Answer: Average change in sea lion's altitude per minute is 90.05 meters per minute.
Explanation:
Since we have given that
Height at which a sea lion dove from the water surface at sea level = (-)216.12 meters
We'll neglect the negative sign while finding the value of average rate of change.
Time taken to reach the above altitude = 2.4 minutes
So, Average change in the sea lions altitude per minute is given by
Hence, average change in sea lion's altitude per minute is 90.05 meters per minute.
<u>Answer:</u>
The correct answer option is D. 0.42.
<u>Step-by-step explanation:</u>
We are given the results of a survey in which people were asked if they prefer reading books or e-books.
We are to find the marginal frequency of the number of people who prefer to read books.
For that, we will divide the total number of people who prefer reading books by the total number of people surveyed.
Marginal frequency = 105/250 = 0.42
Answer:
The 99% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is
The the number that are parents x = 175
The proportion of parents is mathematically represented as
substituting values
The level of confidence is given as 99% which implies that the level of significance is
1%
The critical value for this level of significance is obtained from the table of critical value as
Generally the margin of error is mathematically evaluated as
substituting values
Generally the 99% confidence interval is mathematically represented as
substituting values
Answer:
1/2m - 4
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
we have
and the quadratic equation is
so we can see that
and the quadratic formula is
it should go this symbol ± instead of +-
so we insert each value
i don't know if you already know about imaginary numbers if you do then the answer is all the work
if you don't know, well just go until
and say there is no answer to this, because negatives don't have square roots
