Answer: 79 degrees
Step-by-step explanation:
4x+1 + 3x+4 = 180
7x + 5 = 180
7x = 175
x = 175:7 = 25
m8 = 3x + 4 = 3*25 + 4 = 79
The null hypothesis to test the significance of the slope on a regression equation is that the slope is equal to zero.
Given that we have to test the significance of slope in a regression equation.
Equation is relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c. It may be a linear equation, quadratic equation, cubic equation or many more depending on the powers of the variable present in that equation.
Slope is basically a number which indicates the direction of the line.
Null hypothesis is a statement which is tested for its validity and it is nothing but opposite of the result we want.
The standard regression equation be y=mx+c and in this m is slope of the equation.
The line depends on the slope because if it is zero then the value of y becomes zero. So, the null hypothesiss is that the slope is equal to zero.
Hence the null hypothesis to test the significance of the slope on a regression equation is that the slope is equal to zero.
