Answer:
The correct answer is:
(a) 0.54
(b) 0.0385
Step-by-step explanation:
Given:
Restaurant tax,
p = 0.54
Sample size,
n = 168
Now,
(a)
The mean will be:
⇒ μ 

(b)
The standard error will be:
= ![\sqrt{[\frac{p(1-p)}{n} ]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%5D%7D)
= ![\sqrt{[\frac{(0.54\times 0.46)}{168} ]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%5Cfrac%7B%280.54%5Ctimes%200.46%29%7D%7B168%7D%20%5D%7D)
= ![\sqrt{[\frac{(0.2484)}{168} ]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%5Cfrac%7B%280.2484%29%7D%7B168%7D%20%5D%7D)
= 
Negative 73
drop of 73
minus 73
below 73
taking away 73
Answer:
270
Step-by-step explanation:
use lising method start with the larger number
54:54,108,162 216,270
15: instead of listing all 18 multiples, divide 15 into the multiples of 54 it only goes evenly into 270.
Or divide both denominators into your fir answer and see the smallest bith can go into evenly.
Answer:
x and (x - 6)
Step-by-step explanation:
y = a(x - h)² + k
h = 3 k = -2
y = a (x - 3)² -2
For point (0 , 0) on the function
0 = a (0 - 3)² -2
0 = 9a - 2
a = 2/9
a (x - 3)² -2 = 2/9 (x² - 6x + 9) - 2 = 2/9 * x * (x - 6) + 2 - 2 = 2/9 * x * (x-6)
