Answer: 5/12

Step-by-step explanation:

6x6=36

36 is all possible values.

1+2+3+4+5=15

The higher the number betty rolls there will be one less possible value that will be bigger than hers.

15/36=5/12

Answer:

[tex]19\%[/tex]

Percentages are evaluated values that say how much of a whole is occupied by that value. For example, if we were to say 75% of a strawberry pie remained, we could also see this as 3/4, or three-fourths.

To solve this particular problem, we will need to divide two values and convert a decimal to a percentage.

First, set up the fraction of economics majors that are freshman students to the total number of freshman students.

[tex]\displaystyle \frac{1634}{8600}[/tex]

Then, divide the two using a calculator or long division.

[tex]\displaystyle \frac{19}{100}[/tex]

Finally, to convert this to a decimal, use a calculator.

[tex]0.19[/tex]

To convert a decimal to a percentage, multiply the decimal by 100.

[tex]0.19 \times 100 = 19\%[/tex]

The final answer is [tex]19\%[/tex].

Answer:

19%

Key Points:

In order to find the percentage of freshman majoring in economics, we must divide the econ major students by the overall size of the freshman class.

[tex]\frac{1634}{8600}[/tex]

Our next step is to grab a calculator and input 1634 ÷ 8600. You can alternatively use the long division method but a calculator would work best. After calculating, your answer should come out to be 0.19

Now, you need to multiply it by 100 so that you can create a percentage.

0.19 × 100 = 19%

Therefore, 19% of the freshman class are economics majors.

The coordinates of endpoint B are (-7, 11)

From the question, we are to determine the coordinates of the endpoint B

If the coordinates of the endpoints of a line, AB, are A(x₁, y₁) and B(x₂, y₂), then the coordinates of the midpoint is given by

((x₁+x₂)/2, (y₁+y₂)/2)

From the given information,

The coordinates of A are (3, 7) and the coordinates of the midpoint are (-2, 9)

Let the coordinates of endpoint B be (x, y)

Then,

(3+x)/2 = -2

3 +x =-4

x = -4 -3

x =  -7

and

(7 + y)/2 = 9

The decay factor for the annual rate of change of -0.1 % is 0.999.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = - 0.1 % = - 0.1 / 100 = - 0.001

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (- 0.001)

B = 1 - 0.001

B = 0.999

Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.999.

Answer:

y=x+6

Step-by-step explanation:

The gradient of the line is change in y/ change in x

Thus meaning the gradient is 1. (defined as x)

The line crosses through the y-axis on the point (0,6)

So your euqation will be y = (1 - the gradient) x + (interception of y-axis) 6

Answer:

y = x + 6

Step-by-step explanation:

The general form of an equation of a line is

y= mx+b

y = slope ·x + y-intercept

Find the slope of the line, m:

-Pick any 2 points on the line, for example lets pick the points (0, 6) and (3, 10)

-Start at any of the points and go towards the other while note the path

start at (0, 6) and to go to (4, 10) we have to

go up (rise) 4 units  from 6 to 10 and

go to the right (run) 4 from 0 to 4.

Slope = m = rise/run = 4/4 = 1

m = 1

Find the y-intercept, b:

The y-intercept is where the line intersects the y-axis. By looking at the given graph we can see y-intercept is 6.

b = 6

The equation of our line is

y = x + 6

Answer:

the answer to that question is 3

Answer: (Looking back, I may have gotten this question wrong, but if I haven't then nice.)

a) 13 degrees

b) acute angle

Step-by-step explanation:

Given that we know a triangle is 180 degrees. Lets recall what an obtuse, acute, right and reflex angle are.

Obtuse: An angle greater than 90 degrees

Acute: An angle less than 90 degrees

Right: An angle that is 90 degrees

Reflex: An angle in between 180-360 degrees

Since we know that two of the three angles are 54 and 113 degrees, we can say that 54+113+x=180. That means that the missing angle, x, is 13 degrees.

Knowing that 13 is less than 90, we can also say that the third angle is an acute angle.

What is Division method?

Division method is used to distributing a group of things into equal parts.

1. Carla Sanborn was born on July 12, 1936.

On October 25, 1977, She bought $30,000 worth of ordinary  life insurance on August 25, 2020.

Now, firstly we have to find her age for insurance purpose and secondly her annual premium.

Since, The age for her insurance purposes will be calculated by the nearest birthday year.

So,

July 12 ,1989 - October 25, 2020 = 31 years.

Hence, She is 31 years of age.

Now, For Her annual premium we divide what she purchased with her age as,

$30,000/31 = $ 967.74

Which is approximately be $968.

2. Bruce Lovegren was born on September 27, 1950.

On April 27, 1977, he purchased a $15,000 ten-year term life insurance     policy.

Now, firstly we have to find her age for insurance purpose and secondly her annual premium.

Since, The age for her insurance purposes will be calculated by the nearest birthday year.

So, September 27, 1950 - April 27, 1977 = 27 years

Now, For Her annual premium we divide what she purchased with her age as,

$15,000/ 27 = $555.55

Which is approximately be $556.

3. Edward Anderson has $30,000 of twenty-payment life.

He is twenty-six years old.

For His annual premium we divide what he purchased with his age as,

$30,000/ 26 = 1,153.84

Which is approximately be $1,154

Hence, His semiannually premiums = $1,154/2 = $577

And, His quarterly premiums =  $1,154/4 = $288.5

And, His monthly premiums = $1,154/12 = $96

4. Tom Harris is twenty-four.

He purchases $15,000 of ten-year term insurance.

For His annual premium we divide what he purchased with his age as,

$15,000/ 24 = $625

His semiannually premiums = $625/2 = $312.5

His quarterly premiums = $625/4 = $156.25

His monthly premiums = $625/12 = $52

5.  Emily Webster purchased a twenty-year endowment policy at age 27 with a face value of $25,000.

His semiannually premiums =  $926/2 = $463

The difference between these payment options = $926 - $463 = $463

6. Tom Hornet purchases $7,000 of ten year term life. He is 31 years old.

For His annual premium we divide what he purchased with his age as,

$7,000/31 = $225.8

The trench will require 9168 cubic feet of dirt to be removed.

Here, we are given that a homeowner is digging a 3 -ft-deep trench around the perimeter of his property.

Length of the property = 210 feet

Breadth of the property = 180 feet

Let us now consider one side of the 180-foot-long trench.

There are two such trenches, each with a width of 4 feet and a height of 3 feet.

Thus the volume of the trench = 2(length × breadth × height)

Volume = 180 × 4 × 3 × 2

= 4320 cubic feet

Now we are left with two other sides of the trench with the following dimensions-

Height = 3ft

Breadth = 4ft

Length = 210 - 8 = 202ft

Thus, volume = 202 × 4 × 3 × 2

= 4848 cubic feet

Thus, the total volume of the trench = 4848 + 4320 = 9168 cubic feet.
