The number of students allowed to sit, N=4.
The total number of minutes, T=38 minutes.
Let x be the number of minutes for a student
Answer:
x=3
Step-by-step explanation:
25x+57+x=45x
26x+57=45x
57=19x
x=57/19
x=3
The answer for the blank is 0.003
This is the slope value, which is the number in front of the x in the least squares regression line. Each time x increases by 1, y increases by 0.003
This is the predicted y value of course.
Answer:
a x (b + c) or a x (b - c)
4 × (11 + 10)
or
4 × (22 - 1)
Step-by-step explanation:
20 + 64 = 84
84 ÷ 4 = 21
21 - 10 = 11
22 - 1 = 21
