Add the given information to the table:

From the table, we can see that of the 423 of people that earned less than $50,000 per year, 262 thought that people's live would get better.

To calculate the number of people that earned less than $50,000 per year that thought people's lives would not get better, subtract 262 from 423 and place this number in the cell in column 2, row 3.

Continue like this to fill out the rest of the table, remembering to calculate the column and row totals:

An expression to show the number of people who will receive the text message after the fifth round is, 4 x 4⁵

In algebra, in sequence we study various progressions, one of the progression is geometric, in this progression for every two consecutive terms, the common ratio is the same.

Formula for nth term of G.P.,

Tₙ = a×rⁿ

where a is first term and r is common ratio

Given that,

Amber sends a text message to 4 people

Those 4 people send the text message to 4 more people, and so on

An expression to show the number of people who will receive the text message after the fifth round = ?

This process will follow a geometric progression,

Which have common ratio  = 4

First term a = 4

Fifth term =  ?

Here, n = 5

Tₙ = a × rⁿ

   =  4 x 4⁵

Step-by-step explanation:

17/16   is  just    17 ÷ 16    use calculator to fin = 1.0625

Answer:

1.06

Step-by-step explanation:

Step 1: divide numerator (1) by the denominator (16):

1 ÷ 16 = 0.0625

Step 2: add this value to the the integer part:

1 + 0.0625 = 1.0625. So,

1 1/16 = 1.0625

The result of 2/3 divided by 1/12 is equal to 8.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

To find the result of 2/3 divided by 1/12, we can use the following equation:

= 2/3 ÷ 1/12 = (2/3) × (12/1)
= 8

Since the multiplication of two numbers is equivalent to the division of their reciprocals, we can use the number line to represent the division as multiplication:

2/3 is located between 1/2 and 1 on the number line, and 1/12 is located between 0 and 1/10. Multiplying 2/3 by 12/1 is the same as moving 12 units to the right on the number line, which is equivalent to moving from 2/3 to 8.

So, the result of 2/3 divided by 1/12 is equal to 8.

Answer: x=-3 & x=3/2

Step-by-step explanation:

1. Simplify the expression

- Divide both sides by the same factor

9=2x^2+3x

2x^2 + 3x - 9 = 0

2. Use the quadratic formula

- Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

2x^2 + 3x - 9 = 0

a = 2

b = 3

c = -9

x = √-3±3^2−4⋅2(−9)/2⋅2

3. Simplify, again.

- Evaluate the exponent

- Multiply the numbers

- Add the numbers

- Evaluate the square root

x=−3±9/4

4. Separate the equations

- To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.

x=−3+9/4

x=-3-9/4

5. Solve

- Rearrange and isolate the variable to find each solution.

From the question, we have the following parameters that can be used in our computation:

P=W (1+a)/(1-a)

Cross multiply the equation

So, we have the following representation

P - Pa = W + Wa

Collect the like terms

This gives

Wa + Pa = P - W

So, we have

a(W + P) = P - W

What is a closed circle?

For numbers that are either less than or greater than (< or >), open circles are used. For numbers that are less than or equal to and greater than or equal to (≤ or ≥), closed circles are used.

A number line can be used to display inequality.

Given inequalities are

x > 3

x ≤5

x ≥-4

The inequity x > 3 contains a greater than symbol. Thus there will be an open circle at 3. x is greater than 3, so the arrow from the circle must show the numbers that are larger than 3.

The inequity x ≤5 contains a less than or equal symbol. Thus there will be a close circle at 5. x is less than or equal to 5, so the arrow from the circle must show the numbers that are less than 5.

The inequity x ≥-4  contains a greater than or equal symbol. Thus there will be a close circle at -4. x is greater than or equal to -4, so the arrow from the circle must show the numbers that are greater than -4.

Step-by-step explanation:

If Seth purchased a shiny key chain costing $0.34 and received $0.69 in change, then he gave the cashier $0.34 + $0.69 = $1.03.

Answer:

x - 0.69 = 0.34

x = 1.03

Therefore, Seth gave the cashier $1.03.

Answer:

x ≤ 217

Step-by-step explanation:

The mean is found by adding each time and dividing by the amount of attempts.

If the mean has to be no greater than 200s and there are five attempts, than the total five attempts should total to no more than 200*5=1000s

The total sum of the first four attempts is 192+206+194+191=783

x must be equal to or less than 1000 - 783 = 217
