Paisley and Damian are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Paisley is 315 miles away from the stadium and
Damian is 383 miles away from the stadium. Paisley is driving along the highway at a
speed of 42 miles per hour and Damian is driving at speed of 59 miles per hour. Let
P represent Paisley's distance, in miles, away from the stadium t hours after noon.
Let D represent Damian's distance, in miles, away from the stadium t hours after
noon. Write an equation for each situation, in terms oft, and determine whether
Paisley or Damian is closer to the stadium 5 hours after noon.

answer: was that a question or answer?

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;

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
