Hank has read 25 percent of his book. If Hank has read 150 pages, which equation can be used to find the total number of pages i
oee [108]

Answer:

150=\frac{1}{4} x, or 4(150)=x

Step-by-step explanation:

Let's use x to represent the total number of pages in the book.

If 150 is a quarter of the whole book, then 150 is equal to a quarter of x

150= .25(x)

We an go further and multiply both sides by 4 to cancel the .25

4(150)=x

We can finish solving and x=600 pages

 y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

  • Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
  • Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

                               y = mx + c

( -1 , -4 ) is point shown in graph

            slope = -y/x

                     = - ( -4)/-1  = 4/-1 = -4

             - 4 = -4 * - 1 + c

            - 4 = 4 + c

            c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

             y = - 4x + - 8

State the null and alternative hypotheses to test if the population represented by Sample 1 has a mean that is 2.0 units higher
avanturin [10]

Answer:

Null Hypothesis, H_0 : \mu_A-\mu_B = 2.0 units  or  \mu_D = 2.0 units

Alternate Hypothesis, H_A : \mu_A-\mu_B\neq 2.0 units  or  \mu_D\neq 2.0 units

Step-by-step explanation:

We are given the following data below and we have test if the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2;

Pair : 1 2 3 4 5 6 7

Sample1 : 5 6 10 3 6 7 8

Sample2 : 4 4 3 5 5 5 3

Let \mu_A = population mean represented by Sample 1

\mu_B = population mean represented by Sample 2

\mu_D = population mean matched-pair differences for Sample 1 - Sample 2

So, Null Hypothesis, H_0 : \mu_A-\mu_B = 2.0 units  or  \mu_D = 2.0 units

Alternate Hypothesis, H_A : \mu_A-\mu_B\neq 2.0 units  or  \mu_D\neq 2.0 units

Here null hypothesis states that the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2.

On the other hand, alternate hypothesis states that the population represented by Sample 1 has a mean that is not 2.0 units higher than the population represented by Sample 2.
