Shannon is traveling from New York City to Washington, D. C. She wants to go by train so she can see the views. Since she will be driving home with a family member, she only priced the cost of a one-way ticket on Amtrak for any time of day on February 15. Below is an ordered listing of all fares that were available for selection on that day. Find the percentile rank for a fare of $119. fill in the blank 1 Find the percentile rank for a fare of $272. fill in the blank 2

Based on your first two answers, which train fare would have a percentile rank of approximately 82%?

f(x)= 4x + 1 is written in function notation and is read “f of x equals 4x plus 1. ... B) 3x = y – 2 and f(x) = 3x – 2 ... Given f(x) = 3x2 + 2x + 1, find f(0), f(2), and f(−1).

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
