The slope formula is y=mx+b
m = slope
when you rearrange the equation into the slope formula you have to find a number that divides into -2/3 to equal 6. Since negative divided by a negative equals positive, it should be either -4 or -1/9. When you -2/3 ÷ -1/9 = 6.

The correct answer is -1/9

For this problem what I did was that I multiplied 100 x 34 = 3,400 and subtracted that answer with 5,086. The answer I got was 1
inessss [21]

Answer:

The answer rounded to the nearest whole number is 1729

Step-by-step explanation:

Set it up like this:  Percent in fraction form = x over total

So:  34/100  = x/5086

You then multiply:   34 x 5086 = 172924

Then divided that number by 100:   172924 divided by 100 = 1729.24

Then round the number to the nearest whole number:   1729

Hope this helps good luck!

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,
REY [17]

Answer:

a) 217

b) 1351

c) 5403

Step-by-step explanation:

Given that:

confidence interval (c) = 0.95

\alpha =1-0.95=0.05\\\frac{\alpha }{2} =\frac{0.05}{2}=0.025

The Z score of \frac{\alpha }{2} is from the z table is given as:

Z_{\frac{\alpha }{2} }=Z_{0.025}=1.96

Range = $45000 - $30000 = $15000

The standard deviation (σ) is given as:

\sigma=\frac{Range}{4} =\frac{15000}{4}=3750

Sample size (n) is given as:

 n=(\frac{Z_{\frac{\alpha}{2} }\sigma}{E} )^2

a) E = $500

n=(\frac{Z_{\frac{\alpha}{2} }\sigma}{E} )^2= (\frac{1.96*3750}{500} )^2 ≈ 217

b) n=(\frac{Z_{\frac{\alpha}{2} }\sigma}{E} )^2= (\frac{1.96*3750}{200} )^2 ≈ 1351

c) n=(\frac{Z_{\frac{\alpha}{2} }\sigma}{E} )^2= (\frac{1.96*3750}{100} )^2 ≈ 5403
