The correct answer is:
D) Jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.
Answer:
Step-by-step explanation:
4 goes into 64 sixteen times. 64/4 = 16 16 x 4 = 64
The Answer fam is (1/4,7/8)
A^2+b^2=c^2
24^2=12^2+x^2
sqrt(576-144)=x
sqrt(432)=x
12sqrt(3)=x
the answer is c
To complete the square, the second degree term must have a coefficient of 1.
Since the second degree term here has a coefficient of 4, we start by dividing each term on both sides by 4.



Now we can complete the square.
First, we need to find what number completes the square.
We take the coefficient of the first degree term, -7 in this case.
Divide it by 2 and square it. -7 divided by 2 is the fraction -7/2.
Now we square -7/2 to get 49/4.
We add 49/4 to both sides.
