degree of freedom = -62.90 ( e )

Step-by-step explanation:

The formula for calculating the F-statistic/test statistic is

test - statistic = Coef ( LBW) / SE Coef ( LBW )

= -0.72399 / 0.01151

= - 62.90

the degree of freedom the F-statistic has = -62.90

F-statistic test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. the value of the test can be gotten from running an ANOVA test or regression analysis on the statistical models

What is the slope of the line with an equation of 5x - 3y = -12

Hoochie [10]

Answer: $m=\frac{5}{3} =1.67$

Step-by-step explanation:

Original equation: $5x-3y=-12$
Subtract 5x from both sides of the equation: $-3y=-5x-12$
Divide both sides of the equation by -1: $3y=5x+12$
Divide both sides of the equation by 3 to get y on the left, leaving the equation in $y=mx+b$ form: $y=\frac{5}{3}x+4$
Evaluate. Slope is equal to m in this form, so the slope is $m=\frac{5}{3}$ .
