Answer:

ΔACD and ΔECB

Step-by-step explanation:

Because X is the midpoint of both AD and BE, then AD = BE.

SAS stands for side angle side meaning the triangles have to share equal sides, angle, and then side.

AC = EC, ∠C = ∠C, CD = CB

Answer: 82.5 - x = R sorry if I am wrong

Step-by-step explanation:

1. We know all the angles in a triangle add up to 180 degrees.

180 = x + x + 15 + R

2. Combine like terms

180 = 2x + 15 + R

3. Subtract 15 from both sides

165 = 2x + R

4. Divide both sides by 2

82.5 = x + R

5. Subtract x from both sides

82.5 - x = R

Answer:

$954.78

Step-by-step explanation:

Since it increases by 8.5%, all you have to do is multiply 879.98 by 1.085.

879.98 * 1.085 = $954.7783 = $954.78 (you always have to round to two decimal places with money)

AysviL [449]

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
