The distribution of the annual incomes of a group of middle management employees approximated a normal distribution with a mean
kondor19780726 [428]

Answer:

68% of the incomes lie between $36,400 and $38,000.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ =  $37,200

Standard Deviation, σ = $800

We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.

Empirical rule:

  • Almost all the data lies within three standard deviation of mean for a normally distributed data.
  • About 68% of data lies within one standard deviation of mean.
  • About 95% of data lies within two standard deviation of mean.
  • About 99.7% of data lies within three standard deviation of mean.

Thus, 68% of data lies within one standard deviation.

\mu \pm \sigma\\=37200 \pm 800\\=(36400,38000)

Thus, 68% of the incomes lie between $36,400 and $38,000.

A first number plus twice a second number is 55. Twice the first number plus the second totals 1313. Find the numbers.
Sphinxa [80]
The answer: x=857 and y=-401

Set up the two equations

X+2y=55
2x+y=1313

Solve the system of equations by elimination

2x+y=1313
-2x-4y=-110

Add each of the corresponding terms together

-3y=1203

Divide by -3

Y=-401

Plug y back into one of the original equations

X+2(-401)=55
X-802=55
X=857
