Answer:
The one that has the lowest point at 5 and the highest point at 15
Step-by-step explanation:
That’s the range/ highest lowest values
Answer:
x = 4
Step-by-step explanation:
given f(x) = 11 then equate f(x) = 11 and solve for x
4x - 5 = 11 ( add 5 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4 ← value of x in the domain
Answer:
r = 1/10
Step-by-step explanation:
To get to one tenth of a number, the exponent of that number will be one tenth. In equation form, x^1/10=1/10x. Let x equal any real number. Hope I've helped <3
I think its 15+y or 15y im not surw
Answer:
a) P(t>3)=0.30
b) P(t>10|t>9)=0.67
Step-by-step explanation:
We have a repair time modeled as an exponentially random variable, with mean 1/0.4=2.5 hours.
The parameter λ of the exponential distribution is the inverse of the mean, so its λ=0.4 h^-1.
The probabity that a repair time exceeds k hours can be written as:

(a) the probability that a repair time exceeds 3 hours?

(b) the conditional probability that a repair takes at least 10 hours, given that it takes more than 9 hours?
The exponential distribution has a memoryless property, in which the probabilities of future events are not dependant of past events.
In this case, the conditional probability that a repair takes at least 10 hours, given that it takes more than 9 hours is equal to the probability that a repair takes at least (10-9)=1 hour.
