Stock Yield = [tex]\frac{Annual Dividend}{Current Stock Price}[/tex]

Step-by-step explanation:

Stock yield is found by the annual dividend divided by the current stock price.

There is an inverse relationship between the stock yield and the current  stock price.

For example, let's assume we have some shares of Company ABC, which pays $1.20 per share in annual dividends and the current stock price is $12.00, then by using the formula above we can calculate the stock yield of the Company ABC as,

Stock Yield  of company ABC = [tex]\frac{Annual Dividend}{Current Stock Price}[/tex]

                                                  = [tex]\frac{\$1.20}{\$12.00}[/tex]

                                                   = 0.1

                                                  = 10%

Step-by-step explanation:

You can only make one because once an angle is given, the only possibility is to connect the two sides. You can't change it to an obtuse triangle with that.

Everyone else will be a congruent to the first one triangle.

SAS stands for "side, angle, side" and means that we have two congruent triangles where we know two sides and the included angle are equal.

The bolt with a diameter of 0.52 inch has a percent error of approximately 5.45% from the advertised 0.55 inch, which is within the acceptable margin of less than 6%. Therefore, it should be included in the package.

The question revolves around determining if a bolt with a diameter of 0.52 inch should be packaged given that the labeled diameter is 0.55 inch and the allowable percent error is less than 6%. To calculate the percent error, we use the formula: Percent Error = (|Actual Value - Theoretical Value| / Theoretical Value) × 100%. Applying the numbers: Percent Error = (|0.52 - 0.55| / 0.55) × 100% = (0.03 / 0.55) × 100% ≈ 5.45%.

Since the percent error of 5.45% is less than 6%, the bolt with a diameter of 0.52 inch should be included in the package. This decision is based on the calculated percent error being within the accepted tolerance level.

Answer:

The height of the fox in Huseyin's drawing is, 16 units

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the statement: Huseyin draws a fox with a scale of 3 units on his graph paper represents 15 cm. The fox has an actual height of 80 cm.

⇒ We are given Scale of 3 units.

On graph paper the length of fox is 15 cm.

The fox has an actual height = 80 cm

let x be the height in units of the fox in Huseyin's drawing.

By definition of proportion;

[tex]\frac{3}{15} = \frac{x}{80}[/tex]

by cross multiply we get;

[tex]3 \times 80 = 15x[/tex]

Simplify:

240 = 15x

Divide both sides by 15 we get;

x = 16 units.

Therefore, the height of the fox in Huseyin's drawing is, 16 units

Answer:

16 units

(1 & 2/3) ft = (1 ft) + (2/3 ft)

(1 & 2/3) ft = 12 inches + 12*(2/3) inches

(1 & 2/3) ft = 12 inches + 8 inches

(1 & 2/3) ft = 20 inches

If the tree grows 5 inches per year, then it will take 4 years to get to 20 inches since 5*4 = 20. You can also divide to get 20/5 = 4.

So it takes 4 years for the tree to grow 1&2/3 feet tall.

Answer:

4 years

Step-by-step explanation:

Okay, so basically write a proportion

5 inches/per year

Then, find out how many inches are in  1 2/3 feet

1 2/3 = 1 8/12

Meaning there 1 2/3 feet is 1 foot and 8 inches. We know a foot is 12 inches. so then you just add 12 + 8 which is 20

Now going back to your proportion

5 inches/ per year =20 inches/x years

We know 5 goes into 20 4 times. Meaning to get to 20, your'e going to have to multiply the numerator by 4. But whatever you do to the numerator, you must do to the denominator. So multiply 1 x 4 which is 4 meaning it is going to take 4 years for the tree to grow 1 2/3 feet.

