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: $56.80
Step-by-step explanation:
71 x .20 = 14.20

Hello :
<span> x4 − 9x2 − 4x + 12 = x²(x²-9)-4(x-3)
=x²(x-3)(x+3)-4(x-3)
= (x-3)(x²(x+3)-4)
= (x-3)(x3+3x²-4)
= (x-3)(x-1)(x²+4x+4)
</span>x4 − 9x2 − 4x + 12 = (x-3)(x-1) (x+2)²

<u>Answer:</u>
Glen uses 15.65 inches fabrics for headbands and 9.68 inches for each player
<u>Explanation:</u>
Given the fabric used are:
For headbands, 641.65 inches for 41 people (39 players and 2 coach)
Therefore, applying the concept of unitary method
41 people = 641.65 inches
1 person = 
= 15.65 inches
For wristbands, 377.52 inches for 39 players
39 players = 377.52 inches
1 player = 
= 9.68 inches
Therefore, Glen uses 15.65 inches fabrics for headbands and 9.68 inches for each player
