Brian rolls a number cube twice. What is the probability that the sum of the 2 rolls is less than 6 given that the first roll is

Alona [7]

If the first roll is a three, then the only chance of the sum of the two numbers being less than six is if you roll a 1 or a 2.
That is 2/6 chance, or simplified, a 1/3 chance.

I hope this Helps!

Set up the trig equation with the correct values plugged in that you would use to solve for h. (You do not need to solve)

Usimov [2.4K]

From the reference of the 18 degree angle, 'h' is the opposite side and 100 is the adjacent side.

The trig ratio which uses both the opposite and adjacent sides is the tangent.

tan(18) = opp/adj = h/100

Trig equation:
tan(18) = h/100

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally. How long will each k

Harman [31]

Answer:

Each knight will guard <u>288 minutes</u> in one day.

Step-by-step explanation:

Given:

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally.

Now, to find the minutes will each night spend on guard duty in one day.

As, in 1 hour there are 60 minutes.

Thus, in 24 hour there are 60 × 24 = 1440 minutes.

Total minutes for guarding = 1440 minutes.

So, there are knights ordered for guarding are = 5.

And each day's guard duty equally.

Now, to get the minutes will each night spend on guard duty in one day we divide the total minutes for guarding by number of knights that is 5:

$1440\div5$

$=288\ minutes.$

Therefore, each knight will guard 288 minutes in one day.
