Sketch the following region r. then express modifyingbelow integral from nothing to nothing integral from nothing to nothing with upper r f (r comma theta )da as an iterated integral over r. the region outside the circle requals1 and inside the rose r equals 2 sine 3 theta in the first quadrant.

f

step-by-step explanation:

f

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;

investment b is an ordinary annuity with $3,909.64 in the account after one year.
