Answer:

480

Step-by-step explanation:

First add the numbers in the table together and put the total as a denominator in a fraction then the amount of times 2 odd numbers appeared as the numerator then put another fraction with 2,000 as the denominator and divide 2,000 by the total then multiply the numerator by that answer to get the correct answer.

A sequence consists of the positive odd integers. What is the sum of the first 12 terms of the sequence?

Volgvan

Answer:

A

Step-by-step explanation:

The sequence of positive odd numbers is

1, 3, 5, 7, ......

This is an arithmetic sequence with common difference d

d = 3 - 1 = 5 - 3 = 7 - 5 = 2

The sum to n terms of an arithmetic sequence is

$S_{n}$ = $\frac{n}{2}$ [2a + (n - 1)d ]

where a is the first term

here a = 1, d = 2, n = 12, hence

$S_{12}$ = $\frac{12}{2}$ [1 + (11 × 2) ]

= 6 [ 2 + (11 × 2) ]

= 6 × 24 = 144 → A

4 consecutive numbers that add up to 8

Digiron [165]

Answer:

The answer top your question is: 1/2, 3/2, 5/2 and 7/2

Step-by-step explanation:

Data

4 consecutive numbers that add up to 8

First number = n

2nd number = n + 1

3rd number = n + 2

4th number = n + 3

Now, add them up n + n + 1 + n + 2 + n + 3 = 8

Simplify like terms

4n + 6 = 8

4n = 8 - 6

4n = 2

n = 2/4 = 1/2

First number = n = 1/2

2nd number = n + 1 = 1/2 + 1 = 3/2

3rd number = n + 2 = 1/2 + 2 = 5/2

4th number = n + 3 = 1/2 + 3 = 7/2

Simplify. (3/4√15) (16√5) A60√5 B 60√3 C 50√3

Andrew [12]

Answer: OPTION B

Step-by-step explanation:

You have the following expresion:

$(\frac{3}{4}\sqrt{15})(16\sqrt{5})$

Mulitply them, then:

$=12\sqrt{75}$

Now, descompose the number inside the square root into it primes factor to simplify the expression:

75=5*5*3=5²*3

Substitute:

$=12\sqrt{5^2*3}$

Simplify. Then, you obtain:

$=12*5\sqrt{3}$

$=60\sqrt{3}$
