The statement is true. If x and y are both real numbers, the statement is:
"for every x, there exist y such that "
This is true, because you can pick any real number, square it, and obtain another real number, y. The relation is not surjective, i.e. we will not use all possible values for y, but it doesn't matter. The statement is only asking to find a value for x^2, which we can always do.
The answer is A. Subtract the five on both sides and you end up with A :)
Answer:
1710
Step-by-step explanation:
GPA = 3,1 +- 0,6
0,6 = 2*STDEV
As it is a normal distribution, the interval (Mean +- 2*STDEV) includes 95% of the students.
1800 * 0,95 = 1710
Answer:
Step-by-step explanation:
8y + 11 = 4(y - 2)
8y + 11 = 4y -8
subtract 4y from both sides
4y + 11 = - 8
subtract 11 from both sides
4y = -11
divide by 4 on both sides
y = -2.75 or - y = 2.75
if you need a fraction it would be 2 3/4
