Hello there.
Question: <span>A school principal wants to find out if his school needs more bike racks. a survey is taken of 30 students who ride their bikes to school. why might the sample be biased?
Answer: It might be biased as the survey was only taken of students who ride their bikes to school. It is most likely that they would agree to it. To make it fair they survey should have been taken of a variety of different students.
Hope This Helps You!
Good Luck Studying ^-^</span>
Answer:
8y°±94°⊂⊂100°
Step-by-step explanation:
The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc
The rule will say x + y = 23
He will pay $1,400 for the computer because 24 x 50= 1,200 plus the $200 down payment equal $1,400
Y=Mx+b is slop intercept form the slope of the line is 1/4 and b is the y intercept which the line crosses over at -3 so it would be Y=1/4x-3
