Write the first five terms of the arithmetic sequence. a1 = 9; d = -2

Answers

Answer:

nth term = 1 1/2n -1

Step-by-step explanation:

The arithmetic sequence formula is:

a n = a 1 + ( n – 1 ) d

Where: a n

is the nth term in the sequence

a 1

is the first term in the sequence

n

is the term you are solving for

d

is the common difference for any pair of consecutive numbers in the sequence.

First Term or  

n = 1 :

This is given in the problem.

a 1  =  9

Second Term or  

n = 2 :

Substitute  

2  for  n

in the formula and substitute the values from the problem giving:

a 2 = 9 + ( ( 2 – 1 ) × -2 )

a 2 = 9 + ( 1 × -2 )

a 2 = 9 +-2

a 2 = 7

Fifth Term or  n = 5 :

Substitute      in the formula and substitute the values from the problem giving:

a 5 = 9+ ( ( 5– 1 ) × -2 )

a 5 = 9 + ( 4 × -2 )

a 2 = 9 + -8

a 2 = 1  

Using this same process you should be able to determiner the

Answers

Using it's concept, it is found that the mean income in Sambala is of $87,571.43.

The mean of a data-set is the sum of all observations in the data-set divided by the number of observations.

In this problem, there are 7 observations: 35000, 46000, 68000, 300000, 57000, 41000 and 66000.

Hence, the mean is:

[tex]M = \frac{35000 + 46000 + 68000 + 300000 + 57000 + 41000 + 66000}{7} = 87571.43[/tex]

Answers

Answer:

x = 16

y = 70.4

Step-by-step explanation:

Two triangles are similar, so we can use the similarity ratio to so find the variables

(2.8)/(22.4) = (8.8)/y cross multiply expressions

197.12 = (2.8)*y divide both sides by 2.8

70.4 = y

use same operation to find x

(2.8)/(22.4) = x/128 cross multiply expressions

358.4 = (22.4)*x divide both sides by 22.4

16 = x

Answers

Answer:

w > -0.4

Step-by-step explanation:

Given the inequality expression, w – 0.7 > -1.1:

First, we must isolate the variable, w, by adding 0.7 to both sides of the inequality statement:

w – 0.7 + 0.7  >  –1.1 + 0.7

w > -0.4

Therefore, the correct ray is the empty circle with its ray pointing towards the right (Option 4). This implies that -0.4 is not included as an endpoint in the inequality.

Attached is a screenshot of the number line where it shows where the empty circle is located, along with the direction of the arrow.

option B is correct, the money Luna left with is $20.00-(3×2.25+3.85)

What is Expression?

An expression is combination of variables, numbers and operators.

Given that Luna goes to the convenience store with $20.00.

Luna buys 3 frozen drinks for $2.25 each and a snack for $3.85.

The cost for 3 frozen drinks will be 3×$2.25

The cost of snacks is $3.85.

To find the money left we have to subtract the amount spend for drinks and snack.

$20.00-(3×2.25+3.85)

Hence, option B is correct, the money Luna left with is $20.00-(3×2.25+3.85)

In a box there are 6 orange balls, 4 green balls and "x" blue balls. If the probability of drawing a blue ball is 1/3, what is the probability of drawing two blue balls?

Answers

Step-by-step explanation:

I assume it is meant to draw 2 blue balls in a row out of the full pool of balls (no other draws happen before or during this process).

tricky, your teacher.

I think the temptation is to simply say 1/3×1/3 = 1/9.

but is it ?

the probabilty to draw one blue ball out of the complete system (no ball missing) is

x / (6+4+x) = 1/3

x = (6+4+x)/3

3x = 6 + 4 + x = 10 + x

2x = 10

x = 5

so, we have a system of 6 orange, 4 green and 5 blue balls (15 all together) .

the probability at our first pull to draw a blue ball is the indicated 5/15 = 1/3.

but now, for the second ball, we have only 6 orange, 4 green and 4 blue balls in the pool (14 altogether).

and so the probability to draw a blue ball out of this is

4/14 = 2/7.

therefore, the probability to draw 2 blue balls is now the combination

1/3 × 2/7 = 2/21

aha ! so, it is a little bit less than the originally suspected probability of 1/9.

4²-9.5+4.5

Then we do figure out the exponent.

4² =  (4)(4) = 16

16-9.5+4.5

Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.

16-9.5 = 6.5
