Answer:
The required equation is 
Step-by-step explanation:
Consider the provided information.
Student on the cross-country team runs 30 minutes a day as a part of her training,
30 minutes = 0.5 hours
As we know 
Let the distance she runs in miles, is represented by D, and her running speed, in miles per hour is represented by S.
Therefore, the required equation is: 
Part (A) At a constant speed of 4 miles per hour for the entire 30 minutes.
Substitute S=4 in above equation.



Hence, the required equation is 
Number of Newspaper Published in a day = 300,000
Each news paper must include a Comic section. To check whether each newspaper has comic section or not, the publisher must make a sample Size of 500 or 1,000 will be good . That is , the publisher has to check between Sample size of either 600 or 300 newspapers ,whether it contain a comic section or not.
So, Just Taking a newspaper from a sample size of 600 or 1500 newspapers or 500 or 1000 newspaper and then checking whether it contains Comic section or not will be best way that publisher can adopt.
Time must be kept in mind by the publisher while choosing the sample size.
Answer:
i'm 100% sure its A
Step-by-step explanation:
you didn't tell wich program to use and did not include any pictures.
anyways, I graphed the function with desmos (free to use as app and on website)
so that u can see what the graph should look like.
variance based on the zoom is okay of course.
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.
