The Bureau of Labor Statistics (BLS) is the main fact-finding agency of the US government in the fields of labor economics and s

tatistics. Data from the Current Population Survey (CPS), conducted by the BLS and the Census Bureau, have been used to indicate a downward trend in retirement age. [Source: Gendell, M. (October 2001). Retirement age declines again in the 1990s. Monthly Labor Review, 124(10), 12-21.]
The following DataView tool displays a hypothetical data set consisting of annual income (as measured in thousands of dollars) and age of retirement for 100 retirees.
Use the tool to view the histogram of the retirement ages of the retirees, and answer the questions that follow. (Hint: Click either one of the Variable sliding panels in the bottom left-hand corner of the tool screen. Click the downward-pointing arrow next to Select Variable, and select the variable Retirement Age. Click the Histogram button in the middle of the left-hand side of the screen to view a histogram of its distribution.)

Determine whether y varies with x. If so, find the constant of variation and write the function rule.
ira [324]

Answer:  Yes, y does vary directly with x.

Constant of variation = 1/4

The function rule is  y = (1/4)x

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

Explanation:

Let's assume that y does vary directly with x.

If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.

Solving for k gets us k = y/x

For each row, divide the y value over the x value

  • row one: k = y/x = 14/56 = 0.25
  • row two:  k = y/x = 20/80 = 0.25
  • row three: k = y/x = 22/88 = 0.25

Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.

So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x

ICE Princess25 [194]

Answer:

The correct option is A.

Step-by-step explanation:

The given number is

\frac{5}{11}

Where 5 is dividend and 11 is divisor.

Since dividend is less than divisor we add a decimal place and the first zero. Notice the decimal point which has appeared on the answer line and by the dividend. It does not appear anywhere else.

Now the dividend is 50. Divide the number by divisor.

11\times 4=44

Subtract 44 from 50.

50-44=6

Therefore remainder is 6. Place a zero after 6.

Now the new dividend is 60. Divide the number by divisor.

11\times 5=55

Subtract 55 from 60.

60-55=5

Therefore remainder is 5.

\frac{5}{11}=0.454545

\frac{5}{11}\approx 0.45

Therefore option A is correct.
