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.
16x^2-vox=0 when x=2 so
16x^2-vox=0
64-2vo
64=2vo
vo=32 ft/s
Answer:
option B. 
Step-by-step explanation:
we know that
1) The two diagonals of a rhombus are perpendicular
2) The sum of the interior angles in any triangle must be equal to 180 degrees
Let
O ----> the intersection point of the diagonals of the rhombus
In the right triangle OAD
solve for x
Answer:
Step-by-step explanation:
1. There is a total of 16 outcomes
2. To get outcomes with a sum GREATER than 5, we have
2+4, 3+3, 3+4, 4+2, 4+3, 4+4 for a total of 6 outcomes.
3. To spin the same number twice, the possible outcomes are
1-1, 2-2, 3-3, 4-4 for a total of 4 outcomes.
