La respuesta es 81.
Eso es porque
81*1= 81,
27*3=81,
y 9*9=81.
Answer:
Hey there! First you start with parenthesis! So distribute the 2 to 3x. There you get 6x. Now distribute to the 3. You get 6. Now you move the 2x over to the right side. Getting 30=4x+6.. Now move the 6 over to the 30. You get 24=4x..Now you divide, getting the answer 6! Hope this helps...
Answer is 6
Answer:
a) 0.0821
b) 0.0111
c) 0.0041
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

Either it lasts more 5 years or less, or it survives more than 5 years. The sum of the probabilities of these events is decimal 1. So

In all 3 cases, we want P(X > 5). So

In which

(a) lambda=.5


(b) lambda=0.9


(c) lambda=1.1


Answer:
5x+3y
Step-by-step explanation:
2x+3x=5x since they have the same variable.
y+2y
1y+2y u can put a 1 so that would be 3y
5x+3y
