Answer:

54.

Step-by-step explanation:

2|3xy-4|+x   when x = -2 and y = 4.

= 2|3*-2*4 - 4| + (-2)

= 2|-28| - 2

= 2*28 - 2     ( Note the vertical lines means the absolute value (positive 28)).

= 54.

A random sample of 200 voters in a town is selected, and 114 are found to support an annexa- tion suit. Find the 96% confidence
EastWind [94]

Answer:

a) 96% CI: 0.51\leq\pi\leq 0.63

b) If we estimate that the fraction of voters is 0.57, we can claim with 96% confidence that the error is equal or less than 0.06 from the estimated proportion.

Step-by-step explanation:

The proportion of the sample is

p=\frac{114}{200}=0.57

The standard deviation of the sample proportion is

\sigma=\sqrt{\frac{p(1-p)}{n} } =\sqrt{\frac{0.57(1-0.57)}{200} } =\sqrt{\frac{0.2451}{200} } =0.035

For a 96% CI, the z-value is z=1.751.

Then, the 96% CI can be written as:

p-z\cdot \sigma\leq\pi\leq p+z\cdot \sigma\\\\0.57-1.751*0.035\leq\pi\leq 0.57+1.751*0.035\\\\0.57-0.06\leq\pi\leq 0.57+0.06\\\\0.51\leq\pi\leq 0.63

b) If we estimate that the fraction of voters is 0.57, we can claim with 96% confidence that the error is equal or less than 0.06 from the estimated proportion.

Zahid is paid a set wage of $774.72 for a 36-hour week, plus time-and-a-half for overtime. In one particular week he worked 43 h
Llana [10]

Answer:

$1000.68

Step-by-step explanation:

\frac{774.72}{36}  = 21.52 \: (per \: hour) \\ \frac{21.52}{2}  = 10.76 \:  \\ 21.52 + 10.76 = 32.28(per \: hour \: of \: over \: time) \\  \\ 43 - 36 = 7(hours \: of \: overtime) \\  \\ 7 \times 32.28 = 225.96 \\ 774.72 + 225.96 = 1000.68
