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.
Answer:
14
Step-by-step explanation:
1/2x = 1/7x + 5
1/2x - 1/7x = 5
7/14x - 2/14x = 5
5/14x = 5
x = 5 * 14/5
x = 14
Y = 15
Because it’s going to every time by 15
