<span>Last
year, the average math SAT score for students at one school was 475. The
headmaster then introduced a new teaching method hoping to improve scores. This
year, the mean math SAT score for a sample of students was 491. The headmaster
concluded that the new teaching method produces higher SAT scores. The problem
with reporting results this way is voluntary response. The information of how
the teaching method isnot mentioned.</span>

Even more simplified dividing them would equal 8
Answer:
B) The data represent a linear function because there is a common difference of -9.
Step-by-step explanation:
A linear function is one in which the difference between consecutive y-values is constant. In this table, to get from one y-value to the next we subtract; this means it is a linear function.
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
Answer:
78 miles per hour
Step-by-step explanation:
Formula for speed is Distance divided by Time. (D/T)
The distance between Station A and Station C can be found be adding the distance from A to B and B to C. (20.8 Miles)
Same concept would go for the time.
Time to get from A to B added with B to C. (16 Minutes)
However, the time is in minutes and the question calls for hours. Divide 16 by 60, you get around 0.27.
20.8 divided by 0.27 would be around 77.9, or 78 miles per hour.
Hope this helps :)
