A landlord is considering upgrades and repairs, including wood floors, kitchen tile, a new back door, and a repaired garage door. The landlord could do these things himself or hire a contractor. The contractor could finish the job in half the time but would charge more. The landlord wants to leave the choice of whether to actually upgrade the kitchen tile up to the optimization algorithm. How should this constraint be written if he uses the following scheme for decision variables? x1 = contractor works on wood floors x2 = landlord works on wood floors x3 = contractor works on kitchen tile x4 = landlord works on kitchen tile x5 = contractor works on back door x6 = landlord works on back door x7 = contractor works on garage door x8 = landlord works on garage door Group of answer choices x3+ x4≤ 1 x3+ x4= 1 x3- x4= 1 x3- x4≤ 1

Answers

Answer:

x3 + x4 ≤ 1

Step-by-step explanation:

Upgrades considered = wood floors, Kitchen tile, New back door and a repaired garage

The constraint of whether to upgrade the kitchen either by the landlord or by  a contractor can be represented with the scheme below:

x3 + x4 ≤ 1

The constraint is written this way because  only one scheme can be used at a time i.e when x3 = 1 , x4 = 0 and vice versa. also

note that both x3 and x4 can be = 0.  because the upgrade of the kitchen tiles is under probability and the landlord might decide not to upgrade the kitchen tiles hence both schemes ( x3 and x4 ) can be = 0

agreed to pay back $13,250 in 270 days. What exact interest rate was
she paying? (Round your answer to the nearest tenth of a percent.)

Answers

8.1% is the exact interest rate

The exact rate of interest is 8.11%.

What is rate of interest?

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

Given:

Arianna North borrowed $12,500

She agreed to pay back $13,250 in 270 days.

let x be the interest rate was she paying

x= 13250 - 12500

= 750

So, x= 750/ 12500 (270/ 365)

x% = 750/ 9,246.57

x% = 0.0811

x%= 8.11%

Hence, the exact rate of interest is 8.11%.

Anna takes 10 selfies every 12 minutes at this rate how many minutes for 25 selfie’s

Answers

Answer:

30 minutes.

Step-by-step explanation:

You can make a proportion, which would be 10 selfies : 12 minutes. The second one will be 25 selfies : x minutes.

They have to be equal, since it is given that the rate stays the same. So 10:12=25:x

A proportion can be written as a fraction, so 10/12=25/x.

Cross multiply, and you get 10*x=12*25, or 10x=300.

Now divide both sides by 10 to get x=30.

A market researcher collects a simple random sample of customers from a population of over a million​ customers that use a home improvement website. After analyzing the​ sample, she states that she has​ 95% confidence that the mean​ time customers spent on​ that website per day is between and minutes. Suppose that the population mean​ time customers spent on that website is minutes a day. Does this value of the population mean help to show that the confidence interval estimate is​ correct? Explain.

Answers

Answer:

No, because the population mean, μ, is not included within the confidence interval estimate.

Step-by-step explanation:

A (1 - α)% confidence interval for a population parameter can be used make inferences about a statistic test of the parameter.

Decision rule:

If the null value of the population parameter is included in the interval then the null hypothesis will not be rejected. And vice-versa.

In this case, a market researcher wants to determine whether the population mean​ time customers spent on that website is 13 minutes a day or not.

The hypothesis can be defined as follows:

H₀: The population mean​ time customers spent on that website is 13 minutes a day, i.e. μ = 13.

Hₐ: The population mean​ time customers spent on that website is different from 13 minutes a day, i.e. μ ≠ 13.

The 95% confidence interval that the mean​ time customers spent on​ that website per day is, (15, 50).

The 95% confidence interval for the population mean time does no consist of the null value. Thus, the null hypothesis will be rejected.

It can be concluded that the population mean​ time customers spent on that website is not 13 minutes. Since the 95% confidence interval consist of values more than 13 minutes, it can be said that the  mean​ time customers spent on that website is more than 13 minutes.

Thus, the answer is:

No, because the population mean, μ, is not included within the confidence interval estimate.

Mean of a given set of data = Sum of all observations ÷ Total number of observations

Mean of this data set = 88 + 82 + 97 + 76 + 79 + 92 + 65 + 84 + 79 + 90 + 75 + 82 + 78 + 77 + 93 + 88 + 95 + 73 + 69 89 + 93 + 78 + 60 + 95 + 88 + 72 + 80 + 94 + 88 + 74

Mean = 2729 ÷ 30

Mean = 82.4

Median = the middle observation in a given set of data

Median of these test scores = 60 , 65 , 69 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 78 , 79 , 79 , 80 , 82 , 82 , 84 , 88 , 88 , 88 , 88 , 89 , 90 , 92 , 93 , 93 , 94 , 95 , 95 , 97 .

Median = 82 + 82 / 2

= 164 ÷ 2

= 82

Median = 82

Mode = most frequently occurring number in a given set of data .

Mode of these test scores =

= 60 = 1 time

= 65 = 1 time

= 69 = 1 time

= 72 = 1 time

= 73 = 1 time

= 74 = 1 time

= 75 = 1 time

= 76 = 1 time

= 77 = 1 time

= 78 = 2 times

= 79 = 2 times

= 80 = 1 time

= 82 = 2 times

= 84 = 1 time

= 88 = 4 times

= 89 = 1 time

= 90 = 1 time

= 92 = 1 time

= 93 = 2 times

= 94 = 1 time

= 95 = 2 times

= 97 = 1 time

Mode = 88

Midrange = average of the largest and smallest number in a given set of data

Midrange of these test scores = 97 + 60 / 2

= 97 + 60 / 2

= 157 ÷ 2

= 78.5

Midrange = 78.5

Therefore , the correct option is :-

(d) Mean is 82.4 , median is 82 , mode is 88 , midrange is 78.5

2) Why is it that when you fill the venn diagram with the number of elements, you
always need to start from the intersection of all sets?

Answers

Answer:

This is because it is easier this way.

You avoid the problem of putting an element in one set and then realizing that the element also belongs to another set, then you must erase something in order to put the element in both sets. Starting with the intersection allows you to know where will be each set in the diagram, and in this way, the diagram should end up being more readable or "clean".

This may seem small, but being "clean" when doing math, will allow you to have an easier time dealing with a lot of problems. And also will be easier for other people when reading your equations and such.

a. Draw a histogram of the binomial distribution for the survey.
b. What is the most likely outcome of the survey?
c. What is the probability that at least 3 families have a family dinner four times per week?​

Answers

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Given n = 5, p = 0.58, and q = 0.42.

P(0) = ₅C₀ (0.58)⁰ (0.42)⁵⁻⁰ = 0.013

P(1) = ₅C₁ (0.58)¹ (0.42)⁵⁻¹ = 0.090

P(2) = ₅C₂ (0.58)² (0.42)⁵⁻² = 0.249

P(3) = ₅C₃ (0.58)³ (0.42)⁵⁻³ = 0.344

P(4) = ₅C₄ (0.58)⁴ (0.42)⁵⁻⁴ = 0.238

P(5) = ₅C₅ (0.58)⁵ (0.42)⁵⁻⁵ = 0.066

The most likely result is 3 families.

The probability of at least 3 families is:

0.344 + 0.238 + 0.066 = 0.648
