450 miles
1 in. Per 60 miles
460/60 = 7.5 inches
1/2 as a decimal is 0.50
5/6 as a decimal is 0.83 continued so we know 5/6 will come after 1/2
0.83 is closer to 1 so it would be D.
Answer:
-5
Step-by-step explanation:
From your knowledge of multiplication tables, you know that ...
-35 = -(7×5) = 7×(-5)
Then comparing to the given equation, you realize ...
t = -5
_____
Or, you can recognize 7 as the coefficient of t and divide both sides of the equation by that:
-35/7 = (7t)/7
-5 = t

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.
