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.
Subtract 13 from both sides
-5x = -17 - 13
Simplify -17 - 13 to -30
-5x = -30
Divide both sides by -5
x = -30/-5
Two negatives make a positive
x = 30/5
Simplify 30/5 to 6
<u>x = 6</u>
Answer:
You left out a critical piece of information in the question.
"reaches a height of of the maximum height"
Step-by-step explanation:
Answer:
3/4
Step-by-step explanation:
it's for sure 3/4!!!!!
Each sibling got 1 poster, 8 CDS and 72 books.
<h3>How the belongings were divided </h3>
Since the belongings were divided equally, each sibling would get the same amount of belongings. In order to determine the belongings each person got, we would divide each possession by 3.
- Number of poster each person got = 3/3 = 1
- Number of books each person got = 216
- Number of CDs each person got = 24 / 3 = 8
