Answer:

x = 26

Step-by-step explanation:

Since a triangle adds up to 180 degrees, we can do:

x + 4x - 5 + 55 = 180

5x + 50 = 180

5x = 130

x = 26

Step-by-step explanation:

Calculation for dividend per share of common stock for board of directors of Midwest Foods

First step is to find the dividends due to the preferred shareholders

Dividends due to the preferred shareholders will be calculated as:

Using this formula

Total Dividend =Dividend- (Preferred stock *Per share of preferred stock )

Where,

Dividend=$3,500,000

Preferred stock =$300,000

Per share of preferred stock =$2.85

Let plug in the formula

Total Dividend =$3,500,000-($300,000*$2.85)

Total Dividend =$3,500,000-$855,000

Total Dividend =$2,645,000

The second step is to find Dividend per share of common stock

Using this formula

Dividend per share of common stock=Total dividend/Shares of common stock

Where,

Total dividend=$2,645,000

Shares of common stock=$2,500,000

Let plug in the formula

Dividend per share of common stock=$2,645,000/$2,500,000

Dividend per share of common stock=$1.06 per share

Therefore the dividend per share of common stock for board of directors of Midwest Foods will be $1.06 per share

Answer:

There is 90% confidence that the proportion of the adult citizens of the nation that dreaded Valentine’s Day is between 0.214 and 0.286.

Step-by-step explanation:

The summary of the statistics from the information given is ;

At 90% confidence interval, 25​% dreaded​ Valentine's Day and the margin of error for the survey was 3.6 percentage points

SO;

[tex]C.I = \hat p \pm M.O.E[/tex]

[tex]C.I = 0.25 \pm 0.036[/tex]

C.I = (0.25-0.036 , 0.25+0.036)

C.I = (0.214, 0.286)

The 90% confidence interval for the proportion of the adult citizens of the nation that dreaded Valentine’s day is 0.214 and 0.286.

There is 90% confidence that the proportion of the adult citizens of the nation that dreaded Valentine’s Day is between 0.214 and 0.286.

Answer:

84%

Step-by-step explanation:

We find the z-score here

z= x-mean/SD = 32-40/8 = -1

So the probability we want to find is;

P(z>-1)

This can be obtained using the standard score table

P(z>-1) = 0.84 = 84%

[tex]\boxed{\frac{-3b^4 }{a^6 }}[/tex]

Step-by-step explanation:

[tex]\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}[/tex]

[tex]\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}[/tex]

[tex]-3 \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}[/tex]

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

[tex]-3 \times a^{-8-(-2)} \times b^{-3- (-7)}[/tex]

[tex]-3 \times a^{-8+2} \times b^{-3+7}[/tex]

[tex]-3 \times a^{-6} \times b^{4}[/tex]

Answer:

x=2

Step-by-step explanation:

3(x-2)-6x=4(x-5)

Distribute

3x -6  -6x = 4x -20

Combine like terms

-3x-6 = 4x-20

Add 3x to each side

-3x-6+3x = 4x-20+3x

-6 = 7x-20

Add 20 to each side

-6+20 = 7x-20+20

14 = 7x

Divide by 7

14/7 =7x/7

2=x

Answer:

Step-by-step explanation:

[tex]3(x - 2) - 6x = 4(x - 5)[/tex]

Distribute 3 through the parentheses

[tex]3x - 6 - 6x = 4(x - 5)[/tex]

Distribute 4 through the parentheses

[tex]3x - 6 - 6x = 4x - 20[/tex]

Collect like terms

[tex] - 3x - 6 = 4x - 20[/tex]

Move variable to L.H.S and change it's sign

[tex] - 3x - 4x - 6 = - 20[/tex]

Move constant to RHS and change it's sign

[tex] - 3x - 4x = - 20 + 6[/tex]

Collect like terms

[tex] - 7x = - 20 + 6[/tex]

Calculate

[tex] - 7x = - 14[/tex]

Divide both sides of the equation by -7

[tex] \frac{ - 7x}{ - 7} = \frac{ - 14}{ - 7} [/tex]

Calculate

[tex]x = 2[/tex]

Answer:

As x → - ∞ , y → - ∞ and as x→ ∞ , y → -∞

Step-by-step explanation:

f ( x ) = - 5x⁴ + 7x² - x + 9

Here, dominating term is ( -5x⁴ ) which has even exponent.

