An economist calculates that the correlation between walnut prices and peanut prices is r=
q2. you can most likely conclude:
a. there is almost no relation between walnut prices and peanut prices.
b. when walnut prices are above average peanut prices are almost certainly above
average.
c 20% of the variation in walnut prices is explained by a linear relationship with
peanut price.
d. when walnut prices are above average peanut prices tend to be below average.
b. when peanut prices change by $1, walnut prices change by $20.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm
