"An on-line electronics store must sell at least $5000 worth of computers and printers per day"

The bold faced words tell us greater than or equal to 5000

"The store can ship a maximum of 20 items per day"

The bold faced words tell us less than or equal to 20

We can automatically eliminate A and B since they don't have EQUAL sign in them. From C and D, we choose D because it correctly attaches the price of printers and computers to the respective variables (printers is p & computers is q). Choice C does this wrong!

Amy and Mary are playing a board game that uses game money if $5 and $10. At the end of the game, Amy has n bills worth $5 each

loris [4]

Answer:

5n + 10d represented the money spend by the Amy in playing board games of cost $5 and $10 .

Step-by-step explanation:

As given

Amy and Mary are playing a board game that uses game money if $5 and $10.

At the end of the game, Amy has n bills worth $5 each and d bills worth $10 each .

Total amount of n bills = 5n

Total amount of d bills = 10d

Thus

Total money spend by the Amy in playing board games = Total amount of n bills + Total amount of d bills

= 5n + 10d

Therefore 5n + 10d represented the money spend by the Amy in playing board games of cost $5 and $10 .

Each day, Robin commutes to work by bike with probability 0.4 and by walking with probability 0.6. When biking to work injuries

kvasek [131]

Answer:

64.65% probability of at least one injury commuting to work in the next 20 years

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 interval.

Each day:

Bikes to work with probability 0.4.

If he bikes to work, 0.1 injuries per year.

Walks to work with probability 0.6.

If he walks to work, 0.02 injuries per year.

20 years.

$\mu = 20*(0.4*0.1 + 0.6*0.02) = 1.04$

Either he suffers no injuries, or he suffer at least one injury. The sum of the probabilities of these events is decimal 1. So

$P(X = 0) + P(X \geq 1) = 1$

We want $P(X \geq 1)$ . Then

$P(X \geq 1) = 1 - P(X = 0)$

In which

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

$P(X = 0) = \frac{e^{-1.04}*1.04^{0}}{(0)!} = 0.3535
$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.3535 = 0.6465$

64.65% probability of at least one injury commuting to work in the next 20 years
