Answer:

B. 4x^2=28x-112=0.

Step-by-step explanation:

Using area=length*width, 160=(2x+8)(2x+6).

Expanding, (2x+8)(2x+6)=4x^2+16x+12x+48.

Setting this equal to 160, 160=4x^2+28x+48, or 4x^2+28x-112=0.

Answer:

1.83% probability there are no car accidents on that stretch on Monday

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 time interval.

The number of accidents on a certain section of I-40 averages 4 accidents per weekday independent across weekdays.

This means that $\mu = 4$

What is the probability there are no car accidents on that stretch on Monday?

This is P(X = 0).

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

$P(X = 0) = \frac{e^{-4}*(4)^{0}}{(0)!} = 0.0183$

1.83% probability there are no car accidents on that stretch on Monday

slamgirl [31]

29.37 rounds to 29

109.96 rounds to 110

The rule is that if the decimal portion is 0.50 or higher, then you round up. Otherwise you round down.
