Answer:

  $6475.56

Step-by-step explanation:

The maturity value is ...

  A = P(1 +rt)

where P is the principal amount, r is the annual rate, and t is the number of years. For ordinary interest, a year is 360 days, so the number of years is 160/360 = 4/9.

The loan value is ...

  A = $6200(1 + 0.10×4/9) ≈ $6475.56

Stephen's loan has a maturity value of $6,475.56.

Step-by-step explanation:

Residual  for the 5th observation if =$500 and =$475 is  -$166.25 The consumption function C = 300 + 0.75i represents the relationship between consumption and income in a simple economy with no taxes. In this function, C is the dependent variable, while i is the independent variable.

To find the residual for the 5th observation, we need to first calculate the predicted value of consumption (C1 ) for the given value of income (i). We can do this by plugging the value of i into the consumption function and solving for C1 :

C1 = 300 + 0.75i

For the first scenario where i = $500, the predicted value of consumption is:

C 1= 300 + 0.75($500) = $675

To calculate the residual, we need to subtract the predicted value of consumption from the actual value of consumption (C):

Residual = C - C1+

For the 5th observation where C = $500, the residual would be:

Residual = $500 - $675 = -$175

This means that the actual value of consumption is $175 less than the predicted value based on the consumption function.

Similarly, for the second scenario where i = $475, the predicted value of consumption would be:

C1 = 300 + 0.75($475) = $641.25

And the residual would be:

Residual = $475 - $641.25 = -$166.25  

In both cases, the residuals are negative, indicating that actual consumption is less than predicted consumption. This could be due to factors such as unexpected changes in consumer behavior, fluctuations in the economy, or measurement errors in the data.

The equation for a consumption function in a simple​ economy, where there are no​ taxes, is given by C​ = 300 ​+ 0.75​i,  What is the residual for the 5th observation if =$500 and =$475?c denotes consumption and i denotes income.

The probability that the student chosen is an industrial engineer is approximately 0.4717, and the probability that the student is a civil or electrical engineering student is approximately 0.3396.

The total number of students in the class is:

Total number of students = 25 + 10 + 10 + 8 = 53

The probability of selecting an industrial engineering student is:

P(i) = number of industrial engineering students / total number of students

= 25 / 53

≈ 0.4717

To find the probability that the student is a civil or electrical engineering student, we can use the formula:

P(c or e) = P(c) + P(e) - P(c and e)

P(c) = number of civil engineering students / total number of students

= 8 / 53

≈ 0.1509

P(e) = number of electrical engineering students / total number of students

= 10 / 53

≈ 0.1887

Assuming there are no students who belong to both categories, we get:

P(c or e) = P(c) + P(e) - P(c and e)

= 0.1509 + 0.1887 - 0

≈ 0.3396

Answer:

x = 11.8

Step-by-step explanation:

Side a = 11.78983

Side b = 3

Side c = 10

Angle ∠A = 120° = 2.0944 rad = 2/3π

Angle ∠B = 12.731° = 12°43'50" = 0.22219 rad

Angle ∠C = 47.269° = 47°16'10" = 0.82501 rad

The answer for x is 11.8

Answer: 3,348 cubic inches

Step-by-step explanation:

1. Since we know that volume= length x width x height, then we can plug our values into this equation.

2. So, we would do volume= 9 x 12 x 21.

3. 9 x 12 = 108, and 108 x 21 =2,268.

4. Now that we have both of the volumes, we have to add them together.

5. 1,080 + 2,268 = 3,348

6. The combined volume is 3,348 cubic inches.

Answer:

0.599 or 0.6

Step-by-step explanation:

We will be using the alphabets M and N in this solution.

Let M be that one of the number is even

Let N be that the sum is 8

The sample space of these two dice when rolled is 36

Probability of 8 and even numbers is (4,4),(6,2),(2,6)

= 3/36 = 0.08333

Probability of sum of 8 is (4,4),(5,3)(3,5),(6,2),(2,6)

= 5/36 = 0.1389

P(M|N) = 0.08333/0.1389

\(y=-\frac{5}{4} x+2.\)

Step-by-step explanation:

1) slope-interception form is: y=s*x+i, where 's' and 'i' are slope and interception;

2) according to the condition s= -5/4, then the required equation is: y= -5/4 *x +i, where i - interception;

3) if to substitute (-4;7) into the required equation y= -5/4 *x +i, it is possible to calculate 'i':

7= -5/4*(-4)+i; ⇒i=2, then

\(4) \ finally, \ y=-\frac{5}{4}x+2.\)

Answer:

9m ×5m

Step-by-step explanation:

Area of a rectangle= length ×width

Let the width be W meters and the length be L meters.

2 equations can be written from the given information:

45= WL -----(1)

L= W +4 -----(2)

Substitute (2) into (1):

45= W(W +4)

Expand:

45= W² +4W

-45 on both sides:

W² +4W -45= 0

Factorise:

(W +9)(W -5)= 0

W+9=0 or W-5=0

W= -9 or W= 5

(reject)

Substitute W= 5 into (2):

L= 5 +4

L= 9

∴ The dimensions of the garden is 9m ×5m.

The number of people were 200 in the theater when it was full.

What is a theater?

In architecture, a theatre, usually spelled theatre, is a structure or area where a play can be conducted in front of spectators. The term comes from the Greek theatron, which means "a place of seeing." The actual performance usually takes place on a stage in a theatre.

Given that, the theater was full when the movie began.

76 people leave the theater before end the movie. At the end of the movie, there is 124 people left.

Apply algebraical operation that is addition to find the required answer.

Volume is a three-dimensional scalar quantity. As per the Cavaleri's principle the volume of both the figures will be the same.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

According to Cavalieri's principle, if two figures have the same height and cross-sectional area throughout each point along that height, they have the same volume.

The height of both the objects is 16 cm, also the base area of both the objects is 96 cm². As it can be observed that for both the object there base area is the same through out their height.

Hence, as per the Cavaleri's principle the volume of both the figures will be the same.

The data in the table can be modeled by this linear equation in slope-intercept form: y = 8x - 5.

The slope is 8, which means the wages earned increases at rate of 8 dollars per hour as the time increases.

The y-intercept is -5 and it represent the initial wages earned.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is represented by this mathematical expression;

y = mx + c

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (24.00 - 8.00)/(3 - 1)

Slope (m) = 16.00/2

Slope (m) = 8

At data point (1, 3), a linear equation in slope-intercept form for this line can be calculated as follows:

y - y₁ = m(x - x₁)

y - 3 = 8(x - 1)

y = 8x - 8 + 3

y = 8x - 5

Answer:

0.00621

Step-by-step explanation:

We solve the above question using the

Z score formula. This is given as:

z = (x-μ)/σ/√n

where

x is the raw score = 12.20 or earlier

This means x ≤ 12.20

μ is the population mean = 13.20

σ is the population standard deviation = 2

n is the random number of samples = 25

z = 12.2 - 13.2/2/√25

z = -1/2/5

z = -1/0.4

z = -2.5

Probability value from Z-Table:

P(x≤ 12.2) = 0.0062097

Approximately = 0.00621

Therefore, the probability of randomly selecting a sample of 25 children who stood on their own by the average age of 12.2 months or earlier is 0.00621
