(x+2)(4+y)(5+6)(2+x)(4+0.5x)

combine like terms

(x+2) (4+y) (11) (x+2) (4+.5x)

11(x+2)^2 (4+y)(4+.5x)

distribute

11(x^2 +4x+2) (16+4y+2x+.5xy)

(11x^2+44x+22)(16+4y+2x+.5xy)

5.5 x^3 y + 22 x^3 + 66 x^2 y + 264 x^2 + 198 x y + 792 x + 176 y + 704

top answer row

315 E7 so a 5 in that box.

A mosquito is walking at random on the nonnegative number line. She starts at $1$. When she is at $0$, she always takes a step $

nikitadnepr [17]

Answer:

The expected number of times is 4.

Step-by-step explanation:

Looking at the question, we see that this follows a geometric distribution because it is asking for the expected number of trials hat will bring about the FIRST SUCCESS. The probability of success is

$\frac{1}{4}$

Since it is a geometric distribution, we know that the expected value of a random variable X, E(X) that follows a geometric distribution is given as:

E(X) = 1/p where p is the probability of success.

Therefore, the expected number of times will be

E(X) = 1/(1/p) = 1/(1/4) = 4.

Hence, the expected number of times is 4.

What is equivalent to 5(6×+3y)

meriva

Answer:

3*y/5-(6)=0

Step-by-step explanation:

Simplify —

Equation at the end of step 1 :

(3 • —) - 6 = 0

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 5 as the denominator :

6 6 • 5

6 = — = —————

1 5

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3y - (6 • 5) 3y - 30

———————————— = ———————

5 5

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

3y - 30 = 3 • (y - 10)

Equation at the end of step 3 :

3 • (y - 10)

———————————— = 0

Step 4 :

When a fraction equals zero :

4.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

3•(y-10)

———————— • 5 = 0 • 5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

3 • (y-10) = 0

Equations which are never true :

4.2 Solve : 3 = 0

Which is a stretch of an exponential decay function? f(x) = one-fifth (one-fifth) superscript x f(x) = one-fifth(5)x f(x) = 5one

vitfil [10]

The exponential function that represents a stretch of a decay function is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

$y = ab^x$ .

In which:

a is the initial value.

b is the rate of change.

It represents a stretch if a > 1, and a decay function if b < 1. Researching the problem on the internet, the correct option is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$
