Answer:
20%
Step-by-step explanation:
Divide
14/70 = 0.20
Convert from a decimal to a percent. You can multiply by 100 or move the decimal two places right.
0.20 x 100 = 20%
Sample = 75 printers, Printers used by small businesses = 15
p(15) = 15/75 = 0.2
At 90% limit, Z =1.64
Limit of proportion of printers used by small business = p +/- Z Sqrt [p(1-p)/n]
=0.2 +/- 1.64 * Sqrt [0.2(1-0.2)/75] = 0.2 +/- 0.0757
Limit of proportion => (0.2-0.0757) to (0.2+0.0757) => 0.1243 to 0.2757 or 12.43% to 27.57%
18219 * (1 + 11.09%)^16 = ?
18219 * (1.1109)^16 = ?
? = 18224.380213
ANSWER = $18224.38