Now, as x → ∞ ⇒ - 5x ⁴⇒ - ∞ [ x⁴ → ∞ ]

⇔ f (x) → - ∞ [ -5x⁴ is dominating term ]

x→ ∞ , y → -∞

as x→ - ∞ , ( -5x⁴ ) → - ∞ [ x⁴ → ∞ ]

as x→ - ∞ , y → -∞

Hence, Option B is the correct option.

------------------------------------------------------------------

You just have to focus on leading term, which is the term that has highest exponent of variable, as in our case , it is -5x⁴.

And then find leading coefficient, whether it is positive or negative degree ( power of variable) and whether it is even number or odd number)

Then, if leading coefficient is negative and degree is positive then always y will approach -∞ .

Hope this helps...

Best regards!!

Answer:

As x goes to negative infinity, y goes to  - ∞

As x goes to infinity, y goes to  - ∞

Step-by-step explanation:

We need to look at the dominate term

-5x^4

As x goes to negative infinity

-5 *(- ∞) ^ 4 = -5 * ∞ = - ∞

As x goes to negative infinity, y goes to  - ∞

As x goes to  infinity

-5 *( ∞) ^ 4 = -5 * ∞ = - ∞

As x goes to infinity, y goes to  - ∞

Answer:

2 × 10 + 2 × 14

Step-by-step explanation:

The frame is given to have measurements 2 times that of the photograph's measurements. We also know that the photograph is given by dimensions being 5 inch by 7 inch. Therefore the measurements of the frame should be 5 [tex]*[/tex] 2, which = 10 inches, by 7 [tex]*[/tex] 2 = 14 inches.

So the dimensions of the frame are 10 inch × 14 inch. As the frame is present as a rectangle, the perimeter is given by two times both dimensions together. That would be represented by the expression " 2 × 10 inch + 2 × 14 inch. " In other words you can say that the expression is 2 × 10 + 2 × 14 - the expression that represents the perimeter of the frame.

Answer:

Step-by-step explanation:

Given that :

A web page is accessed at an average of 20 times an hour.

Therefore:

a. he rate parameter λ of the distribution of the time until the first hit = 20

b.  What is the expected time between hits?

Let consider E(Y) to be the expected time between the hits; Then :

E(Y) = 1/λ

E(Y) = 1/20

E(Y) = 0.05 hours

E(Y) = 3 minutes

(c.)  What is the probability that there will be less than 5 hits in the first hour?

Let consider X which follows Poisson Distribution; Then,

P(X<5) [tex]\sim[/tex] G(∝=5,  λ = 20)

For 5 hits ; the expected time will be :

Let 5 hits be X

E(X) = ∝/λ

E(X) = 5/20

E(X) =1/4

E(X) = 0.25 hour

E(X) = 15 minutes

From above ; we will see that  it took 15 minutes to get 5 hits; then

[tex]P(\tau \geq 0.25) = \int\limits^{\alpha}_{0.25} \dfrac{\lambda^{\alpha}}{\ulcorner^{\alpha}} t^{a\pha-1} \ e^{-\lambda t} \, dt[/tex]

[tex]P(\tau \geq 0.25) = \int\limits^{5}_{0.25} \dfrac{20^{5}}{\ulcorner^{5}} t^{5-1} \ e^{-20 t} \, dt[/tex]

Answer:

4611/11515

Step-by-step explanation:

1/(1×3)- 1 times 3 simply equals 3. so the answer would be 1/3.

1/(3×5)- 3 times 5 simply equals 15. so the answer would be 1/15.

1/(47×49)- 47 times 49 is 2303. so the answer would be 1/2303.

after all this you find the common deonomator. The common denominator is 34545. 34545 divided by 3 equals to 11515 so you  muliplty that number by 1/3.  34545 divided by 15 equals to 2303 so you  muliplty that number by  1/15.

34545 divided by 2303 equals to 15 so you multiply that number by 1/2303. After adding all that together you get 13833/34545. However after you simplify that number you get 4611/11515

Answer: [tex]\dfrac{60}{143}[/tex]

Step-by-step explanation:

Given,  A class has five boys and nine girls.

Total students = 5+9=14

Number of ways to choose 6 students out of 14= [tex]^{14}C_6[/tex]  [Using combinations]

Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) = [tex]^{9}C_4\times\ ^{5}C_2[/tex]

If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-

[tex]\dfrac{^{9}C_4\times \ ^{5}C_2}{^{14}C_6}[/tex]

[tex]=\dfrac{\dfrac{9!}{4!5!}\times\dfrac{5!}{2!3!}}{\dfrac{14!}{6!8!}}\\\\=\dfrac{1260}{3003}\\\\=\dfrac{60}{143}[/tex]

hence, the required probability = [tex]\dfrac{60}{143}[/tex] .

