Mr. Wilson has $3,000 in his bank account. Ms. Nelson has 10 times as much money in her bank account as Mr. Wilson has in his ba

laiz [17]

Since Mr. Wilson has $3,000 and Ms. Nelson has 10 times more than that, we can set up a basic equation determining how much money Ms. Nelson has.

$(10)(3000)=30000$

Ms. Nelson has $30,000 while Mr. Wilson has only $3,000.

An opera house has a seating capacity of 872 people with each ticket costing 50 Rupees .If the opera house is running for 15 day

Nataly_w [17]

Answer:

654000 Rupees

Step-by-step explanation:

If we assume that the opera house was full every day then it would be 872 x 50 for the price of 1 day

872 x 50 = 43600

We multiple that number by the amount of days open so is would be 43600 x 15

43600 x 15 = 654000

Therefore it will make 654000 Rupees

Factor completely 2x5 + 10x4 − 22x3.

Luba_88 [7]

Given equation is :

$2x^{5}+10x^{4}-22x^{3}$ =0

Taking out $2x^{3}$ common we get,

$x^{2}+5x-11$ =0

Now solving this we get,

As 11 is not factor-able, we will solve it using the formula,

$x=\frac{-b+\sqrt{b^{2}-4ac}}{2a}$

a=1 b=5 and c=-11

we get,

$x=\frac{-5+\sqrt{69} }{2}$ and $x=\frac{-5-\sqrt{69} }{2}$

The Megasoft company gives each of its employees the title of programmer (P) or project manager (M). In any given year 70% of pr

Ne4ueva [31]

Answer:

it will take a programmer about 16.67 times to work before they are fired

Step-by-step explanation:

From the information given;

The transistion matrix for this study can be computed as:

P M X

P 0.7 0.2 0.1

M 0 0.95 0.05

X 0 0 1

where;

The probability that the programmer remains a programmer = $(P *P)$

The probability that the programmer turns out to be a manager = $(P*M)$

The probability that the programmer is being fired = $(P*X)$

Thus, the required number of years prior to the moment being fired for an employee y(P), for programmer and y(M) for manager is represented by ;

$y(P)=1+0.7y(P)+0.2y(M)$

$y(M)=1+ 0.95y(M).$

$0.05y(M)=1$

y(M) = $\dfrac{1}{0.05}$

y(M) =20

y(P)=1+0.7y(P)+0.2y(M)

y(P) - 0.7y(P) = 1 + 0.2y(M)

0.3y(P) = 1 + 0.2(20)=1+4

0.3y(P) = 1 + 4

0.3y(P) = 5

$y(P)=\dfrac{5}{0.3}$

$y(P)=16.67$

Therefore, it will take a programmer about 16.67 times to work before they are fired
