Answer: The p-value is 0.154.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis :

Alternate hypothesis :

Population mean = 20 hours
Sample mean = 18.5 hours
Sample standard deviation = 4.3 hours
Sample size n = 35
So, test statistic would be

So, the p value would be 0.154.
Hence, the p-value is 0.154.
Answer:
<u>greater than what it was before</u>
Step-by-step explanation:
<em>Remember</em>, a tornado usually causes significant structural damages to houses within its area of impact., and this requires running expenses to repair the damage.
Hence,<u> since the term </u><u>expenditure, </u><u>also implies expenses; we can expect the total expenditure on housing after the tornado to be </u><u>greater than</u><u> what it was before the tornado since families would be paying for repairs.</u>
Answer:
⟨-5, -1⟩
Step-by-step explanation:
Vector:
A vector is given by its endpoint subtracted by its initial point.
Vector u has initial point at (3, 9) and terminal point at (–7, 5)
Then

Vector v has initial point at (1, –4) and terminal point at (6, –1).
Then

What is u + v in component form?

⟨-5, -1⟩ is the answer.
56 miles : 1 hour
/2. /2
28 miles : 30 minutes
56+28. 1h+30m
84 miles : 1 hour 30 minutes
84 is the answer
