A decimal in the wrong place can change the value of a number completely for example
0.5 can be converted to 50 cents or 1/2 but if you change the decimal 0.05 converts to 5% or 1/20.

The algebraic form of a sequence is 4n+1. write the sequence​
diamong [38]

Answer:

5, 9, 13, 17, 21, .....

Step-by-step explanation:

To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule

a₁ = 4(1) + 1 = 4 + 1 = 5

a₂ = 4(2) + 1 = 8 + 1 = 9

a₃ = 4(3) + 1 = 12 + 1 = 13

a₄ = 4(4) + 1 = 16 + 1 = 17

a₅ = 4(5) + 1 = 20 + 1 = 21

The proportion of a population with a characteristic of interest is p = 0.37. What is the standard deviation of the sampling dis
lukranit [14]

The standard deviation (SD) of a sample proportion obtained when the sample size is 1,600 is equal to 0.0121.

<h3>What is a sample proportion?</h3>

A sample proportion can be defined as the proportion of individuals in a sample that have a specified characteristic or trait.

Mathematically, sample proportion can be calculated by using this formula:

\hat{p} = \frac{x}{n}

Where:

  • x represent the number of individuals with a specified characteristic.
  • n represent the total number of individuals in a sample.

In Mathematics, the standard deviation (SD) of a sample proportion obtained when the sample size is 1,600 can be calculated by using this formula:

Standard deviation (SD) = √(p(1 - p)/n)

Substituting the given parameters into the formula, we have;

Standard deviation (SD) = √(0.37(1 - 0.37)/1,600)

Standard deviation (SD) = √(0.37(0.63)/1,600)

Standard deviation (SD) = √(0.2331)/1,600)

Standard deviation (SD) = √0.0001457

Standard deviation (SD) = 0.0121.

Write the equation of line in slope-intercept form. Line parallel to y=0.5x+3 that passes through the point (−9,12)
Sliva [168]

A line parallel to the given one will have the same slope, 0.5. For the purpose here, it is convenient to start with a point-slope form of the equation, then simplify. For slope m and point (h, k), the equation of the line can be written as

... y = m(x -h) +k

We have m=0.5, (h, k) = (-9, 12), so the equation is ...

... y = 0.5(x +9) +12

... y = 0.5x +16.5
