Answer:
4
Step-by-step explanation:
10. x = 4,-4
11. x = 2,-2
12. Length = 12 yards, Weight = 6 yards
13. x = -5,2
The equation of a straight line in "standard form" resembles Ax + By + C = 0.
Starting with y − 3 = 1/3(x − 6) (which is the equation of a line in point-slope form), remove the fractional coefficient 1/3 by multiplying both sides of this equation by 3:
3y - 9 = x - 6.
We want all terms except for 0 to appear on one side of this equation. Subtract 3y from both sides, obtaining:
-9 = 1x - 3y - 6
Finally, add 9 to both sides, obtaining:
0 = 1x - 3y + 3
This result has the form Ax + By + C = 0, and is thus in standard form.
Alcohol, marijuana is the drug most often found in the blood of drivers involved in crashes.
Answer:
The hypothesis should be retained
Step-by-step explanation:
We are given:
N= 16
n = 4
Level of significance, a = 0.05
From the given data, our ANOVA table will be:
Note: proper ANOVA table is attached
The statistic will be written as:
T = 8/4 = 2
Therefore
The hypothesis should be retained, because we no know that the statistic is in the acceptance area.
