A penny is worth 1 cents. So, 84 pennies is 84 cents or $0.84
A dime is worth 10 cents, So, 300 dimes is 30 dollars or $30 dollars

84 pennies and 300 dimes is equivalent to 30 dollars and 84 cents.
Answer:
(b) 4,445
Step-by-step explanation:
If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?
Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)
So n=(Z/E)^2*p*(1-p)
=(1.96/0.015)^2*0.5*0.5
=4268.444
Take n=4269
