LAST QUESTION, WILL GIVE BRAINLIEST-What is the common ratio for the geometric sequence?

1 answer:

8 0

Divide any term by the previous one.

For instance, divide the second term over the first.

r = common ratio
r = (second term)/(first term)
r = (-6)/(24)
r = -1/4 ... don't forget to reduce fully

The common ratio is -1/4

This means we multiply each term by -1/4 (decimal form -0.25) to get the next term

Find the number of possible outcomes if the numbers 1 through 7 are written on different pieces of paper and placed in a hat. Tw

Anit [1.1K]

Answer:

The number of the possible outcomes are:

12,13,14,15,16,17

21,23,24,25,26,27

31,32,34,35,36,37

41,42,43,45,46,47

51,52,53,54,56,57

61,62,63,64,65,67

71,72,73,74,75,76

The total number of possible outcomes = 42

Step-by-step explanation:

Given that :

the numbers 1 through 7 are written on different pieces of paper; &

Two of these numbered pieces of paper are selected without replacement;

Also,

a 2-digit number is formed using the first number drawn in the tens place and the second number drawn used in the ones place.

Then:

if the first number drawn is 1 , then the possible outcomes will be :

12,13,14,15,16,17

If the first number drawn is 2; then the possible outcomes will be:

21,23,24,25,26,27

If the first number drawn is 3; then the possible outcomes will be:

31,32,34,35,36,37

If the first number drawn is 4; then the possible outcomes will be:

41,42,43,45,46,47

If the first number drawn is 5; then the possible outcomes will be:

51,52,53,54,56,57

If the first number drawn is 6; then the possible outcomes will be:

61,62,63,64,65,67

If the first number drawn is 7; then the possible outcomes will be:

71,72,73,74,75,76

The number of the possible outcomes are:

12,13,14,15,16,17

21,23,24,25,26,27

31,32,34,35,36,37

41,42,43,45,46,47

51,52,53,54,56,57

61,62,63,64,65,67

71,72,73,74,75,76

The total number of possible outcomes = 7 × 6 = 42

Morgarella [4.7K]

Answer:

x = 0

Step-by-step explanation:

here's the solution :-

=》 -13x - 2 = -10x - 2

=》 -13x + 10x = -2 + 2

=》 -3x = 0

=》 x = 0 ÷ -3

Find a a pair of numbers of both 4y-4x=48 and y= x-11

stich3 [128]

Answer:

There is no solution because the slopes of the line are the same.

Step-by-step explanation:

4y - 4x = 48

+ 4x + 4x Add 4x to both sides

4y = 4x + 48 Divide both sides by 4

y = x + 12

Now set both equations equal to each other since they equal y

x + 12 = x - 11

-x - x Subtract x from both sides

12 ≠ -11 No Solution

Please help me I’m so lost !!!!

Tasya [4]

Answer:

$4095$

Step-by-step explanation:

$\sum _{n=1}^63\left(4^{n-1}\right)\:$

$\sum _{n=1}^63\cdot \:4^{n-1}$

Compute general progression:

$\frac{3\cdot \:4^{\left(n+1\right)-1}}{3\cdot \:4^{n-1}}=4$

$r=4\\$

$a_1=3\cdot \:4^{1-1}$

$a_1=3$

nth term is computed by:

$r=4,\:a_n=3\cdot \:4^{n-1}$

plug in the values $n=6,\:\spacea_1=3,\:\spacer=4$ :

$=3\cdot \frac{1-4^6}{1-4}$

$=4095$

the length of a rectangle is three times its width ,if the width is x cm. write down an expression of length in term of x

Bezzdna [24]

Answer:

L = 3x cm

Step-by-step explanation:

For this problem, let's consider the relation that is stated:

Length is 3 times as much as the width. The width is x cm.

Mathematically we can say the following:

L = 3W

W = x cm

So we can say the following about the length:

L = 3W

L = 3(x cm)

L = 3x cm
