Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is
The mean is
The standard deviation is
Generally the standard error of this measurement is mathematically represented as
substituting values
ppb
Now the probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb represented as P(X < 15 )
Next is to find the z value
Now checking the z-table for the z-score of -1 we have
Comparing the functions, it is found that:
- The function Kimora's travel based on Jim's travel is of: D. g(x) = f(x) + 80.
- Lonnie's function based on Kimora is: B. h(x) = g(x - 2).
-----------------------------------------
Jim's equation is of:
Kimora's equation is of:
The -55x term is common to both functions, while the constant on g is 80 more than f, thus:
Which means that the answer to the first question is given by option D.
Lonnie started traveling two hours before Kimora's, using the same equation of motion, just with the input x reduced by 2, thus:
Which means that the answer to the second question is given by option B.
