Identify the variation as direct, inverse, joint or combined. a1b1/c1=a2b2/c2 combined inverse joint direct

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

the answer is 5/14.

hope this .
