The lifespan, in years, of a certain computer is exponentially distributed. The probability that its lifespan exceeds four years
kompoz [17]

Answer:

The correct answer is "0.300993e^{-0.300993x}".

Step-by-step explanation:

According to the question,

⇒ P(x>4)=0.3

We know that,

⇒ P(X > x) = e^{(-\lambda\times x)}

⇒     e^{(-\lambda\times 4)} = 0.3

∵ \lambda = 0.300993

Now,

⇒ f(x) = \lambda e^{-\lambda x}

By putting the value, we get

           =0.300993e^{-0.300993x}

Solve the equation 14x+7Y=28 for x
Jobisdone [24]

Answer:

x= 2-1/2

Step-by-step explanation:

14x + 7y = 28

SUBTRACT 7Y FROM BOTH SIDES (TO ISOLATE X)

14x=28-7y

DIVIDE BY 14 TO ISOLATE X

x= 2-1/2

The absolute value function is written f(x) = |x|. It is composed of the lines y = x and y = -x. Its domain is the real numbers
Katena32 [7]
1.
no, there will never be a negative y-value.  <span>y= |x| will always be nonnegative. |x| can be distance x is from 0 and a distance can never be negative.

</span>2.
you can define it as
y = |x| = x if x ≥ 0, -x if x < 0

absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"

example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does

if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.

for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does
