Answer:
c. No, for each height, there are people of different ages.
Step-by-step explanation:
We say that y is a function of x when there is a relationship between x and y. For example, the distance you run on a single day and your average speed.
However
There is no relationship between age and height. For example, we may both be the same age and have very different heights.
So the correct answer is:
c. No, for each height, there are people of different ages.
So what is given is:
length = 1.9 * w, you want to convert this to w = ...
This is done by dividing left and right by 1.9, so you get:
length/1.9 = 1.9*w/1.9, which simplifies to w = length/1.9
Another approach is to replace the multiplication with a simpler one in your head. So in stead of reading "length = 1.9 * width, what is width?", you read "6 = 2*3, what is 3?". You'll immediately realize 3 = 6/2, and that shows you how to change the real equation, ie., width = length/1.9.
Answer:
Step-by-step explanation:
Answer:
Null hypothesis (
): The birth weight of the first born of identical twins is the same as the birth weight of the second born.
Alternative hypothesis (
): The birth weight of the first born of identical twins is higher than the second born.
Step-by-step explanation:
Please note that the null hypothesis is the hypothesis we always want to reject or prove to be false. Hence in this study, the objective of the study is clearly stated that the researcher want to determine whether the twin born first tends to weigh more than the twin born second.
Therefore, the null hypothesis we assume that the weight of the identical twins is the same regardless of who come first or last., while the alternative hypothesis is constructed or stated to answer the research objective.
