Answer:

Option B. is the answer.

Step-by-step explanation:

In the table, elevation is the input and amount of snowfall is the output.

It means when we put the value of elevation in the given function that represents the whole relation, we get the value of snowfall.

To represent any function for each value of input we should get a different value for output. In this situation each amount of snowfall is paired with one elevation.

Therefore Option B. is the answer.

You work with the office of city planning which is currently evaluating a new contract for a major highway. The chosen contracto

Ipatiy [6.2K]

Answer:

0.5488 = 54.88% probability that there are no defects in the completed highway.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

The portion of highway that your city is building is 30 miles long.

The mean is one defect per 50 miles. Since the highway is 30 miles, we have that:

$\mu = \frac{30}{50} = 0.6$

What is the probability that there are no (0) defects in the completed highway?

This is P(X = 0). So

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-0.6}*0.6^{0}}{(0)!} = 0.5488$

0.5488 = 54.88% probability that there are no defects in the completed highway.

Is this the right answer

Nata [24]

All internal angles in a quadrilateral add to 360

so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
