Answer: B
Explanation: ONE triangle can be formed.
According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.
Here, the sides are 1 m, 2 m, and 2m. 1m + 2m = 3m > 2m (theorem followed) 2m + 2m = 4m > 1m (theorem followed)
Since, the triangle inequality theorem is followed, Hence, ONE triangle can be formed.

In this diagram, a rope is attached to a small pulley at the apex of an isosceles prism. What is the minimum length of the rope
madreJ [45]

Answer:

Minimum length of rope needed to span the sides of the prism is 10 units.

Step-by-step explanation:

Let us draw a perpendicular from apex to base BC,Let it be AD since ΔABC is isosceles triangle, that perpendicular will touch mid of base. That is BD=DC=\frac{6}{2}=3

Now we know the angle m∠ABC as 53.13°.

From ΔADC, cos(53.13)=\frac{DC}{AC} =\frac{3}{(\frac{r}{2} )}

                      cos(53.13)=\frac{6}{r}

                      r=\frac{6}{cos(53.13)} = 9.999≈10

Hence minimum length of rope needed to span the sides of prism is 10 units.

Answer + Explanation:

The Monty Hall problem is a famous problem in conditional probability and reasoning using Bayes' theorem.

How to explain the probability?

In the problem, you are on a game show, being asked to choose between three doors. Behind each door, there is either a car or a goat.

You choose a door. The host, Monty Hall, picks one of the other doors, which he knows has a goat behind it, and opens it, showing you the goat.

You know, by the rules of the game, that Monty will always reveal a goat. Monty then asks whether you would like to switch your choice of door to the other remaining door.

In conclusion, the solution is that switching will let you win twice as often as sticking with the original choice.

The correct answer for this question is:

The loan's effective rate that had the greater increase, relative to its nominal rate, and how much greater is its increase than that of the other loan is that 'loan H’s increase was 0.16 percentage points greater than Loan I’s.

To test whether an integer, $n$, is prime, it is enough to be sure that none of the primes less than or equal to the square root
IrinaK [193]

Answer:

the largest divisor is less than the square root of that number

Step-by-step explanation:

Pick any number between 900 and 950 . For example I choose 937 . Now taking the square root of 937 would give 30.61

So divide 937 with all the primes less  than 30.61

937/2, 937/3, 937/5,...................937/29

29 would be the largest divisor which is less than the square root of 937 .

29< 30.61

But if you check 937 does not divide wholly with any of the primes hence it is a prime number itself.

If any number such 925 is chosen and it gets divided wholly by another prime like 5

925 /5= 185  so it is not a prime number
