Which table of values represents a linear function?

1 answer:

3 0

Answer: To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function

Step-by-step explanation: Example

x y

1 0

2 2

3 4

4 6

= Yes

x y

1 1

2 4

3 5

Answer:

$-\frac{9}{11}$

Step-by-step explanation:

$-\frac{6}{11} + -\frac{3}{11} = -\frac{6}{11} - \frac{3}{11} = -\frac{6+3}{11} = -\frac{9}{11}$

The commute time for people in a city has an exponential distribution with an average of 0.5 hours. What is the probability that

mamaluj [8]

Answer:

0.314 = 31.4% probability that a randomly selected person in this city will have a commute time between 0.4 and 1 hours

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

The probability that x is lower or equal to a is given by:

$P(X \leq x) = \int\limits^a_0 {f(x)} \, dx$

Which has the following solution:

$P(X \leq x) = 1 - e^{-\mu x}$

The probability of finding a value higher than x is:

$P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}$

In this question:

$m = 0.5, \mu = \frac{1}{0.5} = 2$

What is the probability that a randomly selected person in this city will have a commute time between 0.4 and 1 hours?

$P(0.4 \leq X \leq 1) = P(X \leq 1) - P(X \leq 0.4)$

In which

$P(X \leq 1) = 1 - e^{-2} = 0.8647$

$P(X \leq 0.4) = 1 - e^{-2*0.4} = 0.5507$

$P(0.4 \leq X \leq 1) = P(X \leq 1) - P(X \leq 0.4) = 0.8647 - 0.5507 = 0.314$

0.314 = 31.4% probability that a randomly selected person in this city will have a commute time between 0.4 and 1 hours

The graph of y=5/4x+1 is shown below. The coordinate (0,y) is a solution of the equation. Given the x–value of 0, what is the va

Nikitich [7]

the answer would be y =1 ,

substituting x with 0 would make the 5/4 disappear and leave you with 1, making it Y=1
