Answer:
Step-by-step explanation:
Given
17 % of the drivers stopped have invalid licenses
n=24 drivers are stopped
using Binomial distribution

here p=0.17
q=1-0.17=0.83
(a)none will have valid license i.e. r=0

(b)Exactly one have invalid license i.e. r=1


(c)At least 2 will have invalid license i.e. 



Answer:
Brand 1 Brand 2 Difference
37734 35202 2532

48360 47800 560
38200 37810 390
33500 33215 285
Sum of difference = 2532+ 3664+740+150 −805+ 560 +390 +285 = 7516
Mean = 
Mean = 
a) d= 939.5


=1441.21
b)SD= 1441.21
c)Calculate a 99% two-sided confidence interval on the difference in mean life.
confidence level =99%
significance level =α= 0.01
Degree of freedom = n-1 = 8-1 =7
So, 
Formula for confidence interval 
Substitute the values

Answer:
F&H are vertical angles, D&H are corresponding angles, E&H are adjacent angles, and B&H are alternate interior angles.
Step-by-step explanation:
Hope this helps. Tell me if you need and explanation.
So 9 more than 3 times a number, would be:
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5
