Answer:

25 Chapters

Step-by-step explanation:

We are given:

Number of Chapters read = 14

Percentage of Book finished = 56%

Number of Chapters in the Book:

Since 56% of 'x' chapters is 14:

[tex]x*\frac{56}{100}[/tex] = 14

[tex]x = \frac{14 * 100}{56}[/tex]                             [multiplying both sides by 100/56]

[tex]x = \frac{100}{4}[/tex]                                  [since 14*4 = 56]

x = 25

Therefore, the book has 25 chapters

Answer:

The book has a total of 25 chapters.

Step-by-step explanation:

If 14 is 56% of the book, we can set up a proportion that can find the total number of chapters in the book.

A proportion looks like:

Our first fraction will be the two values we are given: 14 chapters and 56% of the book.

Then, our second fraction will contain an unknown variable. We would need to complete this many chapters to complete the book, so 100% of the book would be read once a certain number of chapters are reached. Therefore, we don't know how many chapters are needed to complete the book, so this is our unknown variable. We can define this as x.

Therefore, our second fraction is:

Now, we can set these fractions equal to each other.

Then, we can cross multiply our fractions to create an equation. Following our sample proportion, we would get:

So, we can follow the same policy with our proportion.

[tex]\displaystyle (14)(100) = (56)(x)\\\\1400 = 56x\\\\56x = 1400\\\\\frac{56x}{56} = \frac{1400}{56}\\\\x = 25[/tex]

Therefore, 56% of the book is 14 chapters. With this information, we have determined that 100% of the book is 25 chapters.

Answer:

y-intercept: -5

Slope: 4

Equation: y = 4x - 5

Step-by-step explanation:

✔️The y-intercept is the value of y when x = 0. From the table of values, it shows that when x = 0, y = -5. Therefore:

y-intercept (b) = -5

✔️using two pairs from the table, (1, -1) and (2, 3):

[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 -(-1)}{2 - 1} = \frac{4}{1} = 4 [/tex]

Slope = 4

✔️To write an equation for the function, substitute m = 4, and b = -5 into y = mx + b.

Thus:

y = 4x +(-5)

y = 4x - 5

Answer:

1pound of granola= $3.25

g pound of granola=g*3.25

=3.25g$

1 pound of flour = 0.74$

f pound of flour = f*0.74

= 0.74f$

The expression to determine the total cost of buying the above items= (3.25g+0.74f)

Step-by-step explanation:

First, you can find angle 1 by using the triangle angle formula, stating that all angles add up to 180 deg. Thus, angle 1 is equal to 180-72-57= 51 deg.

Next, you can find angle 2 by using the right angle shown. This means that angle 2 plus 72 deg = 90 deg. Thus, angle 2 is equal to 90-72= 18 deg.

For angle 3, notice that it is bordering the other angle on a straight line. A straight line is equal to 180 deg. This means that angle 3 + 57 deg = 180 deg. Thus, angle 3 is equal to 180-57= 123 deg.

Angle 4 can be found by using the triangle angle formula used for angle 1. In this case, angle 2+3+4 will equal 180 deg. Thus, angle 4 is equal to 180-18-123= 29 deg.

Answer:

1= 51

2= 18

3= 123

4= 39

Step-by-step explanation:

First you must know that all triangles equal 180. From there you can add and subtract the known numbers to get your answers. For example with angle 1, because you are give 72 and 57 you must add them together to get 129 then subtract that from 180 to get 51. You can do similar steps for all the angles to receive the answers.

Answer:

Remove the variable from the Model

Step-by-step explanation:

Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.

Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.

So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

Answer:

15/20 cups of cranberry juice

Step-by-step explanation:

3/5 cranberry juice makes 12

12/2=6

3/5= 0.3

6/2=3

0.3/2= 0.15

0.15 = 3/20

3/20 cranberry juice makes 3 servings.

add 3 and 12 to make 15 servings, add 3/5 and 3/20.

3/5= 12/20

12/20 + 3/20 = 15/20 cups of cranberry juice

Answer:

Randall: 44, Amy: 35

Step-by-step explanation:

Four years ago, their age added up to 71. Since four years have passed and they've each grown four years older since then, their ages added up together is 79. Here is the equation for Amy: x + (x + 9) = 79. We can simplify to get 35. Now we add 9 to 35 to get Randall's age. So, Amy's age is 35 and Randall's age is 44, and 35 + 44 = 79.

Answer:

The number is  [tex](S \ u \ C ) = 649[/tex]

Step-by-step explanation:

From the question we are told that  

      The sample size is  n =  800

       The number of seniors is  S  =  519

         The number of  commuters is  C =  430

         The number of of seniors that are commuters is  [tex](S\ n \ C )= 300[/tex]

Generally the number of 800 surveyed students who were seniors or were commuters is  mathematically evaluated as

     [tex](S \ u \ C ) = S + C - ( S \ n \ C )[/tex]

=>   [tex](S \ u \ C ) = 519 + 430 - 300[/tex]

=>   [tex](S \ u \ C ) = 649[/tex]
