5y + 3 = 8y − 5 + 2y

Answers

Answer:

[tex] \fbox{y = 8/5 } [/tex]

Explanation:

[to solve for y, first use the properties of equality to simplify the equation]

5y + 3 = 8y − 5 + 2y

5y + 3 = (8y + 2y) – 5

[regroup the like terms of y together: commutative property of equality ; adding in a different order will still give you the same result]

5y + 3 = 10y – 5

[combine like terms]

5y + 3 = 10y – 5

[tex] \: \: \: \: \: \: -3 \: \: \: \: \: \: \: \: \: \: \: -3[/tex]

[subtract 3 from both sides in order to eliminate the constant term on the left side: subtraction property of equality]

5y = 10y – 8

–10y –10y

[subtract 10 from both sides in order to eliminate the variable term: subtraction property of equality]

-5y = -8

÷(-5) ÷(-5)

[divide both sides by -5 to cancel out the coefficient of y: division property of equality]

y = 8/5

Answers

Answer:

The career planning process is ongoing and sequential. Since it is fluid rather than chronological, you move to the next step only when you are ready to do so, and you may move back and forth between steps at any given time. The career planning process is also cyclic. When career change is desired anytime during your work life, you may repeat the process once again. Data from the U.S. Bureau of Labor Statistics indicates that the majority of members of the labor force will make three to four major changes in their career during their 35 to 45 years of working. Because human beings are complex, each of us has unique aspirations, goals, potential for development, and limitations. Although we can follow the same process, career planning outcomes must be individualized.

Step-by-step explanation:

Suppose a normally distributed set of stock prices with 3500 observations has a mean of 101 and a standard deviation of 10. Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be between the values 91 and 121.

Answers

Answer:

The number of observations in the data set expected to be between the values 91 and 121 is of 2853.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 101, Standard deviation = 10

Percentage of of observations in the data set expected to be between the values 91 and 121.

91 = 101 - 10

So 91 is one standard deviation below the mean.

121 = 101 + 2*10

So 121 is two standard deviations above the mean

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.

Of those 50% below the mean, 68% are between one standard deviation below the mean(91) and the mean(101).

Of those 50% above the mean, 95% are between the mean(101) and two standard deviations above the mean(121).

So the percentage of observations in this interval is of:

[tex]P = 0.5*0.68 + 0.5*0.95 = 0.815[/tex]

Number of observations in the interval

81.5% of 3500. So

0.815*3500 = 2853

The number of observations in the data set expected to be between the values 91 and 121 is of 2853.

2. Based on a poll of 1000 residents, a newspaper article claims that 62% of the residents in town favor the
development of a recreational park on the west side of town. A community action group interested in
preserving the environment claims that 45% of the town's residents favor the development of a recreational
park.
To determine whether the sample supports the population proportion, a simulation of 100 trials is run, each

Answers

Answer:

A). Estimate of population 0.61

(b) Margin of error = 0.07 The real population interval estimation is ± 7%.

c). Margin of error = 0.15

d) The real population's interval estimation is ± 15%

e). Yes, the action argument of the group is based on a half-range estimation of the true population. The reason that 62% ± 15% = 47%, or 77%, while 47% is similar to 45%, as the Collective action group states.

Step-by-step explanation:

For the poll of 1000 residents, a newspaper article claims that 62% of the residents is in favor of development of a recreational park has,

(a) The point estimate of the population, 0.62.(b) The interval estimate of the true population proportion is 0.76.(c) The interval estimate of the true population proportion using half range is 0.15.(d) Yes, the community action group's claim likely based on either interval estimate of the true population proportion.

What is margin of error?

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

(a)The point estimate of the population-

Based on a poll of 1000 residents, a newspaper article claims that 62% of the residents in town favor the development of a recreational park on the west side of town.

This will be equal to the population, which is 0.62.

(b) The interval estimate of the true population proportion

The margin of error of the population proportion is found using an estimate of the standard deviation.

The sample is 200 and population, is 0.62. Margin of error for z value 1.96 can be found using the following.

[tex]MOE=z\sqrt{\dfrac{p(1-p)}{n}}\\MOE=1.96\sqrt{\dfrac{0.62(1-0.62)}{200}}\\MOE=0.0672[/tex]

This gives the interval estimate of the true population proportion is 6.72%.

The minimum sample proportion from the simulation is 0.46 and the maximum sample proportion is 0.76.

The margin of error of the population proportion using the half the range can be given as,

[tex]MOE=\dfrac{0.76-0.46}{2}\\MOE=0.15[/tex]

The interval estimate of the true population proportion using half the range is 0.15.

(d) The community action group's claim likely based on either interval estimate of the true population proportion-

A community action group interested in preserving the environment claims that 45% of the town's residents favor the development of a recreational park.

As, the value of confidence interval is greater than 0.45. Thus, the community action group's claim likely based on either interval estimate of the true population proportion.

Hence, for the poll of 1000 residents, a newspaper article claims that 62% of the residents is in favor of development of a recreational park has,

A previous survey reported that 53% of respondents increased their portfolio value over the past 3 years. How large should a sample be if the margin of error is .03 for a 91% confidence interval

Answers

Answer:

A sample of 796 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this question, we have that:

[tex]\pi = 0.53[/tex]

91% confidence level

So [tex]\alpha = 0.09[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.09}{2} = 0.955[/tex], so [tex]Z = 1.695[/tex].

How large should a sample be if the margin of error is .03 for a 91% confidence interval

We need a sample of n, which is found when [tex]M = 0.03[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.695\sqrt{\frac{0.53*0.47}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.695\sqrt{0.53*0.47}[/tex]

[tex]\sqrt{n} = \frac{1.695\sqrt{0.53*0.47}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.695\sqrt{0.53*0.47}}{0.03})^{2}[/tex]

[tex]n = 795.2[/tex]

Rounding up

A sample of 796 is needed.

He estimates that his bucket holds 20 times that of his jug.
Work out an estimate of the capacity of his bucket.
Give your answer in litres.

Answers

Answer:

The capacity of bucket is 16 liters

Step-by-step explanation:

Let j be the quantity of water in the jug

Then

[tex]j = 800ml[/tex]

Let B be the quantity of water held by the bucket

Then t is given that the bucket holds 20 times of water than the jug

[tex]B = 20j[/tex]

Putting the value of j

[tex]B = 800(20) = 16000[/tex]

We also know that

1 liter = 1000 ml

In order to convert ml into liters, we have to divide the quantity by 1000

[tex]B = \frac{16000}{1000} = 16\ liters[/tex]

Hence,

The capacity of bucket is 16 liters
