$$ r=0.44 $$
Discussion given that the opera empty we equal to the t E to the t then t eat the D on were also given that the r zero equal to the 111 and the person asking to find our empty here energy do that. First of all, we will integrate almost side on this question and we do so on the left hand side. We got the arm t and on the right hand side there until you live there with the ego to the T square. Our two plus, let's see one until you lived under 80 Ego to eat the T plus See you and then you live there. This one you know is a well known We go to the A to the d A, then minus into the day, that's a constant C three. And now we want to block in the value zero for the tea. So are obviously are get equal to the C one on, then one glass CQ and then we have the, um, my nose one plus e three and we want to make a niko tube the 111 So it means that we should have to see one must equal to 11 plus C two must equal to one and minus one plus c dreams equal to one. So from here we get to see one equal to one C two equal to zero and C three equal to two as a result of God. Artie, we go to you that d square with you plus one e to the T and then they eat the three months 80 plus two.
You want a subtract sits one is there he is. Three minutes. 503 minus two is one for minus three is one in one minutes. One is here, so our answers that
Welcome. We're here today to determine the coefficient of determination and the coefficient of non determination and explain what those mean in context before we dive into the calculations, lets loose what we know. We know that our correlation coefficient R is equal to point five one. Using that information, we're going to start out by calculating the coefficient of determination, and we know that our coefficient of determination is our square wish. In this context, that means it is equal to point 51 square, which equals point 2601 otherwise known as 26 0.1%. Explaining what that means in context, we know that 26.1% of the variation in the dependent variable can be attributed to the variation in the independent variable. Now, we don't know exactly what the independent or dependent variables are in this context, but if we did, we could specify our answer a little bit better. Moving on to the coefficient of non determination, we know that our coefficient of non determination is equal to 1.0 minus are square that is equal to in this context 1.0 minus point 2601 which is equal 2.7 three nine. I'm gonna make that a little bit Meter seven three nine nine, which is equal to 73 0.99%. Explaining what that means in context, we know that 73.99% of the variation in the dependent variable is due to chance. I hope this hoax and keep at the great work.
Looking I r spectroscopy. So invert spectroscopy, fastly if we look at our definition. So this is the analysis of infrared light that is interacting with a molecule. So this could be analysed in three ways from measuring the absorption. The commission, Auntie Reflection. So the main use of this technique is then organic and inorganic chemistry specifically on it is used by chemist in order to determine functional groups in molecules. So in this example, were given a structure. And so now we're gonna look at some absorption is that we might expect to see in this molecule. So firstly, we have a C and triple bond, which we would see it absorb about 2 to 50 wave number. So this is slightly stronger than all kinds. However, a little love it when conjugated. Secondly, we've got a weight which is our alcohol functional group, which is observed between 3600 I'm 3500 wave number. Lastly, we've got the CC bond and this is seen between 1616 80 centimeters to the minus one, which is considered our wave number
