The length of two sides of a triangle are 10, 15 find the range of possible lengths for the third side

Zepler [3.9K]

Answer:

Range for third side is

( 5 , 25 ) cm.

Step-by-step explanation:

As two sides of triangle are 10 and 15 ,

the third side would have to be less than the sum of other two sides i.e. less than 25 cm.

On the other hand if it is smaller one than this side plus side of length 10

should be greater than 15 and therefore

this side is greater than 15 − 10 = 5 cm.

Hence range is

( 5 , 25 )

Hope this answer helps you :)

The college student senate is sponsoring a spring break Caribbean cruise raffle, with proceeds going to the local homeless shelt

drek231 [11]

Answer:

The mathematical expectation of a student who purchases 10 tickets is -$39.65.

Step-by-step explanation:

A student that purchases 10 tickets out of 2900 has a probability of winning the cruise that can be calculated as:

$p=10/2900\approx0.00345$

Each ticket cost $5, so he has spent $50 for the 10 tickets.

Then, the expected value of this operation is equal to the expected value of the earnings (probability of winning the prize multiplied by the value of the prize), minus the costs:

$E(X)=p\cdot R-C\\\\E(X)=0.00345\cdot3000-50=10.35-50=-39.65$

The mathematical expectation of a student who purchases 10 tickets is -$39.65.
