Let 
be the distance traveled by deluxe tire .
As per given , we have
Null hypothesis : 
Alternative hypothesis : 
Since 
is left-tailed and population standard deviation is known, thus we should perform left-tailed z-test.
Test statistic : 
where, n= sample size
= sample mean
= Population mean
=sample standard deviation
For 
, we have
By using z-value table,
P-value for left tailed test : P(z≤-2.23)=1-P(z<2.23) [∵P(Z≤-z)=1-P(Z≤z)]
=1-0.9871=0.0129
Decision : Since p value (0.0129) < significance level (0.05), so we reject the null hypothesis .
[We reject the null hypothesis when p-value is less than the significance level .]
Conclusion : We do not have enough evidence at 0.05 significance level to support the claim that t its deluxe tire averages at least 50,000 miles before it needs to be replaced.
Its is a function. mentally connect the dots. run your pencil across the paper parallel to the y-axis. if none of the points have touch the pencil it is a function. another way to check. look at the X value of all the coordinates. if they are all different its a function.
Time = distance/speed, so
3.54x10^7 / 3x10^8 = 1.18x10^-1
or, 0.118 seconds
Answer:
9/5 = 1.8
All you have to do is divide the numerator by the denominator.
Hope this helps!
