What is the probability of rolling a product of 30 when rolling two dice?
Nimfa-mama [501]
It has a probability of 2 out of 36 chances as there are only two ways it can happen out of 36 different combinations that can be rolled. Product means multipication also in Maths 

<span>The first probability on the first roll is that Dice 1 must be a 5 and Dice 2 must be a 6 so that 5x6=30 </span>

<span>The second probability on the second roll is that Dice 1 must be 6 while Dice 2 must be 5 so that 6x5=30 </span>

<span>That is the only two ways out of 36 different combinations that can be made by rolling to Die. Therefore the probability is 2 out of 36

In ΔTUV, t = 410 cm, ∠U=27° and ∠V=78°. Find the length of v, to the nearest 10th of a centimeter.
telo118 [61]

Answer:

v \approx 415.2\,cm

Step-by-step explanation:

The angle T is:

\angle T = 180^{\circ} - 27^{\circ} - 78^{\circ}

\angle T = 75^{\circ}

Now, the length of v is determine by the Law of Sines:

\frac{410\,cm}{\sin 75^{\circ}} = \frac{v}{\sin 78^{\circ}}

v = (410\,cm)\cdot \left(\frac{\sin 78^{\circ}}{\sin 75^{\circ}} \right)

v \approx 415.2\,cm

The sum of three numbers is 125. The first number is 7 more than the first. The third number is 4 times the second.What are the
xenn [34]

Answer:

15, 22, 88

Step-by-step explanation:

I assume you mean the second number is 7 more than the first.  Write the system of equations:

x + y + z = 125

y = x + 7

z = 4y

Substitute the third equation into the first.

x + y + 4y = 125

x + 5y = 125

Substitute the second equation.

x + 5(x + 7) = 125

6x + 35 = 125

6x = 90

x = 15

Solve for the other variables.

y = 22

z = 88
