Identify n in the equation below. Then name the property that is used.6 = 6 + n

A). 1, Identity property of addition

B). 0, Identity property of addition

C). 0, Commutative property of addition

D). 0, Multiplicative property of Zero

Answers

Answer 1
Answer: I believe it is B. A and D  you can cross them out. So you are left with B or C. The Identity Property is when you add any number to 0 then you will get the same number. So the answer is B. Hope all that made sense.

Set up the long multiplication.

543x36

Calculate 3 x 6, which is 18.
Since 18 is two-digit, we carry the first digit 1 to the next column.

Calculate 4 x 6, which is 24. Now add the carry digit of 1, which is 25.
Since 25 is two-digit, we carry the first digit 2 to the next column.

Calculate 5 x 6, which is 30. Now add the carry digit of 2, which is 32.
Since 32 is two-digit, we carry the first digit 3 to the next column.

Bring down the carry digit of 3.

Calculate 3 x 3, which is 9.

Calculate 4 x 3, which is 12.
Since 12 is two-digit, we carry the first digit 1 to the next column.

Calculate 5 x 3, which is 15. Now add the carry digit of 1, which is 16.
Since 16 is two-digit, we carry the first digit 1 to the next column.

Bring down the carry digit of 1.

10 Calculate 3258 + 16290, which is 19548


11 Therefore, 543 x 36 = 19548.

The answer is B.19548
B. 19,548 because a product is an aswer in amultipacation problem so you would have to multiply 543 x 36

A research firm wants to compute an interval estimate with 90% confidence for the mean time to complete an employment test. Assuming a population standard deviation of three hours, what is the required sample size if the error should be less than a half hour?

Answers

Answer:

n=97

Step-by-step explanation:

1) Notation and definitions

\sigma=3 population standard deviation known

Confidence=90% or 0.9

n sample size required (variable of interest)

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The sample mean have the following distribution

\bar X \sim N(\mu, (\sigma)/(√(n)))

2) Calculation for the sample size required

In order to find the critical value we need to take in count that we are finding the interval for the mean with the population deviation known, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by \alpha=1-0.90=0.1 and \alpha/2 =0.05. And the critical value would be given by:

z_(\alpha/2)=-1.64, t_(1-\alpha/2)=1.64

The margin of error for the sample mean interval is given by this formula:  

ME=z_(\alpha/2)(\sigma)/(√(n))    (a)  

And on this case we have that ME =\pm 0.5 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=((z_(\alpha/2) \sigma)/(ME))^2   (b)  

And replacing into equation (b) the values from part a we got:

n=((1.64(3))/(0.5))^2 =96.83  

And rounded up we have that n=97

Two times the sum of nine and a number is the opposite of 9.
Write an equation and solve.

Answers

The number is -27/2 if two times the sum of nine and a number is the opposite of 9 after applying the concept of the linear equation.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Two times the sum of nine and a number is the opposite of 9.

Let the number be x:

2(x + 9) = -9

2x + 18 = -9

2x = - 9 - 18

2x =- 27

x = -27/2

Thus, the number is -27/2 if two times the sum of nine and a number is the opposite of 9 after applying the concept of the linear equation.
