Jet001 [13]

Answer:

NO

Step-by-step explanation:

Note :

Consider a triangle with sides‘s length a , b and c

triangle inequalities state that we must have c - a < b < c + a

now , is the third side always the longest ?

the answer is NO: (let’s take a counter example )

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. Two marbles are chosen from
Kryger [21]

Answer:

The expression would give the probability that one marble is yellow and the other marble is red is,

P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)

Step-by-step explanation:

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. So in total there are 25 marbles.

Hence,

Probability of getting yellow ball = P(Y)=\dfrac{8}{25}

Probability of getting red ball = P(R)=\dfrac{5}{25}

Probability that one marble is yellow and the other marble is red is,

P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)=\dfrac{8}{25}\cdot \dfrac{5}{25}+\dfrac{5}{25}\cdot \dfrac{8}{25}=0.128

By what factor must you multiply a number in order to triple its square root?
LiRa [457]
To solve the problem shown above you must apply the following proccedure:

 1. Let's call:

 x: a number.
 f: the factor.

 2. Then, you have:

 √fx=3√x

 3. You must clear the factor "f" to calculate its value, as below:

 √fx=3√x
 (√fx)²=(3√x)²
 fx=9x
 f=9x/x

 4. Then, the factor is:

 f=9

 5. Therefore, b<span>y what factor must you multiply a number in order to triple its square root?
