Two exterior angles of a triangle equal 100° and 150°. Find all the interior angles
harkovskaia [24]
180°-100°= 80° (angle 1)
180°-150°= 30° (angle 2)

180°-80°-30°= angle 3
angle 3 = 70°

∴ the interior angles are 80°, 30° and 70°

What is the value of n when 6n-14=3n+7
Goshia [24]

answer: n=7

work:

6n-14=3n+7

6n-14 (+14) = 3n+7 (+14)   add 14 to both sides

6n=3n+21

6n(-3n)=3n(-3n)+21    subtract 3 from both sides

3n=21

3n/3= 21/3    divide by 3 on both sides

n=7

You give tours on the Great Lakes and talk about points of interest. A lighthouse typically has 2 beacons that rotate together—b
tatiyna

Since the beacons rotate together, the angular speed is constant.

From the time you see the first beacon, you have to wait for the lighthouse to make 120°, i.e. 1/3 of a whole turn.

So, if T is the time it takes for the lighthouse to make a whole turn, the interval between the first and the second beacon is T/3.

The interval between the second and third beacon is the amount of time it takes to the lighthouse to make the remaining 2/3 of a turn, so that you'll see the first beacon again. So, this time is 2T/3

So, the ratio is

\dfrac{2T}{3}\div\dfrac{T}{3}=\dfrac{2T}{3}\cdot\dfrac{3}{T}=2

So, the time between the second and third beacon is twice as much the time between the first two.

Let X and Y be random variables with the following joint moment generating function: M_{X,Y}(s,t)=0.1+0.2e^s+0.3e^t+0.4e^{s+t}
MA_775_DIABLO [31]

We obtain the joint PMF directly from the joint MGF:

M_{X,Y}(s,t)=0.1+0.2e^s+0.3e^t+0.4e^{s+t}

\implies\mathrm{Pr}[X=x,Y=y]=\begin{cases}0.1&\text{for }x=y=0\\0.2&\text{for }x=1,y=0\\0.3&\text{for }x=0,y=1\\0.4&\text{for }x=y=1\\0&\text{otherwise}\end{cases}

Then

\mathrm{Pr}[X=Y]=\mathrm{Pr}[X=Y=0]+\mathrm{Pr}[X=Y=1]=0.1+0.4=\boxed{0.5}
