Answer:
the two minus symbols cancel out making it positive 5
Step-by-step explanation:
First, we must calculate the weekly pay of an employee that is paid a fixed amount. Given that there are 52 weeks in a year, the weekly pay for a regularly paid employee is:
67,000 / 52 = $1,288.46
Now, we calculate the number of hours an employee that is paid hourly works per week:
0 + 10 + 8 + 8 + 7 + 6.5 + 4.5 = 44
So this employee is paid:
25 x 40 + 37.5 x 4 = $1,150
Therefore, it is recommended that a new employee goes for the salaried pay since the weekly earnings are greater in this option.

Answer:
256
Step-by-step explanation:
A calculator works well for this.

None of the minus signs are subject to the exponents (because they are not in parentheses, as (-1)^5, for example. Since there are an even number of them in the product, their product is +1 and they can be ignored.
1 to any power is still 1, so the factors (1^n) can be ignored.
After you ignore all of the things that can be ignored, your problem simplifies to ...
(2^2)(2^-3)^-2
The rules of exponents applicable to this are ...
(a^b)^c = a^(b·c)
(a^b)(a^c) = a^(b+c)
Then your product simplifies to ...
(2^2)(2^((-3)(-2)) = (2^2)(2^6)
= 2^(2+6)
= 2^8 = 256

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.
