Answer:

11/12

Step-by-step explanation:

Find the common denominator.

4 and 3 both go into 12.

4 goes into twelve three times so multiply the denom and the num.

9/4 = 27/12

3 goes into twelve four times.

4/3 = 16/12

Subtract.

27/12-16/12

= 11/12

Fill in the other coordinate for the line 2x - 5y = 11: (4, )
enot [183]
2x - 5y = 11.              (4, a).  x = 4, y = a

Substituting into 2x - 5y = 11

2(4) - 5(a) = 11

8 - 5a = 11

-5a = 11 - 8

-5a = 3

a = 3/-5 = -3/5 =- 0.6

Other coordinate =  -3/5 = -0.6

Anuta_ua [19.1K]

Answer:

175

Step-by-step explanation:

The sample size n in<em> Simple Random Sampling</em> is given by

\bf n=\frac{z^2s^2}{e^2}

<em> where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation. </em>

Replacing values

\bf n=\frac{(1.96)^2(675)^2}{(100)^2}=175

So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000
