Answers: {4, 5}

========================================================

Explanation:

We have some number n and we're adding 1 to it to get n+1.

This n+1 is larger than 4. We want to find which values make n+1 > 4 true.

To find out, undo the operation "add 1" by subtracting 1 from both sides

n+1 > 4

n+1-1 > 4-1

n+0 > 3

n > 3

Anything larger than 3 will work. So that means {4,5} is the solution set from the original list of values.

For instance, if we tried n = 5, then

n+1 > 4

5+1 > 4 ... replace n with 5

6 > 4 ... true statement

But if we tried n = 1, then,

n+1 > 4

1+1 > 4

2 > 4 ... false; this shows n = 1 isn't in the solution set.

nignag [31]

Answer:

$46,000

Step-by-step explanation:

We just need to subtract all the annual payments from the salary to figure out her disposable income (which is the income remaining after deduction of taxes and social security charges).

So here's what we get

$60,000 - $3,000 - $5,000 - $6,000 = $46,000

The cost of health insurance is $1,200 per year. The cost of an operation for a dramatic injury is $500,000. The chances of some

SIZIF [17.4K]

Answer:

yes. The cost of the insurance is less than the probability cost of the operation

Step-by-step explanation:

yes. The cost of the insurance is less than the probability cost of the operation

The cost of health insurance = $1200

Cost of dramatic injury operation= $500,000

chances of need of operation= 47.3% over a 20 years period

the amount of pay insurance after 20 years= $20\times 1200= 240,00$

probable of cost operation= 0.473*500,00= $236,500

clearly the cost of insurance is less than the probable cost of operation.

Which equation results from taking the square root of both sides of (x 9)2 = 25? x 3 = ±5 x 3 = ±25 x 9 = ±5 x 9 = ±25.

kow [346]

The equation which is results from taking the square root of both sides of the provided equation is,

$(x+9)=\pm5\\$

<h3>What is the square root?</h3>

A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.

Let a number is <em>a. </em>Then this number in the form of square root can be written as,

$a=\sqrt{a}\times \sqrt{a}$

The given algebraic equation in the problem is,

$(x+ 9)^2 = 25$

Take the square root, in both sides,

$\sqrt{(x+ 9)^2} = \sqrt{25}\\\sqrt{(x+ 9)^2} = \sqrt{5^2}$

Cancel out the square root with the square of the number as,

$(x+9)=\pm5\\$

Hence, the equation which is results from taking the square root of both sides of the provided equation is,

$(x+9)=\pm5\\$

Suppose that many large samples are taken from a population and that the

Eddi Din [679]

Answer:

99.7% of the sample proportions will fall between 0.133 and 0.307.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 0.22

Standard deviation = 0.029

99.7% of the sample proportions will fall within which of the following intervals?

Within 3 standard deviations of the mean.

Lower end: 0.22 - 3*0.029 = 0.133

Upper end: 0.22 + 3*0.029 = 0.307

99.7% of the sample proportions will fall between 0.133 and 0.307.

How to tell if speed is increasing or decreasing calculus?

Reptile [31]

You will need data that logs the changes in speed from various, consecutive events. Which you can use to calculate the difference in speed and determine wether the speed is increasing or increasing.

Otherwise, you only need the initial and finak value to find the difference.

$final \: - \: initial \: = \: difference$
