Answer:

y = -6/5x + 6/5

Step-by-step explanation:

equation formula is y = mx + b

m = slope

slope = change in y / change in x = (6 - -6) / (-4 - 6) = 12/-10 = -6/5

So m = -6/5

Now to find b, substitute one of the coordinates. Let's use (6, -6)

y = -6/5x + b

-6 = -6/5(6) + b

-6 = -36/5 + b

6/5 = b

So equation is y = -6/5x + 6/5

You can use the trig ratios. Draw a diagram to see which one is appropriate.
Tan would be used.
Tan29=x/20
20Tan29=x
Put this into your calculator and see what you get

The waiting time at an elevator is uniformly distributed between 30 and 200 seconds. what is the probability a rider must wait m

stira [4]

1.5 minutes = 90 second

The probability density function is

$f_X(x)=\begin{cases}\dfrac1{200-30}=\dfrac1{170}&\text{for }30\le x\le200\\\\0&\text{otherwise}\end{cases}$

so the probability of interest is

$\mathbb P(X>90)=\displaystyle\int_{90}^\infty f_X(x)\,\mathrm dx$
$\mathbb P(X>90)=\dfrac1{170}\displaystyle\int_{90}^{200}\mathrm dx$
$\mathbb P(X>90)=\dfrac{200-90}{170}=\dfrac{11}{17}\approx0.6471$
