210 - ( 30 * x )
**I assume the question asks for total minutes.
The area would be 132cm^2 (squared)
(9x4)x2+(7+8)x4 =132
The perimeter you just add everything up so it’s 65cm
15+13+4+7+9+4+13

Answer:
Step-by-step explanation:
Given that 33.4% of people have sleepwalked.
Sample size n =1459
Sample favourable persons = 526
Sample proportion p = 
Sample proportion p is normal for large samples with mean = 0.334 and
std error = 
a) P(526 or more of the 1459 adults have sleepwalked.)

b) Yes, because hardly 1.4% is the probability
c) 33.4 is very less compared to the average. Either sample should be improved representing the population or population mean should be increased accordingly.
