Answer:
Therefore the length of the hypotenuse is 14.14 inches.
Step-by-step explanation:
Given:
The Triangle is of 45 -45 - 90
Length of one leg = 10 inches
To Find:
Length of the hypotenuse = ?
Solution:
The Triangle is of 45 -45 - 90 ..................Given
So For 45 - 45 - 90 Both the Legs of Triangle is SAME
i.e Longer leg = Shorter leg = 10 inches
Now in Right angle Triangle By Pythagoras Theorem we have
On substituting the values we get
Therefore the length of the hypotenuse is 14.14 inches.
Yes it is true that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars because null hypothesis is rejected.
Given among 2049 Connecticut passenger cars, 239 had only rear license plates. Among 334 Connecticut trucks, 45 had only rear license plates.
let be the probability that commercial cars have rear license plates and
be the probability that connected trucks have rear license plates.
Cars Trucks Total
Total 2049 334 2383
x 239 45 284
p 0.1166 0.1347 0.1191
α=0.05
Hypothesis will be :
It is a left tailed test at 0.05 significance.
Standard errors of p=
=
=
=0.0066
Test statistic Z=p difference/standard error
=(0.1166-0.1347)/0.0066
=-0.0181/0.0061
=-2.967
p value=0.001505<5%
Since p is less than 5% we reject null hypothesis.
We cannot calculate standard deviation so we cannot calculate confidence interval.
Hence there is statistical evidence at 5% significance level to support that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