Answer:

C. Seasonal variation

Step-by-step explanation:

Distinct pattern around a trend line can be caused by seasonal variation.

Seasonal variation refers to a component of a time series which can be defined as the repetitive and predictable movement around the trend line in a year or less. It is caused by temperature, rainfall, public holiday and cycles of season

Seasonal variation can be detected by measuring the quantity of interest for small time intervals, such as days, weeks, months or quarters.

Firms affected by seasonal variation are usually interested in knowing their performance relative to the normal seasonal variation. They need to identify and measure this seasonality so as to help with planning.

Answer:

A). A(t) = P(1+r/n)^(nt)

B). DA/Dt = np(1+r/n)^(t)

C). A(5) =$ 5664.0

D).t = approximately 13.5 years

Step-by-step explanation:

A(t) = P(1+r/n)^(nt)

P = $5000

n= t

r= 2.5%

After five years t = 5

A(t) = P(1+r/n)^(nt)

A(5) = 5000(1+0.025/5)^(5*5)

A(5) = 5000(1+0.005)^(25)

A(5)= 5000(1.005)^(25)

A(5) = 5000(1.132795575)

A(5) = 5663.977875

A(5) =$ 5664.0

When the balance A= $7000

A(t) = P(1+r/n)^(nt)

7000= 5000(1+0.025/n)^(nt)

But n= t

7000= 5000(1+0.025/t)^(t²)

7000/5000= (1+0.025/t)^(t²)

1.4= (1+0.025/t)^(t²)

Using trial and error

t = approximately 13.5 years

Answer:

  SAS Postulate

Step-by-step explanation:

The contributors to the proof are listed in the left column. They consist of a congruent Side, a congruent Angle, and a congruent Side. The SAS Postulate is an appropriate choice.

Answer:

The correct answers are:

1. No, because it does not lead the respondent to any particular answer (D)

2. The original question is not biased (D)

Step-by-step explanation:

In developing survey questions, response biases are tendencies for respondents to respond inaccurately or falsely to a particular question and this largely has to do with the way the questions are framed. Biased questions build preconceived thoughts in the mind of the respondent, increasing the tendency for them to lean towards a particular answer.

In this example, the question "How often do you eat fruit during an average week?" is not biased because it does not suggest to the respondent whether eating fruits is good or bad, it just directs the respondent to a particular number, hence the question is not biased.

Answer:

[tex]\angle AE = 32^{\circ}[/tex]

[tex]\angle EAD = 212^{\circ}[/tex]

[tex]\angle BE = 133^{\circ}[/tex]

[tex]\angle BCE = 227^{\circ}[/tex]

[tex]\angle AED = 180^{\circ}[/tex]

[tex]\angle BD = 79^{\circ}[/tex]

Step-by-step explanation:

The central angle of a circle is equal to 360º, whose formula in this case is:

[tex]\angle AB + \angle BC + \angle CD + \angle DE + \angle EA = 360^{\circ}[/tex]

In addition, the following conditions are known from figure:

[tex]\angle BC = 47^{\circ}[/tex], [tex]\angle DE = 148^{\circ}[/tex]

[tex]\angle DE + \angle EA = 180^{\circ}[/tex]

[tex]\angle CD + \angle DE = 180^{\circ}[/tex]

[tex]\angle AB + \angle BC + \angle CD = 180^{\circ}[/tex]

Now, the system of equations is now solved:

[tex]\angle EA = 180^{\circ}-\angle DE[/tex]

[tex]\angle EA = 180^{\circ}-148^{\circ}[/tex]

[tex]\angle EA = 32^{\circ}[/tex]

[tex]\angle CD = 180^{\circ}-\angle DE[/tex]

[tex]\angle CD = 180^{\circ}-148^{\circ}[/tex]

[tex]\angle CD = 32^{\circ}[/tex]

[tex]\angle AB = 180^{\circ} - \angle BC - \angle CD[/tex]

[tex]\angle AB = 180^{\circ}-47^{\circ}-32^{\circ}[/tex]

[tex]\angle AB = 101^{\circ}[/tex]

The answers are described herein:

[tex]\angle AE = 32^{\circ}[/tex]

[tex]\angle EAD = 212^{\circ}[/tex]

[tex]\angle BE = 133^{\circ}[/tex]

[tex]\angle BCE = 227^{\circ}[/tex]

[tex]\angle AED = 180^{\circ}[/tex]
