Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Answer:
Aging schedule
Step-by-step explanation:
An aging schedule can be defined as a schedule that help to shows a company's or an organisation accounts receivables, ordered by their due dates in order for the company or organisation to see if their customers are paying on time reason been that AGING SCHEDULE enables account receivable to be summarized into separate or different time brackets which in turn rank the receivables based upon the days until due or the days past due.
In other word Aging schedule is a table that help to shows a summarized break down of accounts receivable into different time brackets in order for a company or an organisation to easily identify the customers that are extending the time it takes to collect your accounts receivable.
Step-by-step explanation:
Represent Diego's age by d. Then 9d=144.
Answer:
we can say that You drive 43.79 km
Step-by-step explanation:
Distance covered for drive to school = 24.84 km
Distance covered for drive to friends = 18.95 km
We need to find how far do you drive.
It means we need to find the total distance covered
<em>Total Distance Covered = Distance covered for drive to school + Distance covered for drive to friends</em>
Putting values and finding total distance
<em>Total Distance Covered = Distance covered for drive to school + Distance covered for drive to friends</em>
<em>Total Distance Covered = 24.84 + 18.95</em>
<em>Total Distance Covered = 43.79</em>
So, the total distance covered by you during driving is: 43.79 km
Therefore we can say that You drive 43.79 km
Answer:
15 inches
Step-by-step explanation:
1. Use the Pythagorean Theorem: a^2+b^2=c^2
You are already given c (the longest side) and one of the legs which could be a or b.
2. Plug the numbers into the formula and square them.
a^2 + 36^2 = 39^2
Squaring the numbers gives you: a^2 + 1,296 = 1,521
3. Subtract 1,296 from both sides and take the square root of the result.
a^2 = 225
= 15
