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>
Hey there!
Palindromes are numbers that can be written the same way backwards, such as 101 and 12321. You're looking for some numbers which are palindromes, and so are their square numbers.
Alright, I'll give you four of those:
- 121 is a palindrome, and its square root is 11, both palindromes. 11 x 11 = 121
- 484 is a palindrome, and its square root is 22, both palindromes. 22 x 22 = 484
- 10201 is a palindrome, and its square root is 101, both palindromes. 101 x 101 = 10201
- 12321 is a palindrome, and its square root is 111, both palinromes. 111 x 111 = 12321
Hope this helps!
4x + 11 = 8x + 1
11 = 4x + 1
10 = 4x
/4 /4
2.5 = x
X = 2.5
