Answer:
x=9/y
Step-by-step explanation:
1)divide both sides by (2y)/3
2/3xy/2y/3=6/2y/3
x=9/4

Answer:
The correct statements are A & C.
Step-by-step explanation:
<u>Standard deviation:</u>
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
- A low standard deviation means that most of the numbers are close to the average.
- A high standard deviation means that the numbers are more spread out
Statement A is correct, City A's heights are more spread than City B's, because. City A's standard deviation is greater than City B.
Statement C is correct, because city A's mean is lesser than City B.
Answer:2, 1, (in place of x) and y2
Step-by-step explanation: Divide your base numbers, which are 18 and 9, so you get 2. Then because you're dividing with exponents you are just subtracting them. So x 2-2 (Imagine these as exponents) so you'd get x0. Next you'd do the same with y so you'd end up with y2. Because your exponent is 0 on x it equals one.
