The general form for a linear equation is given as: y = a + bx. In the regression equation, b is called the ______.
Viktor [21]

Answer:

Slope

Step-by-step explanation:

In the regression equation y=a+bx, y is dependent variable and x is independent variable. It means that due to change in x the y changes respectively. The "a" is intercept of the model and it shows the value of y when x is zero. The "b" is the slope of the model and it depicts the change in y due to unit change in x. The positive value of b means that as the x increases y also increases and as the x decreases y also decreases. The negative value of b means that as the x decreases y increases and as the x increases the y decreases.The sign of b shows the type of relationship between independent and dependent variable.

Leto [7]

Answer:

0.3276%

Step-by-step explanation:

-The percentage of error is the the percentage deviation from the real value.

-Given the real value is 427.4 m and the pedometer value is 426m, the % of error is calculated:

e={Actual -Reading}\\\\=427.4-426\\\\=1.4\\\\\therefore\% e=\frac{e}{Actual}\times 100\%\\\\=\frac{1.4}{427.4}\times 100\%\\\\=0.3276\%

Hence, the percentage of error is 0.3276%
