What are some differences between solving linear equations and solving quadratics?

Nat2105 [25]

Answer:

Linear functions are one-to-one while quadratic functions are not. A linear function produces a straight line while a quadratic function produces a parabola. Graphing a linear function is straightforward while graphing a quadratic function is a more complicated, multi-step process.

angle E and angle F are supplementary the measure of angle E is 54 more than the measure of angle F find the measures of each an

Ne4ueva [31]

The measure of angle F is 63° and the measure of angle E is 117°

<u>Step-by-step explanation:</u>

Given that E and F are supplementary angles which means that the sum of the angles is 180°.

Let the measure of angle F=x

given that the measure of angle E is 54 more than F

E=54+x

F+E=180°

x+54+x=180°

2x+54=180°

2x=180-54

=126°

x=126/2=63°

F=63°

E=F+54=63+54=117°

Answer:

18.04% probability that exactly 3 serious deviations and incursions will occur at LAX in a randomly selected year

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.

Suppose the mean number of deviations and incursions per year at the Los Angeles International Airport (LAX) is 2.

This means that $\mu = 2$

Find the probability that exactly 3 serious deviations and incursions will occur at LAX in a randomly selected year

This is P(X = 3).

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

$P(X = 3) = \frac{e^{-2}*2^{3}}{(3)!} = 0.1804$

18.04% probability that exactly 3 serious deviations and incursions will occur at LAX in a randomly selected year
