Answer:
16 hours
Step-by-step explanation:
velocity = distance / time => distance = velocity * time;
distance = 80 m/s * 12 hours
newVelocity = 60 m/s;
newVelocity = distance / newTime => newTime = distance / newVelocity = 80 m/s * 12 hours / (60 m/s) = (8/6) * 12 hours = 16 hours
Answer:
99% CI for the intercept (b₀) [173.29; 1172.01]dollars
Step-by-step explanation:
Hello!
You have the information of two variables
Y: price of a bycicle (dollars)
X: Weight of a bycicle (kilograms)
The estimated regression equation is
^Y= 672.65 - 1.56X
(191.4) (0.28)
Assuming that 191.4 is the estimated standard deviation of the intercept and 0.28 corresponds to the estimated standard deviation of the slope. The statistic you can use to estimate the intercept is a student's t.
99% CI for the intercept (b₀):
b₀ ± tₙ₋₂;1-α * Sb₀
tₙ₋₂;1-α= t₁₄₈;₀.₉₉₅= 2.609
672.65 ± (2.609*191.4)
[173.2874; 1172.0126]dollars
I hope it helps!

Answer:
144
Step-by-step explanation:
Using the formula they gave of V= l*w*h
w=4, l=3, and h=12
3*4*12=12*12=144in^3
