A rectangle's length is 7 less than 3 times it's width. If the perimeter of the rectangle is 170 inches, what is the width, length and area of the rectangle?

Answer:

18$

Step-by-step explanation:

Answer:

A) 0.00686

B) 0.01673

C) 0.99587

Step-by-step explanation:

For this question, we are interested in the first success and we will Thus make use of geometric probability distribution.

It goes by the formula;

P(x) = [(1 - p)^(x - 1)]p

We are told that One out of every 119 tax returns that a tax auditor examines requires an audit.

Thus; p = 1/119 = 0.0084

A) Probability that the first return requiring an audit is the 25th return the tax auditor examines is given by;

P(25) = [(1 - 0.0084)^(25 - 1)]0.0084

P(25) = 0.00686

B) Probability the first requiring an audit is the first or second return the tax auditor examines, is;

P(1 or 2) = P(1) + P(2)

P(1) = [(1 - 0.0084)^(1 - 1)]0.0084

P(1) = 0.0084

P(2) = [(1 - 0.0084)^(2 - 1)]0.0084

P(2) = 0.00833

Thus;

P(1 or 2) = 0.0084 + 0.00833

P(1 or 2) = 0.01673

C) Probability that none of the first five returns the tax auditor examines require an audit is given by;

P(X > 5) = 1 - P(X ≤ 5)

Now,

P(X ≤ 5) is expressed as;

P(X ≤ 5) = P(1) + P(2) + P(3) + P(4) + P(5)

We know P(1) & P(2) already. Let's find P(3), P(4) and P(5)

P(3) = [(1 - 0.0084)^(3 - 1)]0.0084

P(3) = 0.00826

P(4) = [(1 - 0.0084)^(4 - 1)]0.0084

P(4) = 0.00819

P(5) = [(1 - 0.0084)^(5 - 1)]0.0084

P(5) = 0.00812

P(X ≤ 5) = 0.0084 + 0.00833 + 0.00826 + 0.00819 + 0.00812

P(X ≤ 5) = 0.00413

P(X > 5) = 1 - 0.00413

P(X > 5) = 0.99587

Answer:

54

Step-by-step explanation:

Well, divide 300 by 100, which gets you 3. So 3 feet of book shelves = 1%

So 3x18=54

Answer:

R: (Y| E R {-4<=y<=-1})

Step-by-step explanation:

Just look at where the graph is limited to vertically, in this case -1 and -4.

The range of the given graph is [-4,-1] and this can be determined by observing the given graph.

The following steps can be used in order to determine the range of the given graph:

Step 1 - The range is the different values of 'y' at different values of 'x'.

Step 2 - According to the given graph, the maximum value of 'y' is -1.

Step 3 - According to the given graph, the minimum value of 'y' is -4.

Step 4 - So, the range of the given graph is given below:

The expected profit on the listing is $2377.14

Step-by-step explanation:

Given that:

The probability of selling the house in 6 months is p = 0.33

The probability of not selling the house = 1 - 0.33 = 0.67

Suppose X represents the profit on the listing;

Then: we can compute the expected profit on the listing as:

E(X) = ($19166 × 0.33) - ($5892 × 0.67)

E(X) = $6324.78 - $3947.64

E(X) = $2377.14

Thus, the expected profit on the listing is $2377.14

Answer:

2. B. The rate of change is 2

3. C. The rate of change is 2 inches per hour

4. B. The rate of change is 1.25 degrees Fahrenheit per day

5. (-0.5, 3) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x = 0

Step-by-step explanation:

2. Using the points (-1, -1) and the (1, 3) we have;

The rate of change = (Change in the y-values)/(Corresponding change in the x-values)

The rate of change = (3 - (-1))/(1 - (-1)) = 4/2 = 2

The rate of change is 2

3. Using the points (0, 0) and the (5, 10) we have;

The rate of change = (Change in the y-values)/(Corresponding change in the x-values)

Given that the function is a linear function, the rate of change of the function at 3 hours is given by the slope, m, as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where;

(x₁, y₁) = (0, 0)

(x₂, y₂) = (5, 10)

The y-coordinate being the inches of snow, and the x-coordinate being the time in hours, we have;

The rate of change = (10 - 0)/(5 - 0) = 10/5 = 2

The rate of change is 2 inches per hour

4. Given that the function is a linear function, the rate of change of the function at ninth day is given by the slope, m, as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where;

(x₁, y₁) = (2, 55)

(x₂, y₂) = (10, 65)

The y-coordinate being the temperature in degrees, and the x-coordinate being the time in days, we have;

[tex]Slope, \, m =\dfrac{65-55}{10-2} = \dfrac{10}{8} = 1.25[/tex]

The rate of change is 1.25 degrees Fahrenheit per day

5. The points on the graph of the function that come before and after the point where the graph of the function crosses y-axis (the y-intercept) and are close to point are (-0.5, 2) and (0.5, 3)

Therefore, (-0.5, 2) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x = 0.

Answer:

p1: y-100=1.6(x-25)

p2 y=1.6x+60

p3 slope; 1.60

p4 y intercept, slope intercept form, easier to fine using slope intercept

Step-by-step explanation:

this was for savvas 2.2 practice

The required point slope of the equation is y-100=1.6(x-25) and the slope-intercept equation y = 1.6x + 60 and the slope represents the cost per invitation.

Given that,  
The total price of a printing job at Incredible Invites includes the cost per invitation plus a one-time set-up fee. Write equations in point-slope and slope-intercept forms to model the situation. What part of the equations represents the cost per invitation is to be determined.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
Let the number of invitations be x, and the total cost be y.
Slope-point form of the equation is given by,
(y - y₁) = (y₂ - y₁)/ (x₂ - x₁ ) (x - x₁)
substitute value in the equation,
y - 100 = (140 - 100)/ (50 - 25)(x - 25)
y - 100 = 40 / 25 (x - 25)
y - 100 = 1.6 (x - 25)  - - - - - - (point-slope form)
y = 1.6x - 25 * 1.6 + 100
y = 1.6x - 40 + 100
y = 1.6x + 60 - - - - - (slope-intercept form)
Slope = 1.6

Thus, the required point slope of the equation is y-100=1.6(x-25), and the slope-intercept equation y = 1.6x + 60, and the slope represents the cost per invitation.

Answer:

Number 14 is a function and Number 16 is NOT a function.

Step-by-step explanation:

To check if a set of numbers form a function, you can look at the x values or the imput values.

For number 14 the x values are : 4,-3,-4,5,6. When looking at these values, there can only be one of each number.

For example in number 16, there's two 0's and we cannot allow that! So therefore, number 16 is not a function.

Also note, the y values are called the outputs.

A function is only allowed to have ONE imput with each output.

Answer:

a = 3h + 2.50b

Step-by-step explanation:

Greg picks apples to make money over the summer. He earns $3 an hour plus $2.50 for each bushel he picks. Write a formula that will help Greg determine how much money he will earn in one week.

Let

a = Total amount earned

h = Hours worked in one week

b = Number of bushels picked

Solution:

Amount earned per hour = $3

Amount earned per bushel picked = $2.50

Total amount earned = (Amount earned per hour) ( Hours worked in one week) + (Amount earned per bushel picked) (Number of bushels picked)

a = 3*h + 2.50*b

= 3h + 2.50b

a = 3h + 2.50b
