Step-by-step explanation:
A sequence is geometric only if has common ratio i.e. whiere a1,a2 and a3 are first,second and third term of the sequence respectively.
1) Common ratio
Explicit formula
Now using the above formula, we can find
2) Here
so this is not geometric sequence so no need to proceed further.
3) Common ratio
Explicit formula
Now using the above formula, we can find
4) Common ratio
Explicit formula
Now using the above formula, we can find
5)Common ratio
Explicit formula
Now using the above formula, we can find
6)Common ratio
Explicit formula
Now using the above formula, we can find
<h2><u>Answer with explanation</u>:</h2>
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.
Let a and c represent, respectively, the price of an adult and a child ticket. We know that
Multiply the first equation by 3 and the second equation by 2 to get
Subtract the two equations to have
Plug this value in the first equation to get
