Answer:

16.6 feets .

Step-by-step explanation:

Length of wire = 30 feets

Distance between base of tree and ground = 25 feets

Height of tree, h

Using Pythagoras rule :

h² = 30² - 25²

h² = 900 - 625

h² = 275

h = sqrt(275)

h = 16.583

h = 16.6 feets

Height of tree is 16.6 feets

If one factor of x2 2x â€" 24 is (x 6), what is the other factor? (x 8) (xâ€"8) (x 4) (xâ’4).

FrozenT [24]

The correct question is; x² + 2x - 24

The other factor of x² + 2x - 24 asides (x+6) is; (x-4)

The expression given can be factorised as follows;

x² + 6x -4x - 24

x(x+6) -4(x+6)

(x+6) (x-4).

Consequently, the other factor of the expression is (x-4).

Assume that the number of customers who arrive at a water ice stand follows the Poisson distribution with an average rate of 6.4

Nady [450]

Answer:

18.88% probability that three or four customers will arrive during the next 30 minutes

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.

Average rate of 6.4 per 30 minutes.

This means that $\mu = 6.4$

What is the probability that three or four customers will arrive during the next 30 minutes?

$P = P(X = 3) + P(X = 4)$

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

$P(X = 3) = \frac{e^{-6.4}*(6.4)^{3}}{(3)!} = 0.0726$

$P(X = 4) = \frac{e^{-6.4}*(6.4)^{4}}{(4)!} = 0.1162$

$P = P(X = 3) + P(X = 4) = 0.0726 + 0.1162 = 0.1888$

18.88% probability that three or four customers will arrive during the next 30 minutes
