Speed = 10.5miles/ h
time= 6776miles / 10.5miles/h
= 645 hours
to find time from speed and distance,
use distance/speed
Answer:
X = -2
Step-by-step explanation:
-x - 8 + 14x = -34
-x + 14x = -34 + 8
-x + 14x = -26
13x = -26
x = -26/13
x = -2
-(-2) - 8 + 14(-2) = -34
2 - 8 - 28 = -34
-34 = -34
Step-by-step explanation:
y=3*-2
y=-6
y=3*-1
y=-3
y=3*0
y=0
y=3*1
y=3
y=3*2
y=6
Hope this makes sense
Answer:
a) critical values ≈ -3.182 and 3.182 shows that there is difference in average prices
b) H0 : μd = 0
Ha : μd ≠ 0
Step-by-step explanation:
<u>a) Determine if there is any significant difference in the average prices </u>
using ∝ = 0.05
and μ( advertiser ) - μ ( competitor ) = μd
test statistic ( t ) = -3.011
df = 3
hence the critical values ( two tailed test ) = -3.182 and 3.182. this shows that there is sufficient evidence to show that there is difference in the average prices
<u>b) state the hypothesis</u>
H0 : μd = 0 ( null )
Alternate hypothesis : Ha : μd ≠ 0
