When multiplying binomials, one takes the first binomial and multiply each term by the first term of the second binomial, and then you do the same with the second term of the second binomial, to obtain:
4a^2+14a-2a-14
4a^2+12a-14

Answer:
The regression equation for the sample is
Y= 0.430x +0.214
Step-by-step explanation:
Using the regression formula;
a= (nSSXY - MX MY)/(nSSX -MX^2)
a= (20×43- 4×6)/(20×98 - (4^2))
a= 836/(1960-16)
a= 836/1944
a= 0.430
X bar= summation x / n =4/20= 0.2
Y bar= summation y / n =6/20 = 0.3
b= y bar - a xbar
b= 0.3 - 0.430(0.2)
b= 0.3- 0.086
b= 0.214
The regression equation
Y= ax + b
Y= 0.430x +0.214
Answer:
450
Step-by-step explanation:
Formula = Number x 100
Percent = 81 x 100
18 = 450
Following shows the steps on how to derive this formula
Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.
81
18% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
18Y = 81 x 100
18Y = 8100
Y = 8100
100 = 450
