Answer: 20

Step-by-step explanation:

The number of ways to arrange n things in which a things are identical , b things are identical and so on...... is given by :-

\dfrac{n!}{a!b!......}

Given Word : ERROR

Total letters = 5

Here letter R is repeated 3 times.

Then, the number of  unique ways to arrange the letters in the word "ERROR " will be :-

\dfrac{5!}{3!}=\dfrac{5\times4\times3!}{3!}=20

Hence, the number of  unique ways to arrange the letters in the word "ERROR "=20

Find the value of the series
jekas [21]

Step-by-step explanation:

that is

sum(2^r) for r=1 to n, plus sum(1/2) for r=1 to n.

and that is

sum(2^r) + n/2 for r=1 to n.

2^r is a geometric sequence with 2 being the common ratio (every new term is created by multiplying the previous term by 2).

and since r is starting at 1, the first term a1 = 2.

the formula for the sum of a finite geometric sequence is

Sn = a1×(1 - r^n) / (1 - r)

with r being the common ratio .

so, in our case

Sn = 2×(1 - 2^n) / (1 - 2)

Sn = (2 - 2^(n+1)) / -1 = 2^(n+1) - 2

and so, in total we get

2^(n+1) - 2 + n/2 = 2^(n+1) + (n - 4)/2

Allisa [31]

Answer:

D, E, F

Step-by-step explanation:

The first step I would do is distribute the original equation. After distributing, the equation is now 8x² + 16xy. The first answer I see that matches this is D.

Then, after already eliminating A, B, and C, I look at E. I distribute the x and find out it is also equal to 8x² + 16xy.

Then, I look at F. After distributing again, it is also equal to 8x² + 16xy.
