x=1 or x= 12
Step-by-step explanation:
x²-13x+12=0
x²-12x-x+12=0
x(x-12)-1(x-12)=0
(x-1)(x-12)=0
x-1=0 or x-12=0
x=1 or x=12
Answer:
164.5, if thats wrong then 258.5
Step-by-step explanation:
Divide 94/4 and then you get 23.5 so you multiply 23.5 x 7=164.5 but I wasn't sure if it was either 4 years and then add another 7 or if it was just 7 years so I also did 23.5 x (7+4)= 23.5x11=258.5
100 because they form a supplementary angle which means they add to 180
Answer:
See explanation below
Step-by-step explanation:
It depends on what null hypothesis is under consideration.
One of the most common null hypothesis that are subject of study in a given statistical model is <em>the mean</em> predicted by the model.
In this case, the scientist probably observed that the mean of tusk lengths she obtained in a sample did not match the one predicted with the H-W equation.
So, she decided to perform a statistical study by collecting random samples and measuring the tusk lengths to determine a new possible mean and contrast it against the one predicted by the H-W equation.
<em>Let's call M the mean predicted by the H-W equation, and S the mean obtained by the scientist.
</em>
If M different of S and the p-value is 0.021, that means that <em>there is at most 2.1% of probability that the difference between M and S could be due to a random sampling error.
</em>
It should be kept in mind that the p-value does not represent the probability that the scientist is wrong.
