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

Formula; I = PRT

The above formula is a simple interest formula, where

Values:

I=1920​, P=24,000​, R=0.04

Substitute I=1920​, P=24,000​, R=0.04 in the equation I = PRT

So, we have

1920 = 24000 * 0.04 * T

Evaluate the products

1920 = 960 * T

So, we have

T = 1920/960

Evaluate

T = 2

Hence, the value is 2

A) The slope is 3/2

B) The line in point-slope form: y = (3/2)*(x - 2) + 10

C) The line in slope-intercept form: y = (3/2)*x  + 7

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

Here the line goes through (2, 10) and (-2, 4), then the slope is:

a = (10 - 4)/(2 + 2) = 6/4 = 3/2

b) The line in point-slope form for a point (h, k) is:

y = a*(x - h) + k

So here we get:

y = (3/2)*(x - 2) + 10

c) Expanding the above equation we will get:

y = (3/2)*x - (3/2)*2 + 10

y = (3/2)*x  + 7

Answer:

a) Total preferred dividend = $37,020; total common stock dividend = $26,980.

b) Total preferred dividend = $12,340; total common stock dividend = $51,660.

C) see explanation section.

Explanation:

Requirement - A

If the preferred dividend is cumulative.

Common stock = $12 x 50,000 = $600,000

Preferred stock = $19.5 x 7,910 = $154,245

Given,

Retained Earnings = $240,000, and Dividend = $64,000.

Generally, cash dividend is distributed to the preferred and common stockholders. However, after paying the preferred stock, dividend is paid to the common stockholders.

Therefore, preferred dividend = $154,245 x 8% = $12,340 for 2019.

As the preferred dividend is cumulative, the preferred stockholders will get the dividend for 2017 and 2018 if there remains any extra dividend after giving for 2019.

For 2017 = $12,340

For 2018 = $12,340

For 2019 = $12,340

Total preferred dividend = $37,020.

Therefore, the total common stock dividend = $(64,000 - 37,020) = $26,980.

Requirement - B

If the preferred dividend is non-cumulative.

Therefore, preferred dividend = $154,245 x 8% = $12,340 for 2019.

As the preferred dividend is non-cumulative, the preferred stockholders will not get the dividend for 2017 and 2018 despite remaining extra dividend after providing for 2019.

Therefore, preferred dividend = $12,340

Common stock dividend = $(64,000 - 12,340) = $51,660.

Requirement - C

The common stock dividend is more in non-cumulative as the company does not pay the previous years' dividends to the preferred dividend. On the other hand, if the company pays the dividend for the last years', which is known as cumulative, the dividend will become less. Therefore, the common stockholders will get fewer dividends because of paying the previous years' dividend to the preferred stockholders.

The factors would cause a more favorable dividend for the common stockholders if preferred dividends were non-cumulative, not in arrears, and there is an increase of distribution of dividends.

Answer:

B- function 1, because it’s rate of change is 2

Step-by-step explanation:

the rate of change of function 2 can be found since it is in slope intercept form

y=mx+b and m is slope and in this case m is 1/2

1/2 is function 2 rate of change

To find function 1 rate of change we use y2-y1/x2-1

using (1,2) and (-1,-2)

-2-2/-1-1

-4/-2

2 is the slope of function 1

Function 1 has a greater rate of change so  B is correct

What is union and interaction?

Union of Disjoint Sets:

If A and B are two finite sets and if A ∩ B = ∅, then

n(A ∪ B) = n(A) + n(B)

In simple words if A and B are finite sets and these sets are disjoint then the cardinal number of Union of sets A and B is equal to the sum of the cardinal number of set A and set B.

Given,

total number of students = 97

students who like chocolate and vanilla flavors = 25

students who like strawberry and vanilla flavors  = 16

students who like chocolate and strawberry flavors = 17

students who like all three flavors = 9

students who do not like ice cream = 5

Let C,S,V represent the chocolate, strawberry, vanila

therefore,

n(C∪S∪V) = n(C) + n(S) + n(V) - n(C∩V) - n(V∩S) - n(C∩S) + n(C∩V∩S)

97 = n(C)+n(S)+n(S)-25-27-9-5

141 = 3n(C)

n(C)=48

n(S) = n(V) =n(C)-2

The perimeter of a triangle is 78 if QA=10. SQ=28, BR=15 and A is the midpoint of QR, B is the midpoint of RS, and C is the midpoint of SQ in triangle QRS.

In Euclidean geometry, any three non-collinear points define a unique triangle and, at the same time, a unique plane. In other words, the triangle is contained in just one plane, and every triangle is contained in at least one plane. There is just one plane and all triangles are enclosed in it if the entire geometry is merely the Euclidean plane; however, this is no longer true in higher-dimensional Euclidean spaces. Unless otherwise specified, this article is about triangles in Euclidean geometry, specifically the Euclidean plane.

Given,

In triangle QRS,  A is the midpoint of QR, B is the midpoint of RS, and C is the midpoint of SQ

Also given that,

QA=10

BR=15

SQ=28

QA=RA=10

BR=SB=15

Therefore, perimeter of the triangle=RQ+QS+RS

=(RA+QA)+(QS)+(RB+BS)

=(10+10)+(28)+(15+15)

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

slope = (y2 - y1)/(x2 - x1)

Here we have two points (2, 1) and (2, 0), then the slope is:

slope = (1 - 0)/(2 - 2) = 1/0 → ∞

So the slope is infinity, as the case for all vertical lines.

b) Why we can't write the linear equation in the traditional form?

The Mean measure should be used to summarize the data in all three problems.

What is the mean?

In mathematics, particularly statistics, there are several types of means. Each mean is used to summarize a specific group of data, often in order to better understand the overall value of a data set.

Generally,

For ratio and interval type of data, we use mean as the central tendency

For the ordinal type of data, we use the median as the central tendency

and For the nominal type of data mode is prefered.

Interval data:- In this type of data point lies in some interval on a scale.

Like temperature in degrees Fahrenheit, it has some range of value on the measurement scale of temperature.

Ratio Data:- It is similar to interval type of data but absolute zero is treated as the point of origin.No negative value

Example:- temperature in kelvin (0 is the origin)

Ordinal data:- It is of categorical type of data that is in the natural order and the distance between the two data is not known.

Example:- How you describe your last purchasing experiences,

1) Very Pleasant 2) Somewhat Pleasant 3) Neutral 4) Somewhat Unpleasant 5) Very Unpleasant.

Nominal data:- In this data is leveled or named without any quantitative value.

Example:- Colour of hair, gender, country, etc.

a)

In part (a) the data is ratio type.

Hence, the Mean is the best central tendency of measurement.

b)

In (b) part also ratio type of data.

Hence, the Mean is the best central tendency of measurement.
