The measure of the angle between Ship A and Ship B is .
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Yes, it is a valid inference because he asked all 27 students in his art class
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
Question 2 (Multiple Choice Worth 5 points)
(08.01)Carl takes a random sample of 100 students in his school and finds that 72% of the sample prefers pizza over burgers. There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to prefer pizza over burgers?
72
100
1,080
1,500
No, it is not a valid inference because he asked all 27 students in his art class instead of taking a sample from the school.
9 was the square of 3. The square of -3 is 9 as well
(−3)2=(−3)⋅(−3)=9(−3)2=(−3)⋅(−3)=93 and -3 are said to be the square roots of 9.
All positive real numbers has two square roots, one positive square root and one negative square root. The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots
a2=a⋅a=(−a)⋅(−a)a2=a⋅a=(−a)⋅(−a)A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.
a√aTo indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.
±9√=±3±9=±3Zero has one square root which is 0.
0√=0
