The United States Bureau of Labor Statistics (BLS) conducts the Quarterly Census of Employment and Wages (QCEW) and reports a variety of information on each county in America. In the third quarter of 2016, the QCEW reported the total taxable earnings, in millions, of all wage earners in all 3222 counties in America. Suppose that James is an economist who collects a simple random sample of the total taxable earnings of workers in 56 American counties during the third quarter of 2016. According to the QCEW, the true population mean and standard deviation of taxable earnings, in millions of dollars, by county are ?=28.29 and ?=33.493, respectively. Let X be the total taxable earnings, in millions, of all wage earners in a county. The mean total taxable earnings of all wage earners in a county across all the counties in James' sample is x??. Use the central limit theorem (CLT) to determine the probability P that the mean taxable wages in James' sample of 56 counties will be less than $33 million. Report your answer to four decimal places. P(x??<33)= Use the CLT again to determine the probability that the mean taxable wages in James' sample of 56 counties will be greater than $30 million. Report your answer to four decimal places. P(x??>30)=

The sum of three consecutive numbers is 318. What is the third number in the series?

Answers

Answer:

106

Step-by-step explanation:

x + x + 1 + x + 2=318

3x + 3=318

3x=318-3

3x=315

x=104 1st number

3rd no=104 + 2 = 106

Can Someone please explain how to solve this. The directions say, "Solve the system by graphing. Then check your solution."

1 step to drow the graph required in the condition;

2 step to find intersection point (this is the A point);

3 step, check stage, to solve the system of two equations.

4 to compare the results in step 2 and step 3.

A bag contains 10 marbles. Four of them are red, three blue, two white and one yellow. A marble is drawn at random. What is the probability it is not blue?

Answers

Probability =
(number of different successful results) / (number of all possible results) .

Number of marbles that are not blue = 7
Number of marbles in the bag = 10
Probability that one marble drawn at random is not blue = 7/10 = 70% .

For all probability questions of this type, the probability can be found as:
$P_(desired)=(desired)/(total)$

or, more simply:
$P_(x)=(n_(x))/(n_total)$

In this case:
$P_(notblue)=(notblue)/(total)$
$P_(notblue)=(red+white+yellow)/(red+blue+white+yellow)$
$P_(notblue)=(4+2+1)/(4+3+2+1)$
$P_(notblue)=(7)/(10) = 70\%$

the answer is -34
this is because you multiple both sides by -1 and that would make 34 negative and -j positive

-34

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of its length and it’s width . The perimeter is 22 meters and I it’s length is 2 meters more then twice it’s width. What’s its length?

Answers

Answer:

The length of this rectangle is 8m.

Step-by-step explanation:

The problem states that the perimeter of a rectangle is twice the sum of its length and it’s width. So

$P = 2*l + 2*w$

The problem also states that the perimeter is 22 meters. So:

$P = 22$

$2l + 2w = 22$ .

Also, it states that I is the length and it is 2 meters more then twice it’s width. So

$l = 2w + 2$

What’s its length?

$P = 22$

$2l + 2w = 22$

$2(2w+2) + 2w = 22$

$4w + 4 + 2w = 22$

$6w = 22 - 4$

$6w = 18$

$w = (18)/(6)$

$w = 3$

The width is 3m. The length is in function of the width, so:

$l = 2w + 2$

$l = 2*3 + 2$

$l = 8m$

The length of this rectangle is 8m.