Point-Slope form:  [tex]y+1=-\frac{6}{15}(x+5)\\[/tex]

standard form:  [tex]2x+5y=-15[/tex]

Step-by-step explanation:

The standard form is given by: [tex]Ax+By=C[/tex]

The point-slope form is given by: [tex]y-y_1=m(x-x_1)[/tex]

point [tex](10,-7)[/tex] as point [tex](x_2,y_2)[/tex]

Let's find the slope:

[tex]m=\frac{-7-(-1)}{10-(-5)}=-\frac{6}{15}[/tex]

1. So, point slope form can be written as:

[tex]y-(-1)=-\frac{6}{15}(x-(-5))\\y+1=-\frac{6}{15}(x+5)\\[/tex]

2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:

[tex]y+1=-\frac{6}{15}x-2\\y+\frac{6}{15}x=-2-1\\y+\frac{6}{15}x=-3[/tex]

But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:

[tex]y+\frac{6}{15}x=-3\\15y+6x=-45[/tex]

We can factor out a 3, so it becomes:

[tex]15y+6x=-45\\5y+2x=-15[/tex]

So standard form is [tex]2x+5y=-15[/tex]

Answer:

B. The total price depends on the number of crates

Step-by-step explanation:

We can immediately rule out C & A because the two factors in the graph are crates and total price. So both the number of crates and total price will be part of our answer, but pumpkins aren't shown on the graph at all.  

This leaves us with B & D. Using common sense we know that the number of crates isn't going to change if the total cost changes but rather the total cost will change depending on how many crates you buy.

Final answer:

To accommodate 15 people, the elevator must be approximately 4.7 feet wide.

Explanation:

The question is asking us to calculate the width of the elevator box that can legally accommodate 15 people, given that the elevator building code requires at least 2.2 square feet per person and the depth of the elevator is 7 feet.

First, we need to find out the total area required for 15 people:

Total area = Number of people × Area per person = 15 × 2.2 square feet

Total area = 33 square feet

As we have the depth of the elevator, we can now calculate the width:

Total area = Width × Depth

Width = Total area / Depth

Width = 33 sq ft / 7 ft

Width ≈ 4.7 feet

Therefore, the elevator must be approximately 4.7 feet wide to accommodate 15 people as per the building code's requirements.

By using the properties of angle bisectors and congruent triangles, we can demonstrate that ABCD has both pairs of opposite sides parallel, proving it is a parallelogram.

Proof that ABCD is a Parallelogram

To prove that quadrilateral ABCD is a parallelogram:

DE bisects AC, meaning D is the midpoint of AC, and E is the midpoint of BD.

Since <1 is congruent to <2, triangles ADE and CDE are congruent by the Angle-Side-Angle (ASA) criterion.

If these triangles are congruent, then AD = DC and AE = EC by corresponding parts of congruent triangles (CPCTC).

Since DE bisects AC and BD, triangles ADE and CDE are mirror images.

Consequently, AD is parallel to BC, and AB is parallel to CD.

Because opposite sides are congruent and parallel, we conclude that ABCD is a parallelogram.

Answer:

6(4a+3b-5)

Step-by-step explanation:

They all share a common factor of 6 so we can factor out the six, 6(4a+3b-5)

Answer:

2a+b=5/2

Step-by-step explanation:

given the expression

24a + 12b - 30

Step one :

To solve this we need to look for a common factor

Here 6 is a common factor

So divide all through by 6

24a/6+12b/6-30/6

4a+2b-5

4a+2b=5

Step two :

We can still factor 2 out for the terms with variables

2(2a+b)=5

2a+b=5/2

Answer:

The median of the histogram is scores ranging from 70-80

Step-by-step explanation:

Median of a histogram is always the "class interval" in which the MIDDLE NUMBER falls in.

If we add up all the bars (y-axis), we see HOW MANY NUMBERS in total there are. So we have:

[tex]1+2+1+2+6+9+13+5=39[/tex] numbers in total

What is the middle number out of 39 numbers?

It is: [tex]\frac{n+1}{2}[/tex] th number where [tex]n=39[/tex] for this problem

So, the middle number is : [tex]\frac{39+1}{2}=\frac{40}{2}=20[/tex]th number

Which class interval does the 20th number fall into?

So, definitely, 20th number falls into the sixth class interval which is "70-80".

Hence, the median of the histogram is scores ranging from 70-80.

Answer:

(x-3, y+4) hope this helps.

Answer:

The correct answer option is (x + 3, y - 4).

Step-by-step explanation:

If we are talking about the translation rule with respect to the origin (0, 0), then the correct option will be (x + 3, y - 4).

Since moving to the right on the x axis means a positive addition so moving three units right will mean 'plus 3'.

