Answer:
What's the intervals for this question
Step-by-step explanation:
Andrew is wrong The mat is only 100 times bigger than the unit, hope this helps :D
Because surface area is a two-dimensional measurement, Benjamin should use m².
(-3/8)x+y=(-4), standard form formula is ax +by = c. So you just move them to the correct sides by adding or subtracting.
Answer:
d. 0.80
Step-by-step explanation:
The given regression equation is
y=0.6x+188
Here, slope=b=0.6
xbar=420, sx=80, ybar=440 and sy=60.
As we know that when y=a+bx, the slope is
b=r(sy/sx)
From this equation we can find correlation coefficient r
b*sx=r*sy
bsx/sy=r
r=0.6*80/60=48/60=0.80.
Hence the correlation coefficient r=0.8.
