Answer:

this is school work

Step-by-step explanation: sorry but you gotta figure this out yourself.

but, the thing is that you should figure out the stuff inside the (these -->) then figure out the rest step by step like this, x= what then try to understand y= what, then use them to answer the problem.

and if its like this 1(4x + 5y) that mean that 9xy times 1 is your answer, this is an example.

Determine the position of a given value.

$-58=-3+(n+1)(-5)$

$-58=-3-5n+5$

$-58=2-5n$

$-60=-5n$

$-60/5=-5n/5$

$n=12$

$-58 \ is \ in \ the \ 12th \ position$

Pls help with this I don’t understand

Bas_tet [7]

It’s phrased very weird, but I believe I have it figured out.

On the map, there distance of the race is 41.9 inches.

So, (41.9)(400) = 16760 feet

How do you solve this math problem-2(x+3y)=18

ss7ja [257]

Greetings!

Solve for <em>x</em>.
$-2(x+3y)=18$
Distribute the Parenthesis. <em>How?</em> Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
$(-2)*x+(-2)*3y=18$
$-2x-6y=18$
Add 6y to both sides.
$(-2x-6y)+6y=(18)+6y$
$-2x=18+6y$
Divide both sides by -2.
$(-2x)/-2=(18+6y)/-2$
The Answer Is:
$x=-9-3y$
$x=-3y-9$

Hope this helps.

Occasionally an airline will lose a bag. Suppose a small airline has found it can reasonably model the number of bags lost each

julia-pushkina [17]

Answer:

a) The probability that the airline will lose no bags next monday is 0.1108

b) The probability that the airline will lose 0,1, or 2 bags next Monday is 0.6227

c) I would recommend taking a Poisson model with mean 4.4 instead of a Poisson model with mean 2.2

Step-by-step explanation:

The probability mass function of X, for which we denote the amount of bags lost next monday is given by this formula

$P(X=k) = \frac{e^{-2.2} * {2.2}^k }{k!}$

$P(X=0) = \frac{e^{-2.2} * {2.2}^0 }{0!} = 0.1108$

The probability that the airline will lose no bags next monday is 0.1108.

b) Note that $P(X \in \{0,1,2\} = P(X=0) + P(X=1) + P(X=2)$ . And

$P(X=0)+P(X=1)+P(X=2) = e^{-2.2} * (1 + 2.2 + 2.2^2/2) = 0.6227$

Therefore, the probability that the airline will lose 0,1, or 2 bags next Monday is 0.6227.

c) If the double of flights are taken, then you at least should expect to loose a similar proportion in bags, because you will have more chances for a bag to be lost. WIth this in mind, we can correctly think that the average amount of bags that will be lost each day will double. Thus, i would double the mean of the Poisson model, in other words, i would take a Poisson model with mean 4.4, instead of 2.2.
