Scientists measured the size of Dungeness crab shells over a 10 year period from 1982 to 1992, both in
nature and in the laboratory
x = premoult (before shedding) shell size (mm)
y = postmoult (after shedding) shell size (mm)
This bivariate data set was modelled using a linear
least
squares regression line 9=0.9056x+26.729
with a correlation coefficient of r = 0.990.
Predict the value of a postmoult shell in mm, given
that premoult shell size was 90 mm.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

i wish i could you, i have no idea how to answer this

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
