Curtis and Kim have been given the same two-variable data about the weights of 250 dolphins in captivity and the amount of fish each one eats daily (in pounds). Kim uses a quadratic model in projecting how much captive dolphins eat daily. This model has a coefficient of determination of 0.8766. Curtis uses a linear model in projecting how much the dolphins eat. This model has a coefficient of determination of 0.84775. Whose model fits the dolphin data best? Explain why.

the answer to this question is yes

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

for future students the answer is b

hope i
