First you have to get the equation into slope/intercept format: y = mx + b

3y > -3+6x\\\\\frac{3y}{3} >\frac{-3+6x}{3} \\y >\frac{3(-1+2x)}{3} \\y > -1+2x\\\\y>2x-1

So the slope m = 2, and the y-intercept b = -1.

b tells you where the line intersects the y axis. The slope is rise (vertical distance) over run (horizontal distance). I have attached my best attempt at drawing this without graph paper.  The dotted line represents the inequality, and the solution set includes the values above the line which is why it is shaded. Hope this helps!

Answer:

Step-by-step explanation:

Confidence interval for the difference in the two proportions is written as

Difference in sample proportions ± margin of error

Sample proportion, p= x/n

Where x = number of success

n = number of samples

For the men,

x = 318

n1 = 520

p1 = 318/520 = 0.61

For the women

x = 379

n2 = 460

p2 = 379/460 = 0.82

Margin of error = z√[p1(1 - p1)/n1 + p2(1 - p2)/n2]

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.025 = 0.975

The z score corresponding to the area on the z table is 1.96. Thus, confidence level of 95% is 1.96

Margin of error = 1.96 × √[0.61(1 - 0.61)/520 + 0.82(1 - 0.82)/460]

= 1.96 × √0.0004575 + 0.00032086957)

= 0.055

Confidence interval = 0.61 - 0.82 ± 0.055

= - 0.21 ± 0.055

- 1/3 - (-1/2) what’s the answer? Someone please help!
Natasha_Volkova [10]

Answer:

1/6

Step-by-step explanation:

So we are subtracting a negative which is the same as adding.  Our equation becomes -1/3+1/2.  To add fractions we need a common denominator (the denominator of a fraction is the number on the bottom)  To fine the least common denominator we need to find the lowest number that both 3 and 2 go into which is 6.  Then we will multiply each fraction by the number that will give us 6 for a denominator which is 2 for -1/3 and 3 for 1/2.  So -1/3 times 2 is -2/6 and 1/2 times 3 is 3/6.  Our equation is now -2/6+3/6.  Now we will add the numerators ( the numerator is the number on the top of the fraction) and the denominators stay the same when adding or subtraction fractions -2/6+3/6=1/6

I hope this helps and please let me know if there is anything you are confused about or is still unclear, I will be happy to help!
