4r+5=3r can also be written
4r=3r-5
1r=-5
Answer: the answer to this solution is 8.04
Express it as a decimal.
3/20 = 0.15 by division
then move the decimal point twice to the right and affix the percent symbol
thus, 15%.
Subtracting a negative means that you will add the number. Convert the symbols to get the following:
y + 10 = 12
Subtract 10 from both sides.
y = 2
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
