Answers

$let \: x \: be \: the \: length \\ let \: y \: be \: the \: width$

$perimeter = 2x + 2y \\ area = xy$

$2x + 2y = 80 \\ xy = 380 \\ \\ x + y = 40 \\ xy = 380 \\ \\ x = 40 - y \\ (40 - y)y = 380 $

$40y - y {}^{2} = 380 \\ y {}^{2} - 40y + 380 = 0 \\ y {}^{2} - 40y + 400 = 20 \\ (y - 20) {}^{2} = 20 \\ y - 20 =± \sqrt{20} \\ y_{1}=20-√20≈15.52786\\ y_{2}=20+√20≈24.4721$

What is correlation coefficient and how to interpret it?

Correlation coefficient is a measure of how similar two datasets are acting.

The range of correlation coefficient is [-1, 1]

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated. One data increases, other data starts decreases in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

If the correlation coefficient comes out as 0, that means both the data sets are uncorrelated with respect to how we compare them.

When the correlation coefficient comes out > 0, that means both datasets' values are positively correlated.

If correlation coefficient comes out as 1, then the values grow exact similarly, in the same direction.

Given;

y = -0.4x + 98.3

When you increase your homework score by 1 point, you lose 0.4 points on your test.

-0.4x + 98.3 = 74

→ -0.4x = -24.3

→ x = 60.75 ≈ 61

Therefore, the correlation will be y=61.

Data on pull-off force (pounds) for connectors used in an automobile engine application are as follows: 79.3, 75.1, 78.2, 74.1, 73.9, 75.0, 77.6, 77.3, 73.8, 74.6, 75.5, 74.0, 74.7, 75.9, 72.9, 73.8, 74.2, 78.1, 75.4, 76.3, 75.3, 76.2, 74.9, 78.0, 75.1, 76.8.

(e) Calculate a point estimate of the proportion of all connectors in the population whose pull-off force is less than 73 pounds

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

79.3, 75.1, 78.2, 74.1, 73.9, 75.0, 77.6, 77.3, 73.8, 74.6, 75.5, 74.0, 74.7, 75.9, 72.9, 73.8, 74.2, 78.1, 75.4, 76.3, 75.3, 76.2, 74.9, 78.0, 75.1, 76.8

a) Calculate a point estimate of the mean pull-off force of all connectors in the population. State which estimator you used and why.

The mean can be used as a point estimate for the pull of force.

Using a calculator :

The mean(m) :

Σx /n = 1966/26

= 75.62 pounds

(b) Calculate a point estimate of the pull-off force value that separates the weakest 50% of the connectors in the population from the strongest 50%.

To obtain this, we calculate the median:

Median = 0.5(n + 1)th term

Median = 0.5(27)th term = 13.5

Take the 13th and 14th term:

(75.1 + 75.3) / 2 = 75.2 pounds

Using calculator ; the variance (s²) = 2.73815

The standard deviation (s) = √variance

s = √2.73815 = 1.655

(d) Calculate the standard error of the point estimate found in part (a). Interpret the standard error.

Standard Error = standard deviation / √n

Standard Error = 1.655 / √26

= 0.3245

(e) Calculate a point estimate of the proportion of all connectors in the population whose pull-off force is less than 73 pounds

Number of Proportions less than 73 pounds / number of samples

= 1 / 26

= 0.0385

1) Alexa Corp acquired several assets from Bonsai Corp. for $4,200,000. Assets acquired included a building, a stamping machine, and a forklift. An appraisal of the assets valued the building at $2,400,000, the press at $1,000,000, and the conveyor belt at $600,000. What is the value that will be assigned to each of these assets?

Answers

Answer:

Value assigned for Building = $2,520,000

Value assigned for Press = $1,050,000

Value assigned for Conveyor belt = $630,000

Step-by-step explanation:

Total appraisal value = Building + Press + Conveyor belt

Total appraisal value = 2,400,000 + 1,000,000 + 600,000

Total appraisal value = $4,000,000

Value assigned for Building = (2,400,000/4,000,000)*4,200,000

Value assigned for Building = $2,520,000

Value assigned for Press = (1,000,000/4,000,000)*4,200,000

Value assigned for Press = $1,050,000

Value assigned for Conveyor belt = (600,000/4,000,000)*4,200,000

Value assigned for Conveyor belt = $630,000

The amount in the bank after 2.5 years will be $241.875.

What is simple interest?

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. Mathematically -

$$A = P (1 + rt)$

{A} = final amount

{P} = initial principal balance

{r} = annual interest rate

{t} = time (in years)

Given is the amount deposited by Velvet in a bank for 2.5 years at a rate of 3%.

The amount in the bank after 2.5 years will be -

A = 225(1 + 0.03 x 2.5)

A = 225(1 + 0.075)

A = 225 x 1.075

A = 241.875

Therefore, the amount in the bank after 2.5 years will be $241.875.

The distribution of monthly charges for cellphone plans in the United States is approximately normal with a mean of $62 and a standard deviation of $18. What percentage of plans have charges that are less than $83.60?

Answers

About 88.49% of cellphone plans have charges that are less than $83.60.

How to determine the percentage of plans have charges that are less than $83.60?

To determine the percentage of plans that have charges less than $83.60, we need to find the z-score (z) using the given mean and standard deviation, and then look up the corresponding area under the normal distribution curve.

z = (x – μ) / σ

where x = 83.60, mean, μ = 62 and standard deviation, σ = 18

Thus, the z-score of $83.60 is:

z = (83.60 - 62) / 18 = 1.2

Using a standard normal distribution table, we can find that the area to the left of z = 1.20 is 0.8849 or 88.49% (check image attached).

Therefore, about 88.49% of cellphone plans have charges that are less than $83.60.

Which number has an 8 that is 1/10 the value of the 8 in 78?

Answers

Step-by-step explanation:

Step one:

Firstly we need to determine the place value of 8 in the term 78

in the term, we have 7 tens and 8 units

hence the place value of 8 in 78 is the units

Step two:

Now 1/10 of 8 is given as

0.1*8= 0.8

According to the problem statement, we are expected to find a number that has an 8 that is the same as 0.8.

Say 5.8, 6.8, 9.8

On a horizontal number line, the numbers grow as we walk to the right and drop as we move to the left.

A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is said to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers. So, on a number line, we may say that the value of numbers grows as we travel to the right.

A bakery sold 76 mocha cupcakes in a day, which was 95% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?

Answers

The total cupcakes the bakery sell that day is 80

How many total cupcakes did the bakery sell that day?

From the question, we have the following parameters that can be used in our computation:

Number of sales = 76

Proportion = 95%

This implies that

Number of sales = Proportion * Total number of cupcakes

Substitute the known values in the above equation, so, we have the following representation

76 = 95% * Total number of cupcakes

Divide both sides by 95%

Total number of cupcakes = 80
