Answer:
r = 0.9
Step-by-step explanation:
Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.
We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;
r² = 81%
Or r² = 0.81
Thus, the numerical value of the correlation r would be;
r = √0.81
r = 0.9
Answer:
17.8km = 11.125 miles
Step-by-step explanation:
From 5 miles = 8km, we can form the ratio km:miles as 8 : 5.
We want to put the ratio in the form 1 : n, which gives us 1 : 0.625 (we divide both 8 and 5 by 8 to get this form).
Now, using the ratio km:miles as 1:0.625, we have to multiply both 1 and 0.625 by 17.8 to gain the ratio 17.8 : n, therefore giving us the ratio 17.8 : 11.125.
Hence, 17.8km = 11.125 miles
Answer:
2/3 or in decimal form which is 0.6
Step-by-step explanation:
Answer:
the mean
Step-by-step explanation:
A right skewed histogram is a positive skewed histogram (which means the tail is longer the positive direction) that have its tail to the right.
For a right skewed histogram the mean has a larger value that the median because the peak of the skewness is fall in the median range then the mean follow to the right. and the data drive the mean value to the right which increase in value.
Domain is the x and range is y so your domain is 2,3,4,5 and your range is 0 and 4
