Answer:

<h2>First graph.</h2>

Step-by-step explanation:

Notice that in the piecewise functions, both parts have opposite slopes 2 and -2, that means the lines are perpendicular.

Also, the negative slope line must intercept y-axis at (0,3).

The positive slope line must intercept y-axis at (0,-1).

Additionally, the function indicates that to every x-value less than 1, the function is a decreasing line. And, for every x-value greater or equal than 1, the function is an increasing line.

Therefore, the first graph, represents the given piecewise function, because it has all the characteristics indicated by the function.

Answer:

A.) -⅔

B.) 3/-2

Step-by-step explanation:

from 1 to -1 you have to go down 2

from 2 to -1 you have to go down 3

therefore your slope is -⅔

from 3 to 6 you go up by 3

from 1 to -1 you go down by 2

therefore your slope is 3/-2

THERE ARE 1,000 WORKERS IN A FACTORY . EACH WORKER WORKS 30 HOURS A WEEK AND IS PAID $5.50 AN HOUR . HOW MUCH DOES THE COMPANY H

stepan [7]

1 worker = 30 hours a week
1 worker = 30 x $5.50 a week = $165

1 worker = $165
1000 workers = 165 x 1000 = $165 000

Answer:

(a) The probability of more than one death in a corps in a year is 0.1252.

(b) The probability of no deaths in a corps over 7 years is 0.0130.

Step-by-step explanation:

Let X = number of soldiers killed by horse kicks in 1 year.

The random variable $X\sim Poisson(\lambda = 0.62)$ .

The probability function of a Poisson distribution is:

$P(X=x)=\frac{e^{-\lambda}\lambda^{x}}{x!};\ x=0,1,2,...$

(a)

Compute the probability of more than one death in a corps in a year as follows:

P (X > 1) = 1 - P (X ≤ 1)

= 1 - P (X = 0) - P (X = 1)

$=1-\frac{e^{-0.62}(0.62)^{0}}{0!}-\frac{e^{-0.62}(0.62)^{1}}{1!}\\=1-0.54335-0.33144\\=0.12521\\\approx0.1252$

Thus, the probability of more than one death in a corps in a year is 0.1252.

(b)

The average deaths over 7 year period is: $\lambda=7\times0.62=4.34$

Compute the probability of no deaths in a corps over 7 years as follows:

$P(X=0)=\frac{e^{-4.34}(4.34)^{0}}{0!}=0.01304\approx0.0130$

Thus, the probability of no deaths in a corps over 7 years is 0.0130.
