Note that Cheryl wants to find the number of hours <u>seventh grade boys and girls</u> spend on homework each week.

There are multiple causes of a biased sample.  Two of the most obvious ones I find are:

1.  She's surveying <u>girls</u>, but she is trying to get data on the number of hours <em>all</em> seventh graders (boys <em>and</em> girls) spend.

2. She's surveying 50 girls from the <u>entire school</u>, although she is trying to get data on seventh graders only.

Sergeeva-Olga [200]

Answer:

$31.05

Step-by-step explanation:

8% of 25 is 2

25 + 2 = 27

15% of 27 is 4.05

27 + 4.05 = 31.05

              Solve the Inequality.

\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}

              x<-4

\blue{\textsf{\textbf{\underline{\underline{How\:to\:Solve:-}}}}

                      First, add 6x on both sides:

-2x+3+6x<-13

Add the x's:

4x+3<-13

Now, subtract 3 on both sides:

4x<-13-3

4x<-16

Divide by 4 on both sides:

x<-4

So the values of x that are less than -4 will make the given inequality true.

<h3>Good luck.</h3>
