Answer:
= 2.87 × 10-2
(scientific notation)
= 2.87e-2
(scientific e notation)
= 28.7 × 10-3
(engineering notation)
(thousandth; prefix milli- (m))
= 0.0287

8y-9-4y+5=12y-4-5y
4y-4= 7y-4
Add 4 to both sides
4y=7y. The only answer is 0
1. 1/5 = x - 9 / x
2. Cross multiply x = 5 (x - 9)
3. Distribute x = 5x - 45
4. Move the variable and change the sign x - 5x = -45
5. Add like terms -4x = -45
6. Divide x = 45 / 4
So the solution is x = 45 / 4 or 11.25
The correct answer is 2– it is NOT a possible value for correlation coefficient (r) because the value of “r” must always be between +1 and –1.
