You take a sample of rents of 182 apartments in San Francisco and find that the mean rent is $4000 per month and the standard de

viation is $1000 per month. According to Chebyshev's Theorem, what percentage of the rents in your sample fall between $1000 and $7000 per month? At least 89%

Answer:

89%

Explanation:

according to Chebyshev's theorem, for any k > 1, at least [1 - (1/k^2)] of the data will lie within k standard deviations of the mean.Therefore, Chebyshev's theorem formula can be given as follows:

Chebyshev's theorem formula =  1 - (1/k^2) ...................... (1)

In order to fing k, we proceed as follows:

1. Subtract the mean of rents from the larger rent value,

That is, $7,000 - $4,000 = $3,000

2. Divide the difference of $3,000 above by the standard deviation to obtain k as follows:

k = $3,000 ÷ $1000 = 3

3. Substitute 3 for k in equation (1) as follows:

Chebyshev's theorem formula =  1 - (1/3^2)

                                                   = 1 - (1/9)

                                                    = 1 - 0.11

                                                    = 0.89

If we multiply 0.89 by 100, we have 89%.

Therefore, 89% of the rents in the sample will fall between $1000 and $7000 per month.

Answer: Between $2,000 and $6,000

Explanation:

The probability must be between $2,000 and $6,000, that is, k=3, the standard deviation of the mean.

∴ 1 - 1/k²=  1 - 1/3² = 9 - 1/9 = 8/9

Hence, 8/9 of 100% = 89%

The probability between $2,000 and $6,000 must be at least 89%

anzhelika [568]

Answer: B. Charlotte

Explanation:

Preference is given to people that live with the dependent so this puts William at the least priority because he doesn't live with Autumn thereby leaving Charlotte and her mother.

Preference is then given to the biological parents of the dependent which means that Diana is has second priority. Charlotte is therefore the the most preferred to claim her daughter as a dependent which would allow her greater tax deductions.

klemol [59]

The interference of personality or status differences is called personality traits, that is, a way developed by psychologists to organize different personalities according to certain dimensions.

<h3>The Big Five Personality Traits </h3>

This is one of the most accepted approaches today, which divides the personality into the following traits:

  • Opening
  • Conscientiousness
  • Extroversion
  • Agreeableness
  • Neuroticism

Each of the traits encompasses different personality facets that help identify which one individual has more or less of compared to another individual.

Therefore, today's organizations need to understand the personality traits of their employees through testing and analysis, to better understand the motivation of each individual and create an organizational culture based on diversity and development.

Neko [114]

Answer:

$2,000

Explanation:

Ms. Pear invested $12,000 in 1,000 shares of YZ Corporation. After the dividends she received and the stock split, she ended with 2,400 shares. Since she sold 400 shares, it represents 16.67% of her total shares (= 400 / 2,400). To determine the basis for the 400 shares she sold all we need to do is multiply 16.67% x $12,000 (initial investment) = $2,000

Darina [25.2K]

Answer:

Explanation:

Expected annual growth rate in dividends 7%

Dividend growth Model= Pv=Do(1+g)/Ke-g

present value = 1(1+7%) / 12%-7%

present value =1.07 /5%

present value =21.4

Expected annual growth rate in dividends 2%

Dividend growth Model= Pv=Do(1+g)/Ke-g

present value = 1(1+2%) / 12%-2%

present value =1.02 /10%

present value =20.4

Expected annual growth rate in dividends -1%

Dividend growth Model= Pv=Do(1+g)/Ke-g

present value = 1(1+(-1)%) / 12%-2%

present value =0.99/10%

present value =7.69
