Answer:
-3 < x ≤ 8
Step-by-step explanation:
First, write this statement with symbols:
2x - 5 > -3, but also:
2x - 5 ≤ 11
Adding 5 to both sides of the first inequality yields 2x > 2. pr x > 1.
Adding 5 to both sides of the second inequality results in 2x ≤ 16, or x ≤ 8.
Thus, -3 < x ≤ 8 is the shortest way in which to write the given information.

Answer:
The slope is 2.
Step-by-step explanation:
Answer:
No, the population of people is poorly represented with this low sample size. 150 would better represent the population as a whole. 42 people would want to play on Rolling Meadows. (according to the previous data)
Step-by-step explanation:
Most likely this small sample size is too small to gain sufficient data from the whole population. If he were to survey a larger sample of people, he would overall better represent the population as a whole. The percentage of people who would prefer Rolling Meadows in the first sample was 28% (7/25). So just multiply 150 times .28 and get 42. 42 people would want to play on Rolling Meadows.
Answer:
12
Step-by-step explanation:
Your ratio is 24:8. This ratio simplified is 3:1. 4x3=12. x=12.
