You can find a common denominator using the two denominators multiples.
The value of a = 2.17 and b = 1.95.
<h3>What is regression line?</h3>
A regression line is a graphic representation of the regression equation expressing the hypothesized relationship between an outcome or dependent variable and one or more predictors or independent variables;
y=
Correlation:
r=0.964
R-squared:
r²=0.9292
Hence, value of a and b is 2.17 and 1.95.

If you want to solve this problem using formulas, there are two important formulas:
t1 = first term = -5
tn = nth term = last term = -5
n = numbr of terms
Sn = sum of the n terms
tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)
65 = -5 + 5n - 5
65 = -10 + 5n
75 = 5n
n = 15
Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2
Sn = 450
So ur answer rounds up to 450

N+(n+2)+(n+4)=51
Which isn't possible because an even plus an even equal even!
If you want to find half of how many of something divide that number by two. For example if Diane has 8 quarters that you would say 8÷2= 4. So half of the number of quarters Diane has would be 4. Here is another way to do it: You could also multiply 8 by 1/2. And 8•1/2 would be 4. I hope this helps!
