Answer:
B Survey a random sample of eighth-grade students
Step-by-step explanation:
In order to reach the best conclusion without biased data, the best sampling method would be B because not only does it survey 8th graders, but it also surveys a random group, ensuring that not all of the students are potentially excelling in and/or having trouble with homework.
Answer:
The product of 4 times the quantity x to the fifth power
28/81 is less than 7/9
28/81 is less than 4/9
The common denominator is 81, so you say 9 can go into 81 nine times, so you multiply 9 by the numerator, so 7/9 is now 63/81 an 4/9 is now 36/81
Answer:
75 = GXD
Step-by-step explanation:
We know that CXE is a straight line
A straight line is 180 degrees
CXE = CXG + GXD +DXE
Substituting what we know
180 = 85+ GXD + 20
Combine like terms
180 = 105+GXD
Subtract 105 from each side
180-105 = 105-105 +GXD
75 = GXD
