.
[also note: I'm not sure if the second question is asking for how many seconds it takes to ascend to the surface with reference to the 4 seconds in the previous question (which is how I answered part b) or if it's asking how many seconds 1 hour is, and in that case. the answer is 3,600 seconds. I hope this helps and sorry if it's unclear!]
Answer: 
Step-by-step explanation:
The confidence interval for population proportion is given by :-
Given : Sample size : 
The proportion of people selected consumers who had opportunities to send in a rebate claim form after purchasing a product said they never did so =
Significance level : 
Critical value : 
Now, the 95% confidence Interval for the true proportion of such consumers who never apply for a rebate will be :-
Hence, a confidence Interval for the true proportion of such consumers who never apply for a rebate .
Answer:
20 mangos
Step-by-step explanation:
1. Divide $600 by 12. Your answer should be $50. This means that every mango costs $50.
2. You now need to solve the expression: 1000 ÷ 50 which equals 20. This means that with $1000 Jane can buy 20 mangos.
