Answer:
B. the variability around the regression line.
Step-by-step explanation:
The standard errors represents the distance (how sparse) the observed values fall from the regression line.
Standard errors for regression are measures of the spread of variables around the average (regression line)
The standard error is dependent on the standard deviation of the observations and the reliability of the test.
When the test is perfectly reliable, the standard error is zero and when unreliable, it is equal to the standard deviation of the observations.
Answer:
50 degrees
Step-by-step explanation:
50 degrees because angle 2 is its vertical angle
Answer:
Find the reciprocal of the divisor
Reciprocal of
15/7 : 7/15
Now, multiply it with the dividend
So, 10/ 21 ÷ 15/7 = 10/21 × 7/15
= 10 × 7/ 21 × 15 = 70/ 315
After reducing the fraction, the answer is
2/9
It simplifies to the proper fraction 14/15 so it cannot be a mix number
