Find the equation of the linear function 'g' going through (20,5) and (-5,-8). Use 'u' for your input variable.

frosja888 [35]

Answer:

See below

Step-by-step explanation:

<u>Use the slope-intercept form, which will be in this case:</u>

g(u) = mu + b, where m is the slope, b is the y- intercept

<u>Find the slope:</u>

$m=(y_2-y_1)/(x_2-x_1)$
$m=(-8-5)/(-5-20)=(-13)/(-25)=13/25$

<u>Find the value of the y-intercept:</u>

$5=1/25*20+b$
$b=5-4/5=21/5$

<u>The equation is:</u>

$g(u)=\frac{13}{25} u+\frac{21}{5}$

Answer:

23.44%

Step-by-step explanation:

The probability of getting a 4 on the first 2 throws and different numbers on the last 5 throws = 1/6 * 1/6 * (5/6)^5

= 0.01116

There are 7C2 ways of the 2 4's being in different positions

= 7*6 / 2 = 21 ways.

So the required probability = 0.01116 * 21

= 0.2344 or 23.44%.
