It's an identity if it has infinite solutions and everything is right, which would mean that if both sides of the equation are equal after eliminating the variable then the variable does not matter and it will always be equal. If it is not equal after eliminating the variable then that means that no matter what the variable is, it does not matter and the equation will have no solution

Between which two consecutive whole numbers does the root of 59 lie​
IrinaK [193]

Answer:

Step-by-step explanation:

¿Entre que números naturales consecutivos se encuentra cada raíz?

Bueno en este caso debes empezar por el 1 en adelante, pero solo sucede en números impares consecutivos. Solamente debes sumar 1,3,5,7,9,11,13,15,17,19 ..... en adelante, y en cada suma de cada sucesión encontraras un cuadrado. Ojo solo sumando en orden, tampoco sumarás 3+9, ya que te dará 12 y 12 No tiene raíz.

1+3=4,√4=2

4+5=9, √9=3

9+7=16, √16=4

16+9=25, √25=5

25+11=36, √36=6

36+13=49, √49=7

49+15=64, √64=8

64+17=81, √81=9

81+19=100, √100=10

............................................................................................................

A SI CONSECUTIVAMENTE SIEMPRE OBTENDRÁS CADA RAÍZ  

¿Entre que números naturales consecutivos se encuentra cada raíz?

R= En los número impares consecutivos, comenzando por el 1 en adelante.

A multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered b
yaroslaw [1]

Answer:

Therefore, the probability is P=0.0084.

Step-by-step explanation:

We know that  a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.

Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.

We calculate  the probability of getting exactly 6 correct answers.

n=9 and k=6.

P=C_k^n\cdot p^k\cdot q^{n-k}\\\\P=C_6^9\cdot 0.25^6\cdot 0.75^3\\\\P=84\cdot 0.0001\\\\P=0.0084

Therefore, the probability is P=0.0084.
