An explanatory variable is a type of independent variable. A response variable is a type of dependent variable. An explanatory variable is used to predict or explain differences in the response variable.
The first coordinate corresponds to independent variable and the second coordinate corresponds to dependent variable.
Since independent variable takes value 5 and dependent variable takes value 15, then the point (5,15) would be the point when plotted on a scatterplot.
Answer: correct choice D
Answer:
Step-by-step explanation:
The research question is given as "Does chewing your food for a longer period of time reduce one's caloric intake of food atdinner?"
Here interest of study variable is "reduction of caloric intake of food at dinner".
For construction of confidence interval, the researcher records the calorie consumption at dinner.
Since calorie consumption is a variable, we need to construct confidence interval for mean.
So correct choice of sentences as "The confidence interval for a mean should be constructed because the variable of interest is an individual's reduction in caloric intake, which is a quantitative variable."
Answer:
Step-by-step explanation:
The distance formula tells you the distance d between the points (0, 0, 0) and (-3, -b, c) is ...
d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²) = √((-3-0)² +(-b-0)² +(c-0)²)
= √(9 +b² +c²)
To get to 20 minutes from 2 minutes you multiply by 10, do the same to the 30 problems to get 300. The answer is 300 problems in 20 minutes.
