) After the first exam in a large course, the professor surveyed 14 randomly selected students to determine the relation between

the amount of time they spent studying for the exam and exam score.  She found that a linear relation exists between the two variables.  The least-squares regression line that describes this relation is .
          (a) Predict the exam score of a student who studied 2 hours.

          (b) Write an interpretation for the slope. (Refer to Lesson 12.2 for this.)

          (c) Write an interpretation for the y-intercept, if appropriate. If not appropriate, explain why not. (Again, refer to Lesson 12.2 for this.)

20% of the seventh-grade students have math class in the morning. 16 2/3 % of those students also have science class in the morn
Lena [83]
Let x be the number of seventh grade students.

The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.

The 16 2/23% of those students also have science class in the morning means:

16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning

30 students have math in the morning but not science in the morning

83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180

There are 180 seventh graders.

Ana knows the perimeter of her backyard is 6x+14x. if the length of her yard is 2x+3x-7,what is the width of her backyard? answe
vlada-n [284]
Using the simple Perimeter formula we can set up our equation.
p = 2l + 2w
6x + 14x = 2(2x + 3x - 7) + 2w
20x = 4x + 6x - 14 + 2w
10x =  - 14 + 2w
10x + 14 = 2w
5x + 7 = w
Therefore the width is 5x + 7.
