This is very simple expansion and can be written as 30,000 + 9,000 + 5

Further Explanation:

Data:

The number 3 , 9 005 is given.

We have to make its expansion this very easy expansion.

When the no of thousands place then 3 zero are attached and make its expansion form like this if number is at ten thousand’s place than there should add 4 zeros with it.

Solution:

Sol.

= 3 , 9005

= 3 0 0 0 0 + 9 0 0 5

= 3 0 0 0 0 +  9 0 0 0 + 5

Answer :

The answer of the expansion is 3 0 , 0 0 0 + 9 0 0 0 + 5.

I have do it as easy as I can I hope you all understand this and it will help you also in future. And you can easily do any expansion by following this method. I hope this is easy for you and all students who have to done with the expansion of numbers. This is very easy but with some care you can do it.

When expanding number, we should separate the numbers according to the places like the number 275 written in expanded form 200+70+5. So, in this question we must likely done like this. The number is 39,005 the sum that is written on expanded form is 30,000+9,000+5.

Calculate the equation of the line if two points are (1,6) and (5,0) Hint, you will have to find the slope of the line and then
motikmotik

Answer:

The equation is y=\frac{-3}{2} x-9

Step-by-step explanation:

First, you will have to find the slope of the two points.To do that, you will have to use the formula : m=\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }

Our points are (1,6) and (5,0)

We will have to substitute the points into the formula.

m=\frac{0-6}{5-1}

Then, we will simplify

m= \frac{-6}{4}

We could simplify that fraction into \frac{-3}{2}

So, our slope is \frac{-3}{2}

We will have to pick a coordinate point, and choose. I chose (1,6)

We will substitute the x-value and the y-value of the coordinate point, including our slope, to calculate the y-intercept.

The formula we will be using is y=mx+b

We will substitute in our values which will make it look like:

6=\frac{-3}{2} (1)+b

We will then multiply \frac{-3}{2} by 1 which will stay the same.

Then, we will multiply \frac{-3}{2} by 6 which will equal -9

-9=b

Hence, the equation for our line is y=\frac{-3}{2} x-9

Hope it helped:D

How do you simplify (25/a -a l) / (5+a)
andrey2020 [161]

Simplify the following:

(25/a - a l)/(a + 5)


Put each term in 25/a - a l over the common denominator a: 25/a - a l = 25/a - (a^2 l)/a:

(25/a - (a^2 l)/a)/(a + 5)

25/a - (a^2 l)/a = (25 - a^2 l)/a:

Answer: ((25 - a^2 l)/a)/(a + 5)

At a financial institution, a fraud detection system identifies suspicious transactions and sends them to a specialist for revie
labwork [276]

Answer:

a. E(X) = 54.4

b. E(X) = 2.5

c. P(Y=2) = .0116

Step-by-step explanation:

a.

    E(X) = np = .40 probability * 136 trials = 54.4 blocked transmissions

    To get the expected value, we simply multiply probability times number of trials. You can look at it in simple terms by thinking if there's a 50% chance of flipping heads and you flip a coin twice, in an ideal world you will have .5*2 = 1 head.

b.

    i. Let X represent the number of suspicious transmissions reviewed until finding the first blocked one. We will use a geometric distribution to model the "first" transmission. Whenever we're looking for the "first" time something happens, we use geometric.

   ii. E(X) = 1/p , according to the geometric model.

              = 1/.4 = 2.5.

       We expect that the specialist will review 2.5 suspicious transactions <em>on average </em>before finding the first transmission that will be blocked.

c.

    i. Let Y represent the exact number of blocked transmissions out of 10. We will use a binomial distribution to model the "fixed" number of transmissions. Whenever we're looking for a "fixed" number of times something happens, we use binomial.

    ii. P(Y=k) = (n choose k)(p^k)(q^n-k)

        P(Y=2) = (¹⁰₂)(.4^2)(.6^10-2)

                    = 45 (.4^2)(.6^10-2) = .0016

        As for calculator notation, the n choose k can be accessed on a TI-84 via MATH -> PRB -> nCr. It looks like 10 nCr 2 on the display.

        Hence the probability that two transactions out of ten will be blocked is .0016 by the binomial model.
