Collinear points are points that lie on the same straight line.
In the figure, we can see that points E, B, and F are all on the same straight line, meaning that they are three collinear points.
Hope this helps.
頑張って!
Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05
Liters can probably be the unit to measure the capacity of a hand sanitizer bottle
If f(-2)=1 and f(1) = 7, then 2 pts on the str. line are (-2,1) and (1,7).
7 - 1
The slope of the line connecting these 2 pts is m = ---------- = 6/3 = 2
1-(-2)
Use the slope-intercept formula. Let the point be (1,7) and the slope be 2:
7 = 2(1) + b; find the y-intercept, b:
7 = 2 + b, so b = 5, and the equation of this line through the 2 given points is then
y = 2x + 5 (answer)