While moving down means that the value of y is going in negative so it will be (y - 4)

Answer:

a. opens: upward

b. a.o.s.: x = 1

c. vertex: (1, -4)

d. x-intercepts: (-1, 0), (3, 0); y-intercept: (0, -3)

Step-by-step explanation:

By looking at the graph, we can see that the parabola opens upward. This means that its a-value is positive.

The axis of symmetry is the line that passes exactly through the center of the parabola. It always starts with x = __, because it is a vertical line.

The center of this parabola is at the x-value of 1, so we can say that the equation of the axis of symmetry is x = 1.

The vertex is at the highest or lowest point of the parabola, also known as the maximum or minimum point. Since this graph opens up, the vertex is at the minimum point.

Look at the graph and find the point where the parabola opens upwards. This point is at the x-value of 1 and the y-value of -4, so the vertex of the parabola is at (1, -4).

Again, look at the graph provided to find the x and y-intercepts. On the x-axis, the parabola crosses through at the x-values of -1 and 3, so the x-intercepts are (-1, 0) and (3, 0).

The parabola crosses the y-axis at the y-value of -3, so the y-intercept of the parabola is (0, -3).

Answer:

The average U.S. citizen throws away about 133.8 pounds of garbage a month.

Step-by-step explanation:

First take the total amount of trash thrown away in a year (1,606), and divide it by the number of months in a year (12).

1,606 / 12 = 133.833333

You would get 133.833333 and would round it to the nearest tenth and get 133.8.

Answer:

133.83 lb/month, or  133.8 lb/month to the nearest tenth.

Step-by-step explanation:

Here we need to find the unit rate of throwing stuff away.

To do this, divide 1,606 lb by 12 months, since we want the answer in pounds per month:

1,606 lb

------------- = 133.83 lb/month, or 133 5/6 lb/month

Check out the attached image below. It shows the bar graphs of each school. As you can see in figure 2 (Cleveland highschool), the data is more spread out compared figure 1. So this has a higher standard deviation. The standard deviation measures spread. The larger the standard deviation is, the more spread out the values will be. It can be thought of as a measure of how distant each value is from the mean.

Lucio spent a total of $5.37 on candy by purchasing 1.7 pounds of gummy bears at $1.88 per pound and 0.8 pounds of caramels at $2.72 per pound, and then summing both costs.

To calculate the total cost of candy that Lucio is buying, we compute the cost of each candy type separately and then add those costs together. He buys 1.7 pounds of gummy bears at $1.88 per pound and 0.8 pounds of caramels at $2.72 per pound.

For the gummy bears: 1.7 pounds × $1.88 per pound = $3.196

For the caramels: 0.8 pounds × $2.72 per pound = $2.176

To find the total cost, we add the cost of gummy bears and caramels. Therefore, the total cost is $3.196 + $2.176 = $5.372. After rounding to two decimal places, we conclude that Lucio spent a total of $5.37 on candy.

A) each donut costs $0.65

B) the price for 1 and 1/2 dozen of donuts (18 donuts) is $11.70

Step-by-step explanation:

For a you have to divide $7.80 by 12 (since its a dozen) and thats how you get $0.65

For b you have to multiply the price of each donut ($0.65) by the 1 and 1/2 dozen (18 donuts) and thats how you get $11.70

A) The price per donut is approximately $0.65, and B) the cost of 1 and 1/2  dozen donuts is $11.70.

Certainly, let's break it down:

A) To find the price per donut, divide the total cost by the number of donuts in a dozen:

  Price per donut = $7.80 / 12 ≈ $0.65

B) Calculate the cost of 1 dozen:

  Cost of 1 dozen = $7.80

  Now, for [tex]\( \frac{1}{2} \)[/tex] dozen, multiply the price per donut by 6 (half of 12):

  Cost of [tex]\( \frac{1}{2} \)[/tex] dozen = $0.65 × 6 = $3.90

  Add the cost of [tex]\( \frac{1}{2} \)[/tex] dozen to the cost of 1 dozen:

  Total cost for 1 and [tex]\( \frac{1}{2} \)[/tex] dozen = $7.80 + $3.90 = $11.70

In summary, A) the price per donut is approximately $0.65, and B) the cost of 1 and [tex]\( \frac{1}{2} \)[/tex] dozen donuts is $11.70.
