Answer:
The estimated impact of the experiment of offering test preparation classes is:
= 8 scores (in performance improvement).
Step-by-step explanation:
Average standardized-test score for the first 10 high schools = 69
Average standardized-test score for the second 10 high schools = 70
After 6 months:
Average standardized-test score for the first 10 high schools offered test preparation classes = 78
The change in the average standardized-test score for the first 10 high schools = 9 (78 - 69)
Average standardized-test score for the second 10 high schools not offered test preparation classes = 71
The change in the average standardized-test score for the second 10 high schools not offered the prep = 1 (71 - 70)
The estimated impact of the experiment of offering test preparation classes is:
= 9 - 1
= 8.
The volume in the same in both cynclinders would be my guess
8x-6(-6x+4) = 8x+36x-24= 44x-24
Step-by-step explanation:
15.4% of the nuts are pecans.
0.154x = 77
x = 500
There are 500 pounds of mixed nuts in the batch.
39,000; it makes 39,000 cause if its 5 or less then the number stays the same.
