At a local college, of the male students are smokers and are non-smokers. Of the female students, are smokers and are non-smoker
Alla [95]

Answer:

The fraction of males who are smokers = 10/500 = 1/50

The fraction of females who are smokers = 40/403

The probability that both are smokers is the product of these two:

P(both) = (1/50)*(40/403) = (4/5)*(1/403)

Write the equation of a line that passes through the points ( 2 , - 5 ) and ( 8 , - 2 )
kati45 [8]

Answer:

y=\frac{1}{2}x-6

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Determine the slope (m)</u>

m=\frac{y_2-y_1}{x_2-x_1} where two points that fall on the line are (x_1,y_1) and (x_2,y_2)

Plug in the given points (2,-5) and (8,-2)

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{-2-(-5)}{8-2}\\=\frac{-2+5}{8-2}\\=\frac{3}{6}\\=\frac{1}{2}

Therefore, the slope of the line is \frac{1}{2}. Plug this into y=mx+b:

y=\frac{1}{2}x+b

<u>2) Determine the y-intercept (b)</u>

y=\frac{1}{2}x+b

Plug in one of the given points and solve for b

-5=\frac{1}{2}(2)+b\\-5=1+b

Subtract 1 from both sides to isolate b

-5-1=1+b-1\\-6=b

Therefore, the y-intercept of the line is -6. Plug this back into y=\frac{1}{2}x+b:

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

I hope this helps!
