I think this is false. p +/- z*sqrt (pq/n) . Notice that the formula has sqrt of n.
52.35 * 20% = 10.47
52.35+10.47 =62.82 total bill plus tip
62.82/ by number of people (this piece is missing)
Answer:
i think the answer is 41
Step-by-step explanation:
because 25 +15=40+1=41 that's why i think its 41
(ab)² and ab² are not equal. When you have something in parentheses being squared, you have to square everything inside, so in the case of (ab)², you have to "distribute" the ² to both variables inside. That gives you a²b², not just ab².
If the abstract way is kind of confusing for you, just pick two random numbers for a and b and plug them in to test it. Say a = 3 and b = 4. Then
(3*4)² = 3*4²
(12)² = 3*16
144 ≠ 48
