Answer:
There is statistical evidence at 1% significance level to support that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
Step-by-step explanation:
Given that among 2180 passenger cars in a particular region, 246 had only rear license plates. Among 302 commercial trucks, 44 had only rear license plates.
Cars Trucks Total
Total 2180 302 2482
X 246 44 290
p 0.1128 0.1457 0.1168
(left tailed test at 1% significance level)
Std error of p =
Test statistic Z = p differnce/std error =
p value <0.0001
Since p is less than 1% we reject null hypothesis
There is statistical evidence at 1% significance level to support that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
Answer:
8
Step-by-step explanation:
2 (2)(2)
2 times itself 3 times.
Answer:
s = 2/3t
Step-by-step explanation:
For some time (t) in minutes, Sarah can iron "s" shirts:
s = (12/18)t
s = 2/3t
_____
If you need to, you can start with a proportion:
shirts/minutes = s/t = 12/18
Then multiply by t to get the above equation.
Answer: a) reflected over x-axis and reflected over y-axis
<u>Step-by-step explanation:</u>
Reflection over the x-axis changes the sign of the y-coordinate
Z = (x, y) → Z'(x, -y)
Reflection over the y-axis changes the sign of the x-coordinate
Z' = (x, -y) → Z''(-x, -y)
A = (-4, 1) → A'' = (4, -1)
B = (-3, 2) → A'' = (3, -2)
C = (-1, 2) → A'' = (1, -2)
D = (-2, 1) → A'' = (2, -1)
