Sample size: n= 2322
Sample proportion 
Critical z-value for 90% confidence level : z*=1.645
The confidence interval for population proportion:
A 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years:
Hence,
6 pencil cases would cost $5.94.
You can create an expression to represent the scenario.
6×$0.99
=$5.94 for 6 pencil cases
Answer:it would be 2:22

Answer:
A. 2086 yd²
Step-by-step explanation:
SA = 2lw + 2wh + 2lh
SA = 2*17*20 + 2*20*19 + 2*17*19
SA = 680 + 760 + 646
SA = 2086
Hope this helps :)
Answer:
Dividend
Divisor
The rule of division of polynomial which is same as division of real numbers states that
Dividend = Divisor × Quotient + Remainder
The division process is shown below.
Quotient = x+5
Remainder =0
