Solution: The test score that the teacher should expect from a student who did not attend her course is 37.
<u>Explanation:</u>
The teacher's equation for the line of best fit is 
We know the equation for the line of the best fit is:
Where:
is slope of the equation. It represents the rate of change in y as one unit change in x.
is the intercept. It represents the expected mean value of y when all x=0.
Therefore, in the given teacher's equation, the slope is 0.7 and intercept is 37.
Here the intercept means the average score of student who who did not attend her course.
Therefore, the test score that the teacher should expect from a student who did not attend her course is 37.
Answer:
26
Step-by-step explanation:
isosceles traingle:
AB=BC

AC= 3x+5
AC= 3(7)+5
AC= 26
Answer:
There are at least 2 people who have the same pair of (F,L)
Step-by-step explanation:
There are 26 possibilites for F and 26 for L. So there are 676 different possibilities for unique (F,L) pairs. So atleast 24 of the pairs should match with some pair from the other 676. If all the 24 pairs are different, then we have 24 sets of people who have same pair of (F,L). So there are at least 2 people who have the same pair of (F,L). This will be the minimum assuming 676 people span all the possibilities and other 24 people have unique pairs of (F,L).
