Answer:
a. is not found to be significant.
Step-by-step explanation:
Regression analysis is a statistical technique which is used for forecasting. It determines the relationship between two variables. It determines the relationship of two or more dependent and independent variables. It is widely used in stats to find trend in the data. It helps to predict the values of dependent and independent variables. In the given question, there are 25 observations and the regression equation is given. X and Y are considered as dependent variables.

Let's just do a bunch of math below.
7.8 X 103 ?
-------------- = ------
1.2 X 104 ?
So, first, we're gonna do 7.8 multiplied by 103 to get 803.4.
Thus....
7.8 X 103 803.4
-------------- = -----------
1.2 X 104 ?
Then we would do 1.2 multipied with 104 to get a product of 124.8.
Therefore....
7.8 X 103 803.4
-------------- = -----------
1.2 X 104 124.8
Dividing 803.4 by 124.8 would get you a quotient of 6.4375.
Your answer is 6.3475.~
Have a nice day~
Answer:
Hope this helps
Step-by-step explanation:
1. Make 5 3/4 into an improper fraction. That would be 23/4. 2. Write 4 in a fraction way. That would be 4/1. 3. Now do 23/4 X 4/1. That would be 92/4. 4. Turn it into a mixed number by doing 92 divided by 4. That would be 23. No fraction after 23. Jacob rode his bike 23 miles this week. :)
y-2 = 3(x+7) put it in y=mx+b form (slope intercept)
y-2 = 3(x+7) distribute 3
y-2 = 3x+21 add 2 to both sides
+2 +2
y = 3x + 23
so now the slope of that is 3 so the new equation has a slope of 3 because parallel slopes are equal.
my new line has a slope of 3 and point (4,2)
so we use point slope formula y-y1 = m(x-x1)
y-2 =3(x-4) put it in y=mx+b form (slope intercept)
y-2 = 3(x-4) distribute 3
y-2 = 3x -12 add 2 to both sides
+2 +2
y = 3x + 10 which is you line slope intercept with parallel slope and contains (4,2)
