If the average rate of travel is 100 miles per day, about how long would it take to
travel down each river in days?

Answers

Answer:

Distance, rate and time problems are a standard application of linear equations. When solving these problems, use the relationship rate (speed or velocity) times time equals distance.

  

Explanation:

For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h)(4h) = 120 km.

The problems to be solved here will have a few more steps than described above. So to keep the information in the problem organized,  use a table. An example of the basic structure of the table is below:

b. How much would a 50-word classified ad cost?

Answers

A. A 25-word classified ad would cost $17.50
Explanation: 0.55 x 10 = 5.5. 5.5 + 12 = 17.5

B. A 50-word classified ad would cost $31.25
Explanation: 0.55 x 35 = 19.25. 19.25 + 12 = 31.25

Researchers want to determine whether all frozen pizzas have the same proportion of toppings regardless of the brand of pizza. To test this, they sampled randomly pizzas of each brand and recorded their findings in the table.
Brand Topping
Pepperoni Sausage Onion Mushrooms
Digiorno 14 21 17 17
Tombstone 11 8 10 6
Red Baron® 17 13 14 11
Tony's 9 17 15 18
Part A: What are the correct degrees of freedom for this table? (2 points)

Part B: Calculate the expected count for the number of pepperoni for Red Baron® pizza. Show your work.

Part C: Is there sufficient evidence that there is a difference in the proportion of toppings for the different brands of pizza? Provide a statistical justification for your conclusion.

Answers

The degree of freedom is 9 and expected amount for the number of pepperoni for Red Baron is 12.867.

How to calculate the degree of freedom?

The degree of freedom will be calculated thus:

= (Number of rows - 1) × (Number of columns - 1)

= (4 - 1)(4 - 1)

= 3 × 3 = 9

The expected amount for the number of pepperoni for Red Baron will be:

= (55 × 51) / 218

= 12.867

Also, the p value is 0.6023 and this indicates that there is no sufficient evidence that there is a difference in the proportion of toppings for the different brands of pizza since p value is greater than 0.05.

[tex]\frac{4}{5} *\frac{4}{4} +\frac{3}{4}*\frac{5}{5} = \frac{16}{20} +\frac{15}{20} = \frac{31}{20}[/tex]

A. $12.60
B. $45.60

It would be 12.60 as the profit, while the revenue is 54.60

Therefore, the answer would be

42*.3=

12.6

12.6+42=

54.60

Since it is asking for what the price will be after it is marked up you have to find the marked up price so you take $42 x 0.3 which is $12.60 then you add that to the $42 which is $54.60 which is C

Let x = the amount of money Jane had before she took out any

Set up the equation

x - 135 = 650

To solve the equation, we must add 135 on both sides to cancel the -135 on the left side of the equal sign.

x - 135 = 650

x = 785

Which is the equation of a line that has a slope of -5 and a y-intercept of -3? Show me how you arrived at your answer.
a) 2y = -5x - 3
b) -2y = 10x - 6
c) -2y = 10x + 6
d) 2y = 10x - 6 ​

Answers

Answer:

c) -2y = 10x + 6

Step-by-step explanation:

The equation of a line in slope-intercept form is:

[tex]y=mx+b[/tex]

The variables stand for:

[tex]y:$ y-coordinate of any point on the line\\$x:$ x-coordinate of any point on the lien\\$m: $ Slope of the line\\$b: $ y-intercept of the line; where the line meets the y-axis[/tex]

Plugging in the given information into the equation:

[tex]y=-5x+(-3)\\y=-5x-3[/tex]

Go through the answer choices:

a)  2y = -5x - 3

Divide both sides of the equation by 2

[tex]y=-\frac{5}{2}x-\frac{3}{2}\rightarrow\text{Incorrect!}[/tex]

b) -2y = 10x - 6

Divide both sides of the equation by -2

[tex]y=\frac{10}{-2}x-\frac{6}{-2}\\y=-5x-(-3)\\y=-5x+3\rightarrow\text{Incorrect!}[/tex]

c) -2y = 10x + 6

Divide both sides of the equation by -2

[tex]y=\frac{10}{-2}x+\frac{6}{-2}\\y=-5x+(-3)\\y=-5x-3\rightarrow\text{Correct!}[/tex]

d) 2y = 10x - 6

Divide both sides of the equation by 2

[tex]y=\frac{10}{2}x-\frac{6}{2}\\y=5x-3\rightarrow\text{Incorrect!}[/tex]

Therefore the answer is c) -2y = 10x + 6

Additional Comments:

We can only divide both sides of the equation by 2 and/or -2 because of the Division Property of Equality. This property states that if we divide one side of the equation by a certain quantity, we must divide the other side by the same quantity so that the equation remains equal.

Step-by-step explanation:

Question 1

Perimeter of a rectangle = 2W + 2L

(where W is the width and L is the length)

Given:

width = 2a + 3length = 8a - 12

Perimeter = 2(2a + 3) + 2(8a - 12)

                 = 4a + 6 + 16a - 24

                 = 20a - 18

Question 2

When a = 3

⇒ perimeter = 20(3) -18

                     = 60 - 18

                     = 42 centimeters

Question 3

The dashes on the side lengths mean those sides are equal in length.

⇒ perimeter = (7b - 2) + (7b - 2) + (3b + 7)

                     = 17b + 3

Question 4

When b = 6

⇒ perimeter = 17(6) + 3

                     = 102 + 3

                     = 105 meters
