Sry i suck in math brother
Answer:
hey! been a while since I've answered questions haha
typically I would put an explanation for my answers but this one's pretty straightforward so ¯\_(ツ)_/¯
a) mode is the number that occurs most often in a data set.
b) mean is the average or expected value in the data set
c) median is the value that lies in the midpoint in the data set.
16, with the factors– 1, 2, 4, 8, and 16 itself
Answer:
D
Step-by-step explanation:
Have a nice day
Answer:
Options (3), (4) and (5)
Step-by-step explanation:
1). a² - 9a + 7ab + 63b
= a(a - 9) + 7b(a + 9)
Now we can not solve this problem further.
Therefore, can't be factored by grouping.
2). 3a + 4ab - b - 12
= a(3 + 4b) - 1(b - 12)
We can't solve it further.
Therefore, can't be factored by grouping.
3). ab + 6b - 2a - 12
= b(a + 6) - 2(a + 6)
= (b - 2)(a + 6)
We can be factored this expression by grouping.
4). x³ + 9x²+ 7x + 63
= x²(x + 9) + 7(x + 9)
= (x² + 7)(x + 9)
Therefore, the given expression can be factored by grouping.
5). ay² + a - y² - 1
= a(y² + 1) - 1(y² + 1)
= (a - 1)(y² + 1)
This expression can be factored by the grouping method.
Options (3), (4) and (5) are the correct answers.
