Answer:
could not be the same
Step-by-step explanation:
Given that approximately US drivers are agewise as follows:
<25 13.2
25-45 37.7%
>45 49.1%
Observations are made for a sample of 200 fatal accidents.
Let us create hypotheses as
(Two tailed chi square test at 5% significance level)
Age <25 25-45 >45
Expected 13.2 37.7 49.1 100
Observed 42 80 78 200
Expected no 26.4 75.4 98.2 200
Chi square 9.218181818 0.280636605 4.155193483 13.65401191
df = 2
p value = 0.001084
Since p <0.05 we reject null hypothesis
At the 0.05 level, the age distribution of drivers involved in fatal accidents within the state could not be the same as the age distribution of all US drivers as there seems to be significant difference.
Answer:
This is simple. And, you best not be cheating either.
15 - 1 x 18 / 6
1x18 = 18
18/6 is 3.
15 - 3 = 12
12 is the answer.
Step-by-step explanation:
Answer: <em>3 13/24</em>
Step-by-step explanation:
<em>First off we have an issue with the problem due to denominators not being the same</em>
<em>So we need to find a common denominator</em>
<em>The common denominator would be 24 for 6 and 8</em>
<em>Then we must multiply the numerator 1 by 4 and the numerator 3 by 3</em>
<em>Our new problem would look like</em>
<em>1 4/24 + 2 9/24</em>
<em>Now we add it all up</em>
<em>3 13/24</em>
It’s 130°, because 50+50=100 and 2x is equal to the same angel on the direct opposite side so work where you have 50. then the 4 angles should add to 360° and 360-100= 260, then you have to divide 260 by 2 because it has to be equal to both side so then 260/2=130° and to know that it’s correct add 130+130+50+50 and you get 360°!
Answer:
Try B) 2x - 3y = -9
Step-by-step explanation:
I plotted the points and started to make each answer into the "y = " formula. The only one that passed through all the points was B) 2x - 3y = -9 which I changed into y = 2x/3 + 3
